The Things I've Learned: Restrictions: There were no restrictions on my bike, but I hear about a lot of them being all over the place. First there's something in the carb that restricts fuel deliver, there are restrictions in the airbox that reduce the air you take in reducing speed, then there's a washer in the variator preventing the belt from riding high, then there can be restrictions in the exhaust such as a washer welded on to prevent you from reaching your top speed. Remember to try to stay within the confines of the law when thinking about your speed. Illinois requires a class L license for anything that goes over 30mph. Valves: Valve Adjustment is crucial! When you get your scooter initially the valves are extremely tight more than likely and this causes plenty of problems, making your scooter hard to start and reducing performance while making it unable to maintain idle, and dying, etc.! Adjust your valves to .003 in, .004 out if you have a scooter like mine. Oil: Oil is as important as it is in a car, you can't have too little, and too much is bad too. When you first get your bike you need to use that dinosaur based oil and after 2k miles or so it's allowable to use synthetic oil. Gear Oil: Gear Oil is important too! Without it you risk seizing your engine or something I guess. High quality gear oil will also increase your performance a bit over the stock junk that comes inside your scooter from China. Idle Adjustment: You want to have your idle high enough that your headlights don't dim and low enough that your back tire doesn't spin. It's a difficult balancing act for a newb, and your A/F adjustment will mess with your idle too if it's off by too much. A/F Adjustment: Your air fuel ratio is apparently crucial to the engine. Too much fuel won't do much damage unless you're off by quite a bit, but too much air makes your engine run too hot risking all sorts of damage. If you have a freeflow filter you will not be able to adjust the A/F properly if you have a stock idle jet, you will need to restrict your air intake enough that you're not getting too much air. An idle jet of 38 should fix this. Air Filter: Your air filter is an airbox when your scooter comes stock. This airbox is designed entirely to restrict air in a very specific way so as not to deliver too much air to the scooter. It is there to prevent damage, but it can also reduce performance in some cases, such as after installing a big bore kit. My airbox was damaged which caused me to have to replace it with a freeflow filter which was cheaper than replacing the stock box. The freeflow filter gave me nothing but trouble until my problems were identified at the cycle mechanic. My filter had to be taped in order to resemble the restrictions on the airbox so as not to deliver too much air during idle. Until I got my 38 jet I had to run my scooter with a ghetto-taped filter just in order to run. The Battery: You want a decent sized battery. A flatout replacement for your stock is NOT good enough! You need something with more amperage, learn from my mistake. I can't even have a stereo plugged in without the battery draining on the way to the store. This also has to do with your stator being able to supply enough voltage and your idle being high enough not to discharge the battery. Clutch Springs: Clutch springs come in three non-uniform varieties from each brand. there are 1k, 1.5k, and 2k, plus others. Each number represents the additional RPMs that your clutch should engage at. I installed 2k springs in my clutch so that my takeoff acceleration would be much better, the only thing it restricts is how slow you can go. Too tight of springs may mean you can only go 10mph or higher. If you want to keep your low end speeds and you're satisfied with your takeoff then there isn't really a need to change them. I just really like my better takeoff. Variator Weights: I've learned a lot from messing around with my variator weights, and I would highly reccomend you buy yourself a kit of sorts to test out the different combinations until you find your perfect match. These really depend on your location, the roads you take, your weight, and other variables such as how fast you want your topend to be versus how fast you want your acceleration. There are Rollers and Sliders, stock scooters normally come with rollers, and they come in a variety of weights. Sliders, especially Dr. Pulley sliders, advertise higher topend and faster acceleration in general, however you need to add an additional 1g to equal the same weight of rollers. You will need a gram scale in order to weigh the ones that come with your scoot. The ones that came in mine were 6.5g. I myself found the perfect balance at 6.5g in the form of sliders, which is the equivalent of 5.5g rollers. Your variator weights are crucial in finding your optimal performance. CDI: I don't know much about the CDI, but I do know that stock ones often come with a restriction which causes your scooter to be unable to reach its highest rpms. A high performance cdi removes this restriction and offers a better rpm range for better acceleration and top speed. Re-Jetting: Rejetting is difficult and time consuming and requires you to take apart your carburetor multiple times. First you have to buy a fist full of sparkplugs, a range of sizes of jets, then you have to do what is called a plug chop every time you install a new jet. This indicates whether you go higher or lower in jet number. My main jet was due to the free flow filter, my idle jet is 38, again, due to the free flow filter. My stock should have been somewhere around 78 main and 32-35 idle. Rejetting to the perfect size is very much worth the trouble because you chance getting better performance, gas mileage, and longevity out of your scooter. Having the wrong jet size can severely impact performance and longevity. PAIR system: There's an emissions system on a lot of scooters that brings fresh air into the exhaust to help with emissions. Get rid of it! If you want performance you're going to have to plug the extra nipple going off of your intake manifold and remove the whole thing that attaches to your valve head. Warning: You will need a replacement valve head which does not offer the PAIR system in order for this to work properly. BBK: A Big Bore Kit often comes with an engine Cylinder and Piston (plus piston rings, gaskets, etc.) and the goal of the Big Bore Kit is to up the displacement of your engine. A 44mm BBK is 63cc, a 47mm BBK is 72cc, and a 50mm BBK is 81cc. These take a lot of work to install, and on my scooter I had to completely remove the engine from the frame just to access the parts necessary. With more CCs of fuel and air comes more power and performance. Depending on what you're after I'd say a BBK is totally worth the trouble. Once a BBK is identified (such as with the Secret 60) or installed, upjetting will be absolutely required. All BBKs with a free flow filter will require jets through just to be safe. Gears: Gears effect the rpms in which your tire turns at what speed. In order to up gear you will have to first decide whether you want better acceleration or higher top speed and then you will have a variety of gear sets to choose from. The 16/50 gear set offered by scrappydogscooters offers a 6-10mph increase with only a tiny bit of reduced acceleration. The small shaft which comes in the gear set will have to have your original gear pressed on to it at a Machine Shop, DIY methods seldom work, if at all. P! Sticker: Possibly more crucial than a gremlin bell, this sticker is from the Anime show FLCL and stands for "the pillows" an amazing Japanese rock band.

