Hi everyone...

I just bought a Chinese 66/80cc kit from Boygofast on E-bay. It hasn't arrived yet, but I was reading through some threads and thought I should register. This seems like the place to be if I run into any snags along the way .spr.

I'm kind of split on what I should hook it up to. I have a nice simple mountain bike...but, I really want to put it on a Ten-Speed to shave as much weight as possible...and I also think a ten-speed would kick ass with a shift kit later on. Any advice or even general ideas are welcome.

I'll take some pics of my build and will probably be asking for advice.....till then, happy riding reddd

I haven't put a kit on a ten speed, but I have put them on a lightweight single speed with no problems. A mountain bike will be more robusto, but if you ride like a sane man, the 10 speed will be fine.

Be aware that BGF has been proven to be problematic in the recent past if you need service.

Re: First time MB'er

A frame mounted engine can damage your rear wheel if the sprocket is installed incorrectly, chain adjustment is way off, spokes are too loose/tight, etc. I'd do the mountain bike, with the stronger wheels on a first build. Cheers

Re: First time MB'er

Thanks for he warm welcome guys ;)

You have a good Wheelbender6...thank you. I think I will start with my mountain bike.

Bikeguy Joe, could you elaborate on BGF's poor service? Do you mean obtaining parts, or just customer service in general? (like troubleshooting)

Re: First time MB'er

Welcome to the forum!

As far as BGF goes, I think it's a hit or miss kind of deal. I got a pull start from them and got lucky, but I was willing to take the risk, even after reviewing their feedback ratings. Now that I've been here and gotten to know of much more reputable dealers, I don't have to take chances like that again!

But yeah, you are taking a chance with them.....you may be lucky, and you may be just another embittered customer!

Let us know how it goes.

Re: First time MB'er

Got the kit, it wasn't advertised as so, but, it's a Red Bat...it was in great working order but, when I got home I noticed that the rear studs have broken off at the block. :-||
I should of took the advice in the other thread about changing the cheap hardware...oh well, it was fun today, now I gotta see about getting some vice grips on the studs....wish me luck...I don't want to have to tap em out!!!

Update::

Got the studs out, was a little off so I up sized to 8mm studs, it worked well.
But, now I am having an issue with top speed. When I floor it it winds up, then bogs back down?
I am running a 16:1 fuel/oil ratio....checked the cylinder walls just to make sure...no visible wear, swapped plug, not fouled out so next I'm going to rebuild carb and check the points

Update 2::

Alright all fixed up and running...yay!!!
