Hey!!! That's 67.2Km/h for mine! (right now, I'll take every last klik I can get!) LOL
I'm quite impressed with this thing. We installed my (unused) factory carb, airbox, muffler, and fuel tank. Rigged up my own breed of throttle (no governor) and had to spend some time getting everything fitted and aligned. Cut and installed some new chain, and crossed our fingers.
Lit up on the very first pull! Did a bit of throttle and carb tweaking, and away we went! Daddy did the shakedown run (for safety's sake) and then handed it over while I whipped out the trusty radar gun. A couple of calculations later, and it seems the boy was turning more than 6200RPM!!! Wow! I didn't expect those kind of numbers!
What I do know- stock carb, jet, intake, muffler, and flywheel. No governor (duh! LOL) Timing advanced by a few degrees- I pulled the flywheel off for inspection, and found the key to be filed down, although I didn't mic it.
What I do NOT know is what internal mods may have been done. Considering it's revving over 6000 with no valve flutter, I suspect some changes inside.
I also know she's running just a touch lean, so if it stops bloody raining, I'll open up the jet a size.
Go Son Go! (Just please don't kill yourself! Remember- if in ANY doubt, smack that kill switch!)