I'm just posting a copy of this in all forums in case it helps somebody. I'm reposting this because I have updates and have made progress on my scooter since my last update and I hope that this thread will some day help someone else get more performance out of their scooter because it should contain a wealth of information by now. EDIT: Re-titled this post, Blah, blah, blah, scroll down for updates
Hello all.
I'm the one posting about my new Bashan Peace Sports 50 2009 scooter (49.9cc), the first scooter I've ever owned that's street legal.
Currently my top speed is 20mph and there is no full throttle. It takes possibly a solid minute before I can reach 20mph on a flat road too. I'm using a busted up throttle case assembly right now, but I'm positive that's not the issue.
It appears to have a sort of sweet spot at around 75% throttle, but anything higher than that puts it back in idle. What's going on here? As far as I know the carb has never been cleaned and despite having 1.4k miles on it it still had the stock sparkplug and oil (the previous owner must've hated this poor thing). I've since replaced the sparkplug and oil and there's no more dying at stops or bogging during idle, but I still have this issue with the throttle. Is it just normal to not be able to go over a certain throttle percentage? I can't join traffic going 15mph for a minute before I reach the speed of the other cars.
I currently weigh 240lbs, but carrying a 20lbs bag of salt didn't seem to effect performance.
So... I'm sorry for my poor description skills, but what should be done, in your opinion? Is it the carb? The fuel? The idle? The air/fuel ratio? The fuel line? or something I'm unaware of? If at all possible I'm willing to have a go at any possible way to draw more performance out of this thing with some direction. This is my primary and only vehicle, I need it to be able to go just 35mph, not 25 downhill. Is this even possible to achieve? Because right now every car is passing me in the neighborhood on my way to the local grocery store. Main roads are just an impossibility.
Should I sell my precious first scooter and try to get a 150cc or is it possible to draw enough power out of it to go to my optimistic goal of 35mph?
UPDATE 1/19/13 Still working on hitting 35mph, I can go up to 31mph right now, just looking for that last limitation. I got my feeler gauges in the mail today, so I'll be doing a valve adjustment soon.
UPDATE 1/20/13 Finished the valve adjustment, hearing no clicking. Haven't been able to ride for almost a week because of my hurt ankle, but I'm still working on it. Ordered a new battery and now I'm trying to figure out my throttle problem.
UPDATE 1/23/13 Tightened my throttle and it seemed more responsive for the few minutes the scooter would run. Found my old work boots and they have been helping support my ankle, I'm feeling good enough to go for a ride in the chilly weather. I'll be updating again once I get my new battery!
UPDATE 1/24/13 Got the battery yesterday, tried charging it but the light instantly went green so it came fully charged as advertised. Loosened the throttle a bit. Been trying to start the scooter for two days now! Boy, do I regret ever letting it with an empty tank of gas. Heet seems to have made the scooter able to start for a minute at most, but it won't stay running no matter what I do. I'm thinking the cold weather has something to do with it. Or maybe everything to do with it, I'm not sure.
UPDATE 2/3/13 Took off my carb and drilled/chiseled out the plug that was blocking my a/f. Put a # jet in there and my throttle dilemma seems solved. Have yet to ride due to bad weather though. I will continue to update this thread as I was updating through the other forum for a while and now some of my progress is lost in history.
UPDATE 2/15/13 Finally got to riding today! After weeks of bad weather. My throttle is great and responsive, I can go full throttle no problem, and I have finally reached my goal of 35mph (up a small hill no less!), I know I can go faster, but I have yet to find a road I'm willing to try to on, haha.
UPDATE 5/23/13 My original thread got deleted so I'm re-posting it from the old scootdawg forum. I've done a lot since the last update. I've played around with slider weights, restricting my freeflow filter, breaking and then fixing my kickstarter, etc. I've found a polish village in which to test my speeds on. There's an awesome hill that goes on for about an eighth of a mile which allows me to test my speeds uphill and downhill, while my flat terrain speeds have reached 40mph+ allowing me to join traffic and fully test my limits on the main roads. At 267lbs, the following checklist has allowed my top speed to reach 40mph on a mere 63cc scooter. I now go 50mph downhill, 35mph uphill, and 40mph+ on flat terrain.
UPDATE: 6-7-13 So yesterday I installed my 50mm BBK from Techdirect on amazon. The power is incredible. Takeoff is great. Acceleration is crazy awesome. And the sound of my performance exhaust makes it seem like a big motorcycle, haha. I have yet to break in the top end so I have yet to reach WOT yet, but I will be updating with the speeds I can hit.
UPDATE: 6-12-13 My BBK break in has been going great. I performed a compression test and the reading was 155PSI. I've done my 100 mile oil change and found no metal particles, but some crud was in the screen so I blew it off with the air compressor. Since I did my initial 50 miles I'm able to go WOT without too much concern (but only for 10-15 seconds at a time!) so I've updated my speeds below. It was quite a huge leap going from 63cc to 81cc.
UPDATE: 6-18-13 I finally installed my performance gears after a day and a half of struggling with them. Now I've hit speeds of 51mph and my quest for power is nearing completion. I'm already way beyond what my initial goal was. First I wanted 35mph so I could go on route 120, then I wanted 45mph so I could go to my bank. Then I wanted 50mph just so I wouldn't have to go full WOT going to my bank, and now I'm hitting 51mph! If you would've told me I could've achieved this with this little scooter when I first got it I would've thought you were crazy - but here I am, overweight and still hitting high speeds
UPDATE: 6-20-2013 I got my koso variator in the mail yesterday! I swapped my 4g sliders for 9g and I seem to have much smoother acceleration. I'll be updating my speeds later today. It feels like I could go down by a gram or two, but as it is it's tolerably fast acceleration, and hopefully a higher top speed!

