+1 to jeffjones with the bull**** call haha

 

Thats fine you can call bull**** ans yes the speedo is off by 8mph so enless the speedo get mor out of wack rhe faster I go. Wish some lived in central ohio so I can prove it ill video and post it.

 

What rpm does your bike redline at?
Because as I stated before unless you were at 17,000rpm your gearing proves it isn't true. Because in 5th gear with your set-up your bike will do 175mph @ 17,000rpm and at 134mph @ 13,000rpm.
You can say all you want but why is your F4 the only one that disregards the rules of mathematics?

You did not have a normally aspirated F4 at 178mph in 5th gear. Hell, you didn't have a normally aspirated F4 at 178mph in 6th gear. And by normally aspirated I mean no turbo, blower or nitrous. I don't care to see you do it on video ... I wanna see your dyno sheet after those runs. If you aren't pulling 140+ hp that bike isn't overcoming the wind resistance to make those numbers.

 

shoot my 954 with all stock parts has a max speed of 178.I want to swap my motor for your F4.

 

I wonder if he has a Canadian Speedo and those number he is hitting is km/hr

 

None of these F4's will hit 170 I don't care if they do have a pipe and jetting. Use GPS speed people your speedo's are way off even from the factory. My buddy topped out his F4I even though it said he was doing over 160, GPS max reading he got was 143. Post vid with GPS speed and I'll believe it.

 

Thats what I jumped too.

Wonder how often he has to service the engine hitting 17k rpms on the daily.
