I want to know how much horse power I am getting if I have a 690 kit from curtis sparks with a 39mm fcr carb,hi rev cam,12:5 to 1 comp.piston,sparks exhaust system,port and polished, and a pro flow air kit??? [img]i/expressions/face-icon-small-confused.gif[/img]

 

your gonna have to go to a dyno. Nobody can answer that acurattly. Jetting plays a big part. Sorry

 

what's the stock 660R hp?

what's likely to show with intake, exhaust,cam,jets?

 

i wounder what a stock shee runs
Cuz the RZ is sapose to have about 10 more then that stock

 

whats an rz350? dirtbike??

 

probably some where in the 60+ h.p area would be my guess with the correct jetting!

 

My 686 is pretty close to the same build and I made 67.10 on the dyno. I'd say the Sparks kit would make 60, give er take a couple.

An RZ350 is a street bike
