The BBK is some Taiwanese one I got off eBay, 80cc. Looks to be decent quality. I also have a Keli variator, YMS exhaust, stiffer clutch springs, and a 9.2:1 gearing kit to install. My understanding is that the gearing is more important than raw HP for better top speeds, but unfortunately, I don't have the equipment to re-gear this bike right now so I'm looking to install everything else first.
So my question is... should I install the BBK? The bike is totally de-restricted now with the exception of still running the 68 main jet. If I just up-jet, run the YMS exhaust, and install the new variator, what kind of speeds should I expect? I took the bike for a quick test run with just the new exhaust and hit an underwhelming 34MPH without re-jetting.
I'm looking to be able to cruise at 40-45 - would a Keli variator and a re-jet get me there? Or should I bite the bullet and put the BBK on? I'm a bit apprehensive on installing the BBK as I've heard there's quality concerns with these Taiwanese kits and I'd hate to damage an otherwise functional machine.
Thanks in advance for taking the time to read/reply!
