Well I cancelled my order for the bbk, they didn't have a part in. I bought a Naraku bbk and a performance cam from a different supplier. Went through partsforscooters Here is the performance cam I'm going to use www.partsforscooters.com/Performance_cam_qmbAnd here is the 47mm naraku kit I plan on putting in www.partsforscooters.com/137-13-Naraku-Cylinder-KitI may need to buy another set of sliders. I originally purchased Dr pulley 5.5g sliders which should give me plenty take off but the top end would suffer. |

Well I talked to partsforscooters directly. They helped me out. Got a 72cc bbk coming and a new cam, with a 20mm carb as well. Thanks guys. Hopefully this bit does some justice. Oh yeah. I also Got an airpod/airfilter and some jets for rejetting. I'll be installing this all at once. Along with the 5.5g sliders. I'm sure over time I'll opt for heavier ones, or might just choose to keep stock in.

I need help again guys. The stock intake manifold....I don't think it's gonna work with with the 20mm carb I got. And the intake manifold I have seems like it has 2 valves. Would anyone know where to get a quality intake manifold with 2 valves for my gy6 qma?

Can you post a pic of the intake with valves? Usually the intake for these is essentially a tube with a flange on one end for connection to the head and a rubber clamped section for the carb. Most of the time a stock intake works OK with a 20mm carb, but if you go with some different style of carburetor then it may not.

Something else you may want to check is your current gear ratio. I'm assuming it's 13.5 like every other one I've seen. And if that's the case, you might want to get a 49/17 upgear kit, will give you a 9.36 final and 50 plus mph will be a breeze. |

Everything is still stock as far as cvt and displacement. I've included a pic of the parts I got. I will post a picture of the carb on the bike as well to see if that may help     |

I was told by a mechanic be careful with parts cause it could blow up the motor. So far this is the camshaft I'm putting in www.partsforscooters.com/Performance_cam_qmbI need to find a gear-up kit like you mentioned. Just don't want to match up the wrong parts. Hitting 50 would be great!!! If you know of a gear-up kit please share. I'll continue to look though. Gy6 50cc 139qma |

When you say the intake has 2 valves, do you mean ports or nipples by any chance? Not trying to play semantics here, I was just a bit lost when you first said that. If so, even if you just have 1 vacuum port on a replacement/performance intake you can put a tee inline and connect 2 things.
You can definitely cause harm to the engine with mods. Doing things wrong is a big risk, but there's a lot of info and how-tos so someone willing to take their time should be OK there. 50mm and larger bores are also a potential risk. There's all sorts of stuff that could go wrong, but again much of it can be avoided with research and help.

Right. I am continuing to do more. Which is why I didn't go for a 50mm. I was reading that could cause overheating issues if proper things aren't done first. I just wanted a little more take off. well. Nipples. But they are on 2 different sides
