Just wanted to share my experience with a new F Zero and the BT 80 drivetrain I installed. And then a tech question.
I transferred the BT-80 from a Huffy because I wanted more 'bike' under me, and the F Zero is that. The engine fit fine, but there was no way to make the pedal cranks wide enough to operate the bicycle part. So I shot a bolt through a crank arm and into the frame -- now I have 'pedal pegs'...my legs are offset, one up one back, but I don't find it uncomfortable. The banana seat was, so I replaced it with a big fat Schwinn seat and what a difference in ride. I am 5'10' 180 so the bike is a bit small, but not a problem. It handles like a small motorcycle with the 2.5 inch Hookworm tires. With the just broken-in BT 80, it cruises at 30mph and I've touched 36mph on my gps speedometer. Springer forks help absorb potholes, etc. I have the itch to keep working on the bike, modifying the engine, but have found that very few aftermarket parts fit the engine. I've tried 2 chambers/silencers and they don't match up to the manifold. You can't put on a hi performance head. I am happy with the performance, just want to keep tinkering. I haven't heard good things about hi-po carbs, but I was able to add a free flow airfilter. Runs a bit better at speed. NGK plug helped also. The BT 80 is electric start and pull start.
I can't get the electric start to work. It just goes click. All connections are tight, the LiPO battery is 13 volts, the engine ground is on bare metal. I tried jumping the solenoid, but nothing happened, so I replaced the solenoid, same result. You can get stock parts for the BT 80, so I replaced the starter. Click. I've just now ordered a new switch assembly, hopefully that's what is wrong. Anyone had the same experience? Happy to be part of the forum and willing to answer any questions about this build.
