 So, I have a habit of making a post a few days, or hours before ordering parts. This has helped me in the past in getting you guys' opinions on the things I plan on ordering. I'm hoping I got everything I need this time, but I haven't placed the order yet and I'm just waiting to start next month's credit cycle so I get the full "6 months no interest" thingy. So, once again, I'm limited to Amazon.com and Newegg.com credit because I'm strapped for cash and will only be making enough money this weekend to pay on my credit card bills anyway. I wish I could get a high quality bbk from scrappy's or tvnacman's site, but I'm going to have to resort to the cheapo on Amazon because it's the easiest for me to order right now. I can probably allot $20 (noncredit) or so toward buying piston rings or some other thing if I have to, but I'm hoping I won't need to and that the rings that come with the bbk aren't horrible. This is my cart as it is right now: www.amazon.com/gp/product/B0019O6OCO/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A3PZ243HFH7051www.amazon.com/gp/product/B00AYRZJPU/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=A3M9NXSSW7AH0Ewww.amazon.com/gp/product/B000HDIP9I/ref=ox_sc_act_title_5?ie=UTF8&psc=1&smid=ATVPDKIKX0DERwww.amazon.com/gp/product/B000BYGIR4/ref=ox_sc_act_title_6?ie=UTF8&psc=1&smid=ATVPDKIKX0DERwww.amazon.com/gp/product/B00A2OJ5R8/ref=ox_sc_act_title_4?ie=UTF8&psc=1&smid=ABXFT02JRY7Land maaaybe this www.amazon.com/gp/product/B007PC821A/ref=gno_cart_title_1?ie=UTF8&psc=1&smid=A2VPA2J7YDDYSTIf you don't want to click all the links... I've got some digital calipers (to measure my current bore and measure other stuff), another set of feeler gauges because I lost mine, an iridium spark plug, a performance exhaust, and a 50mm BBK. What more could I possibly need to install the bbk? I have socket sets and lube, and oil and such. Do I need other parts to help my bike perform better? Will my stock carburetor work? I've got a  jet I plan on putting in there when I get the bbk. I've been looking at this Hoca piston: www.amazon.com/Hoca-139QMB-50mm-Piston-Kit/dp/B007PV9LQQ/ref=sr_1_3?ie=UTF8&qid=1369839146&sr=8-3&keywords=50mm+piston+scooterWould it be worth getting the whole piston if my rings turn out to be gapped too wide? And again, this will be my last order for a long time because of my current financial situation, if there's anything else you think I could possibly use to make my bike perform better please let me know. I'm currently at my $151 budget limit, but I may be able to squeeze in other items or substitute others. Thanks in advance for your input!

[replyingto=ej132]ej132[/replyingto]Well, I plan on getting the cheaper chinese bbk anyway, and while I would love to get tvnacman's bbk, I just can't see myself spending that kind of tall cash when the only difference I can see is that the part has a guarantee on the box because it has been tested.
As it is I have no choice in driving on main roads and driving my scooter everywhere I go. I have no choice but to drive on 45mph roads going barely 35mph. Do you know how scary that is?
I have over $1000 in credit right now, but I only have enough money to pay said credit bills, I feel I may as well use the credit to buy the parts that I need right now while I can, as my financial situation is only going to get worse from here on out. You may not understand, but this is going to be my last chance for a long time to spend this kind of money unless I spend this money.
The most optimistic outcome from this is that I will attain enough speed to travel to McHenry's industrial park and I'll finally be able to get a legitimate job rather than fixing people's computers for spending money. So, in the long run this may actually make me some money.
I'm going to get a bbk, and it's only a matter of time before I do so; I may as well do so soon while I have the opportunity. Even if it is the cheapest one I can find.
I got money set aside to get my L Class license, and yet I can't even get my L class license without being able to attain the speeds just required to reach the DMV! My scooter is impressive for a 49cc, but I need more power and I need it yesterday.
EDIT:
And my household can't be that desperate for cash, if my mom is smoking $6.99 worth of cigarettes per day ($207 a month) then I can afford to have my little hobby ;D

Some of those secret 60s are pretty quick, and most 100cc BBKs aren't actually 100cc's... A 50mm kit like you are looking at usually maxes out at right around 80cc's of actual displacement without a stroker. Also, as soon as you go the BBK rout there is a possibility that your reliability will also take a hit, so that cost is something to factor in as well. An 80cc kit sometimes can be "heck" (?! - We're censored?) on a stock crank and bearings causing early failure.
Most secret 60s that I've had my hands on can do about 40-45 with the proper transmission work: proper weights, springs and a good quality variator. Naturally this all depends on the rider. Anyway, just food for thought.

