i have a yohsimura full exhuast system right now but i am thinking about getting a hmf slip on do you think the hmf slip on will make more power than my yosh or should i just stay with the yoshimura. thaks

 

I'd just keep the yoshi and get a k&n power up kit to help ur motor breath better.

What compression piston and what kind of cam do you have?

 

i have a 12to1 compressiton pitson and i think its midrange cam dont they brand name it was already put on befroe i got it

i have a k&n filter i just havent put it on what all comes with the power up kit

 

you get new springs,mains, a needle and a clip. the Dyno package is way better.

 

will i get any more power out of it

 

Keep the Yoshi

 

I put a dynojet kit on mine last week. Major power pickup. I also have a K&N, White Bros pipe, and i ground down the welds on the header pipe. I ended up going with the 170 main which was the biggest one they sent me. I also took the airbox lid off. Just my 2cents hope it helps.
