65 MPH top speed at 7200 RPM 39 deg day

I would like to thank all the little people for this gracious award. It was just luck hitting the right combo on the setup. Carburetors aren't my specialty but do manage to tune them. My specialty is tuning fuel injected, turbo and supercharged engines with a computer. I did cheat a little. I stuck an O2 sensor down my exhaust pipe and hooked up an air/fuel ratio gauge to check my fuel mixture for WOT. Not the proper way to do it but looks like it worked good enough. My intent was to weld a bung in the exhaust to mount the O2 sensor. To get more out of it I would have to be able to advance the timing a little. I was looking at the adjustable CDI's but they just change when the timing is advanced and not increase the timing.
Give me time and I'll figure it out.

I played the B-flat Cornet. Maybe that tone reader is set up for concert "C". Trumpets, Cornets, Tenor Saxaphones are pitched at B-flat, concert scale. Concert scale is the same as a piano scale. If you strike the middle B-flat on a piano, you should be in tune with a trumpet with all valves open.

RPMs are wrong in the first pic (should be just over 8,000, not 13,000+), but top speed of 82.6 Miles Per Hour was verified with a Garmin GPS (showed 83 mph) and a 2009 Subaru follow car... that Bashan WILL has a Lifan 197cc engine and 17t front 39t rear sprockets... 120lb rider soaking wet complete with baggy clothes and riding gear creating huge amounts of aerodynamic issues might push a hair shy of 90 if I get some proper/smooooooth riding gear



And I also found this pic on my phone, it's from a while back... I think it was back when I had a 45t or 47t rear sprocket on the beast (trying a 43t right now) to do the 12,000+ foot CO Mountain climb ...

RPMs are wrong again, those are showing close to maxed out from a lower gear... I was probably being followed by some 5-0 that day and highway speeds was posted at 65 no top speed runs that day with the 64.9 mph showing (I was as close to the speed limit as I could get it Officer!)... I think top speed with that sprocket set up will be just over 72 with the RPMs screaming

120#???? you got that HP/weigh ratio way up there. I don't think I could convince my wife to let my 90# 16 year old daughter to go out and set a speed record lol. Nice results

Results are in......thanks to mjstef I received my new instrument cluster today and got it installed. Took the Hawk for a test spin and it showed 70mph at 8100 rpm. I was pleasantly surprised with that.
