arbSolved.
5 rollers were on their sides and 1 was in place however all of them were jacked up!
replaced and cleaned everything up with a cloth. btw everyone Harbor Freight has a 12V emergency impact wrench set for 20 bucks... 21.50 or so, it hooks up to our scooter battery or a car cigarette outlet. It got the variator off in 2 tugs.. was a beautiful thing..
running perfectly, thank you all! your help won this one!

So I got into it today and began examining the problem.
When I start the bike in its current state it starts bogs and shuts down, if i start it and give it throttle, the clutch still knocks but it does idle normally, while idling you can hear the knocking of the clutch (after holding my hand on the bell while idling it seems like it is coming from a rotating piece in the clutch bell). Another analysis is that it seems when the bike is on and I rev up the engine on center stand the belt is staying in one spot on the variator and clutch, it seems like neither are opening and closing as it should, also when I turn off the bike the belt sits about halfway into the clutch and the clutch stays open about halfway instead of closing and pushing the belt to the top. What I think may of happened was when my belt broke at high speed so suddenly it must've locked the clutch somehow into a higher gear which may explain why I can't take off for sh... but once I give her a minute at 5-10MPH she takes off and hauls...
I planned on buying a impact wrench today but was unable due something coming up so I tried my own little operation to get the clutch off unsuccessfully, I didn't want to take a chance of stripping the bolt so I gave up and said I'll wait for a impact wrench. Also will I need anything to hold the bell while using the impact wrench on it or can I just use my hand, likewise for the variator?
Again any comments and input helps, I'll continue posting updates just in case someone runs into this in the future!

Honestly I didn't take it off, I watched a video on youtube and simply just followed it and it slipped right on, no damage to the belt. (Man that sounds stupid lol but it's how I've fixed a few problems so far). I am going to harbor store tomorrow to pick up the a wrench just got off the phone with them. I'll take it off tomorrow and take a look at what is going on and update.
Honestly I don't know what rollers are but I'll definitely research it after this post and see if I can do that tomorrow as well.
Thanks guys!

Thanks you guys for the quick responses. What kind of wrench will I need to get that off, I have a 17MM and ratchet but I'm pretty sure it will need like a impact wrench or torque wrench? Anyone know any main stream stores that sell them pretty cheaply? I'm new to scoots but honestly having a blast taking it apart and getting to know it better replacing these worn parts since I plan let make this a family ordeal, packing the streets with 5-6 scoots at once.

It's a 2008 Chaunl Longbo Adventure 150cc LE (LB150T-12) GY6, it has 2400 miles on it, I bought it at 1900 miles about a month ago. When first bought she dripped a couple drops of oil out of the air box, which has since been fixed (overfilled on oil), they removed the air filter as well probably due to it being soaked but I have since bought a new one. I've cleaned the spark plug, adjusted the air/fuel ratio, replaced a couple bulbs and just pretty much cleaned her up. She has been riding great for the past 2 weeks, roughly 45-48 on the odometer with me and my wife on it and honestly the same with just me but that's really all I need for the city. I took her out to lunch on Sunday and when riding home we felt a nice jerk and everything completely died, I pulled over and tried to start it up and it was a no go, we waited about 5 minutes and started it up and it sounded fine so we jumped on it and went absolutely no where ha. Everything sounded normal she revved up great but the wheel didn't budge even on center stand. I figured hey it's an older scoot probably just the belt. I left her in the autozone parking lot (my scooter) and came back today with a brand new gates kevlar belt, I opened it up and sure enough the belt was beat to... however I was able to confirm I had bought the correct belt size. I changed the belt and put it on center stand with the cover off the crankshaft case and revved her up and I could see the (I believe) clutch rattling really bad when first revving up (however the wheels were now spinning on centerstand). After giving it more throttle things would seem to tighten up and running smoothly (no more rattling) and wheels spinning fast. So I closed it back up thinking I had handled the problem and thought maybe the rattling was just due to no cover. I started it up (clutch still rattling badly) and it jerks bad and goes about 10MPH, I couldn't leave it at autozone so I thought f it and ride it home (no truck access) it turns out the clutch rattles horribly and it continues to jerk until it seems to catch and slowly but surely accelerates up to about 55-60MPH on the odometer with me on it. So the belt fixed my top end but in this whole situation it seems something malfunctioned in my clutch and now it has no low end until it just decides to catch itself (keep in mind only on FLATTTT ground) and accelerates normally and ridiculously smooth.
Sorry if that's too much info but I figure I'd like everyone know exactly what's going on so I can get some great input from all the vets to get this issue fixed and her back on the road.
Thanks again.. Jack

Hi all,
I wanted to update just in case anyone came into this problem. My top end speed problem is fixed, thanks to you all and your help! THANKS!
Added new air filter Complete oil change Cleaned spark plug Adjusted carbs air/fuel Ran some Seafoam through the crankcase and in the gas tank.
That fixed my power problem, however my blinkers and hazards are still out, I pulled the front cover off and disconnected my headlights and took a look around in there to see anything lose or out the norm and it all looks squared away however I don't see a round flasher (I just googled what they look like on our scoots). I checked all the connections under the seat just in case and followed the wiring as best as I could. Is there anywhere else a flasher could be put? The bike pictured above is truely a replica of mine, color and all lol.

