Hello! I am 15 years old and i have just bought my first scooter. I am a big car guy and i plan on using the scooter mostly for when my car is broken or when i just wanna take a little spin for fun. The scooter i bought is a Baccio 50cc 2 stroke. What would you guys recommend for some first BUDGET performance mods? (i would like to keep the powerband fairly low for wheelies also) Thanks!

Well since you said "BUDGET", I'd start with this : www.scootertuning.ca/en/subframe-crankcase/11034-complete-engine-malossi-rc-one-94cc-minarelli.html?search_query=malossi+rc&results=630Actually, since you want something for a budget and without a high RPM powerband you could consider a sport 70cc big bore kit. With the stock pipe, power delivery can feel somewhat similar to stock, just more of it. If you want more later, then a good tuned pipe will raise the RPM for peak power and you'll lose a lot of the low end... but you can have big gains on peak power. With CVT tuning you can make use of that power up high and still do wheelies and such. You will need a selection of main jets with the big bore kit and you will at least need to change roller weights or switch to sliders. Clutch springs will probably get you off the line better. While you're doing this, clean and inspect the entire CVT. www.youtube.com/watch?v=2EjW-iSP-Q8 |

Yeah, if you just want a wheelie machine do a kit and tune the transmission. Assuming the stock pipe isn't a catalytic converter style.

Also any big bore kit recommendations? I would not like to go Chinese but like i said i am 15 and ballin on a budget. Thanks again for the help! |

You'll need to figure out what size wrist pin you have to help choose a kit. 49ccscoot.proboards.com/thread/2422/minarelli-1e40qmb-wrist-pin-sizesI've used generic clutch springs, the stuff that comes in blue (1000RPM), yellow (1500RPM) and red (2000RPM) kits pretty successfully. I tend to buy all of those and try each to see which actually works best for me. |

This would be a good CYLINDER for a beginner to learn with. It is cast iron, forgiving if you get it a little too lean and on sale at this time. If it is beyond your budget let us know and we will try to find something cheaper for you. Since you are keeping the stock pipe for now, you will not need stiffer clutch springs. Stiffer clutch springs will not give you "more instant power" stiffer clutch springs would likely make your launch worse. Stiffer clutch springs are used when you have a tuned pipe and need to bypass the poor low end a tuned pipe creates. As others have recommended get some main jets for your carb, you will need them. And definitely use the link admin provided and go through your CVT. You can do it for $0 now. That way you can see if you need a new belt, or rollers or something else BEFORE you order your 70cc. |

I read a small amount into finding the wrist pin size and that looks like a handful for me, as until my car is back on the road the scooter is my daily to school, work and back. If i find the model of my motor and look it up will it tell me the wrist pin size? |

Thanks so much, that cylinder kit you linked is a good price and looks like exactly what i am looking for, as i do not want to go Chinese and i am not looking to spend $250. I think i am going to pull apart and service the transmission for now and just learn and get a feel for (wheelies) the scooter before i buy the bore kit. Please correct me if i am wrong but wont 1500 or 2000 rpm springs give me a bigger launch for wheelies from a stand still? I really appreciate your help so thanks again! |

Well, clutch (and contra) springs are a cheap mod and fairly easy to try so go for it! CVT tuning is a PITA but it is also where you can find plenty of xtra performance if you stick with it. As Admin said you really need to find out what size wrist pin you have before you order a BBK. |

Looking up the engine code won't help in most cases. If you get lucky someone will know for sure what that make/model/year has.

thewheelie kid...I have seen some here. The Baccio VX50 is a 40QMB engine. Most Yamaha Jog Minarelli's 50's have a "1E40QMB" engine number. The Chinese versions use "1PE40QMB". I think Baccio last model year was 2013. The wrist pin (piston pin) size being discussed can be either a 10mm or a 12mm on those engines. The easiest way and sure way, is to pull off the cylinder and measure the pin diameter. It would cost you 2 gaskets and an hour or so. (Many of us make our own, should be templates on the "templates" page.) It is good experience!  The green gasket is the cylinder base gasket and the copper one is between cylinder and head.
I have mentioned before: Cleaning and tuning will net you performance. It takes time, but worth every minute. Even just cleaning the unburned 2 stroke goo out of the pipe will allow your engine to breathe. Best time to do it is when you pull the cylinder. The pipe must come off anyway. We do ours annually, if not more often.

I’ve never run the base Stage6 kit but am a fan of both the Malossi and Polini basic sport 70cc cast iron kits. Ain’t got no real data to support this but seat of the pants running the same pipe on both I’d say the Malossi has more on the bottom, the Polini has more on the top.
Doesn’t help this situation at all. Vespa moped engines can be 10 or 12 mm pin. Treats sells a kit that comes with both pistons for people who are too lazy to check ahead of time.
Friend of mine put the wrong contra spring in his rear pulley once, it was an unknown that was laying around the shop, he figured it was worth experimenting. He wanted more off the line because I was killing him on launch with a stock TGB and he was running a kit and pipe. It definitely wasn’t meant for a Buddy 50, damn near locked out the variator it was too long I think. Made the bike want to stay on one wheel, but wouldn’t go over 30 mph. That’s an extreme but demonstrates the difference transmission tuning can make.
It’s hard to beat a TGB off the line, they’re geared for pulling stumps.
