OK i've been avoiding asking this question because I didn't want to sound dumb, but i'm now just too curious. I don't really get after my F2 all that much, just casual riding. When I do though, i've noticed a substantial powerband that kicks in at about 7-8k. It is neither subtle or smooth and, although embarrassing to say, catches me off guard if I forget about it. So I guess my question is, is this normal? Should it be a smoother transition than that, or is that how the F2's are?

 

The motor definately doesn't start generating real power until you're up above 6K or so, but I can't say that it resembles anything like an obvious powerband. Mine still accelerates smoothlyand predictably above that RPM.

 

Its normal--myF2 doesthe same thing (and so did my Hurricane).Feels like someone hit a nitrus button and I like it!! Most600'smaketheir peak HP uptop of the rev range.

 

if youre not the original owner, then theres a good chance the previous jetted it.....pipes? polished heads? new intake? fuel pump? dont worry, thats the FUN part of these bikes.....good to learn on and ROOOOOOOOOM for improvement when your nuts drop.