Hi all,
I have been messing around with my scoot and have gotten it running better, today while I was adjusting the carb air/fuel my turn signals and hazards stopped working randomly, everything else works, headlights brakelights and horn. They are not blinking on the dash either, the switch and hazard button feels normal, I pushed it off the center stand to test out my adjustments and went for a ride and noticed they weren't working but the previous ride I took they were which was about 30 minutes prior. I doubt it is the bulbs since they all stopped working at the same time, I checked the fuse by the battery and it looks good. I think something came loose but not quite sure if I need to take the plastics off to check if they are all good to go. Any suggestions? I'm not familiar with the wiring on these things either but I learn quickly.
Update on jerking, it got better after my first adjustment then I adjusted it again and it got worse as far as top end speed and when it jerks. I changed the oil and got some seafoam in her crankcase, I will be adding seafoam to her fuel tomorrow morning. I will also fiddle some more with the adjustment to see if I cannot get it just right.

Will be doing that as well once I get this adjusting done. Appreciate all the advice! Thanks
Jack
edit-
While we are at it, I plan to replace all the hoses with the blue and green type from partsforscooters.com (Helix I believe) but I'm not sure which size I should be going for, does each specific part have a different size or is it more like one size fits all per type of engine? Any input would be appreciated, tomorrow I'm going to get into the carb and figure I'll take a look at all the hoses and clamps to see if everything is squared away.

Ok so I bought the air filter and installed it, I noticed when I removed everything in the air box there was some puddles of oil, the guy at the shop said it was spitting oil back up and probably caused the last air filter to become soaked and was probably why it wasn't there. I cleaned the box and checked the oil, I noticed it covered all the X's on the dipstick plus about half a inch which may explain why it's leaking oil? I tried to follow the oil and it kind of makes sense, it's dripping all over and made a puddle on some plastics by the fan on the bottom and is dripping from there. Well I removed all the oil and cleaned the filter and put in roughly 27-30OZ its half way up on the dipstick now. Seems to have more power behind her now but she is still jerky but now around mid 40's and upper. I can tell the scooter is feeling better from the changes but now I think I need to adjust the fuel air as suggested but I'm a bit cautious cause I'm new to this I wanted to try all the "easier" things first. Any input from anyone on what else it could possibly be besides the air fuel ratio being off? After reading a post on here I noticed people talking about a Japanese carb starting with a H but I can't recall the exact name, well it has that with all the original markings as Alley suggested and a spare used NGK spark plug so I think someone else took the time and maybe lost interest. The gentleman I bought it from said he paid 180$ to have the carb rebuilt while he owned it (he owned it approx. 9 months) so I think it wont be a huge repair. I just have to continue familiarizing myself with the thing. I'll keep this updated just in case anyone else runs in the same problem.
The oil is dripping mostly after running for long periods, since cleaning the air box and getting rid of the oil in there it hasn't leaked that I've noticed, I ran it for about an hour after changing the oil and cleaning the box.

It is right in front of the motor actually, will post some pictures tomorrow of my situation! Awesome to see knowledgeable people still exist on the internet! I'll definitely read the tuning thread tonight and sleep on it.
Thanks again for the knowledge.

That's awesome such a fast response. Going to buy one tomorrow and hopefully fixes my power problem. Once that's handled then onto the oil..
Thanks Alley

Also with the air filter, I am going to go to auto zone tomorrow, I don't have the money to drop for a KN filter that the auto zone rep referred me to, anyone know what I should be asking for as far as size wise? I've looked at a scooter parts website and have gotten the measurements of stock ones they are selling and plan on taking them into autozone and checking to see if I can't grab one.
Thanks again.
Jack

Hey all,
I just bought a used 2008 Chaun (according to the title) 150cc but the plastics say Adventure Limited Edition and lb150t-12. I thought it was a bargain but it may be more than I bargained for, there are a couple of kinks I need to work out. I am new these bikes so I want to get others input on the possibilities. I'm not sure if this has anything to do with it but the day I bought the bike I put unleaded in it (habitual, haven't rode one of these in years) and it requires 91 octane. I've been through about 1 1/2 tanks of premium since and the problem is still there however it has gotten better, it use to lose power around 30-35 now it does it around 40-45MPH. I took a look at the air filter compartment today to find no air filter, any reasoning behind that I may not know about or just lack of care? It jumps right up to 40 and I can stay there consistently but if I give it anymore throttle I feel it lose power/jerks then puts me down to maybe 37 then back up to 40 continuously, it does this through the entire throttle whether I'm at full throttle or not. There is some liquid in the air compartment but I see there are mesh screens so I figure those are there to catch liquid and this may just be excess. It also does drip a couple of drops of oil but it seems to be at random... I checked to see if mostly everything I could reach is tight and secured and it seems to be, I believe the electric choke was unplugged but I plugged it back in and it has seemed to help with a starting problem I was having, I was also having trouble idling at stop lights and I have adjusted the idle and it works pretty good.
Any help and input would be appreciated! Can't wait to see what you guys think and thanks in advance.
Jack