An expert harley rider who has been riding for some 25-30 years sat me down once and showed me how to make a rain suit out of a garbage bag. You just cut armholes, a head hole, then put it on! It's that easy

I thought I was getting a steal when I first got one of the rarest scooter ever; the Honda Zook... Now that I have it there's nothing I can do with it because there are no parts available anywhere.
Careful and good luck!

[replyingto=nwhicks21]nwhicks21[/replyingto]That depends on how much power you want versus the longevity of your engine. Supposedly the crankshaft will break sooner the higher in cc you go.
I need my bike to last, but I also need my bike to go 45mph with ease, and as long as I ease off the power and don't push my scoot too far it should last me with a 100cc kit, which is what I'll be getting.
Note that there is no true 100cc kit, that is normally a 50mm bore which is something like 82cc or something. The "80cc" kit is 72cc, unless you already knew that..

You have to match the cdi that you currently have otherwise it will just break.
AC is the most common and it often has a 4pin and 2 pin, with two wires coming from the two pin connector. DC CDIs are supposed to be a lot bigger than the AC ones and they tend to have a 4pin and a 2pin with only one wire sticking out of it.
Be sure to check out what CDI you already have:

Found a Hornet scooter, don't know what year, but the guy only wants $250 amazon credit... It looks exactly like my scooter, except a different brand. Only problem is... He wants gas money to deliver And me without any gas money... I was so dang close... EDIT: It's page two, time for another shot of vodka and another song...

[replyingto=millsc]millsc[/replyingto]Heya, Millsc! Y'know, I've learned a lot about BBKs from your archived posts...
I've got a 2009 Bashan Peace Sports 50, it's a secret 60.

[replyingto=tvnacman]tvnacman[/replyingto]I planned on ordering some time next month, but money is tight so I may have to wait longer than that.
I really appreciate the help, I'll let you know if I end up ordering from your site instead of amazon, the Amazon deal is rather tempting for me because I have an abundance of amazon credit and not so much a lot of cash, haha.
