curious as to how fast u guys got ur f2's...stock or whatever.,,,,

 

165, but speedo is very inaccurate at that speed.

K&N, stock pipe, -1,+2 gearing, 140lb rider.

 

I thought I had read that with stock gearing in the transmission, and the stock 15/43 sprockets @ 13,000 RPM in 6th gear top speed would be about 163.

-1/+2 would decrease that theoretical top end.

Course all of that depends on the bike actually being able to get to 13k rpm in 6th gear.

 

Looked it up on http://www.gearingcommander.com/

here's a chart they generate:

 

Bingo, stock F2 doesnt have the power to get to redline. the -1+2 gives it the oomph it needs to redline in 6th, so you don't actually lose top speed with this gearing change on this particular bike.

 

I've never gotten my f2 over 20 mph.








Wait, I don't have an f2.

 

It does. I've been there friends



There's not a cold chance in hell you did 165 with a -1 +2 setup, and even less of a chance you broke 150. I'm only running +2, and I topped by bike out (revlimiter in sixth) on the straight at PIR (Portland International Raceway) at 158 indicated.

 

142mph on my F2 streetfighter(Trailtech digital Vapor gauge), front end started lifting real bad. My bike is as aerodynamic as a billboard.

 

This isn't the first time that you have failed to read specifics in peoples posts. You may have a mental disorder that you should get checked out.

I said that the speedos are known to be very inaccurate. On top of that, no 2 bikes are the same, and no 2 riders are the same. How much do you weigh? I am 140 lbs, hell I was probably 130lbs when I was dumb enough to hit that speed on public roads years ago.

One of these days, maybe I will get a video to shut you up.

 

lol..you guys are crazy.....i'll post my top speed as soon as im up and running