[replyingto=fugaziiv]fugaziiv[/replyingto]Thanks for the input, Matt. My secret 60 is pretty quick compared to most 50ccs, it just can't handle taking me up hills or maintain speeds over 40. My speedometer says I can reach up to 50mph downhill, and over 40mph on flat terrain, but according to GPS my scooter maxes out at 43mph downhill and about 38mph on flat terrain. I'm a bit overweight at 267lbs, but I'm working on that. I'm sure with losing the weight will come even more power, but until then I need a small increase in power, which is what this 80-something cc kit advertises. As Hank says, as long as I don't abuse the power I should be alright for quite a while. And as Millsc said, if my crankshaft goes then I just need to replace it. Would you recommend any particular safeguarding for failure down the line? This www.amazon.com/AVANTI-50cc-4-stroke-Crankshaft/dp/B0047PYQ0Y/ref=sr_1_3?ie=UTF8&qid=1369860517&sr=8-3&keywords=139qmb+crankshaft is what I planned on buying probably next year when I need it, unless I save up for an even higher quality one by then. |

Nope, so long as you are prepared for the inevitable repairs I don't have anything to add that could safeguard against failure. Although you are correct that if you can shave off a few lbs, that will help out a bit as well. The ScrappyDog crank looks as nice as any less expensive cranks that we have, so I can't recommend against it, although you might want to look at tossing a set of higher quality bearings on there if you go that way. Here is an example: www.partsforscooters.com/169-332-Hoca-QMB139-Bearing-Seal-Kit . There are a few people who offer similar kits, and any of the higher quality sets of bearings can take a bit more of a beating than most of the stock setups. I'd probably only spring for the HQ crank if you were also going to run a HQ top end... so maybe down the road? Anyways, good luck and don't pin it for too long at a time! Matt |

I really appreciate the input, Matt!
I tinker on my scooter for at least a half hour every single day, swapping weights, checking my belt, checking the oil, tire pressure, etc. so I'm pretty well prepared to perform whatever repair or maintenance it takes to keep my scooter going. I once had to repair my kickstarter on the side of the road because the c-clip had come loose, so roadside tinkering isn't out of the question either (I always travel with a toolbox in my trunk). ;D
I'll probably be buying those bearings you recommend some time as well. I want my scooter to last as long as possible, so I'm willing to buy whatever it takes to keep it on the road, but I'm also desperate for power and a sucker for cheap parts so it's a bit of a balancing act. As far as bearings go it's an excellent idea for me to swap my stock ones, and I'll definitely be doing it some time.
I'll make sure not to run WOT all the time. Right now I have to run WOT ALL the time, so I'm thinking the bbk may actually save my scooter in the extra long run. Kind of like how computer overclocking works.

[replyingto=lykos23]lykos23[/replyingto]I saw the the piston ring installer on your list of things to buy. My first BBK install is pending, and I'm just wondering how many of you use a tool to install the rings and how many just do it carefully by hand. Lykos, depending on the feedback, maybe that's an item you could cut out and save a few bucks. BTW have you considered jet sizes higher than yet? I think might be just fine, but going a little richer might be easier on your bearings. I'm not speaking from experience, just what I've heard from others on the forum. |

[replyingto=awhitlock]endru[/replyingto]That's a very good point, Endru. Perhaps it would be better to carefully place the rings by hand. I've never needed special tools for precariously delicate procedures in electronics I don't see why I should need them now. I've considered going higher in jet size, but I already have a # jet I ordered from previously when I was finding the right jet currently, so I figured I'd start with the and do plug chops and go from there. I didn't know it was easier on the bearings to use a larger jet though, that is very intriguing. I've added a performance fan to the list because in the computer environment proper cooling is key and while that doesn't correlate to the world of scooters it just seems like good juju to get the fan. It's only $20 anyway, haha. |

Well in that case, here's a video I found with a quick youtube search. I guess the key is not scratching the side of the piston and avoiding excessive stretching of the ring and possibly breaking it.
How to install piston rings by hand:

if you run the 100cc bbk wide open it will expire the engine so you will learn and have to start over.
Go for it.
All the rational means nothing if you miss the big picture.
but that's life so it doesn't matter either way.

[replyingto=awhitlock]endru[/replyingto]
Thanks, Endru! That video will sure to come in handy. I really appreciate not having to look for that, haha.
Whatchoo talkin' bout? What's going to expire? Why? How? The big picture is a collapsing economy, but that has nothing to do with this at all. You know that it's a 50mm bbk and not a full 100cc bbk, right? It's like 82cc. A 100cc bbk might make my engine explode, but 82cc will just shorten the life of my crankshaft from what I've heard.
If there's more to this, do tell.
