i just recently bought a 1997 f3 for 500 bux, it already has a full yoshi exhaust from the header to the pipe, i was wondering about what kind of power do i have now and what would i have if i put a kn filter in with the jet ket, also the bike has a 14 front sprocket with the stock rear thanks

 

umm maybe 80hp

and yes a full exhaust will need rejetted. The air filter is personal perference.

 

u talking about to the tire? what are they stock?

 

also i was told the the se models make more power? is the color scheme the only difference? mine was purple and yellow im guessing making it the se model

 

They only made the SJE in 96/98, so yours is not one. If you had an SJE you'd likely know it. They really stand out and they've got a smoking camel on them. lol
