do i have to?

[J-man2002]

would i need to re-jet my yz 85 if im putting on a new fatty pipe and reeds?

 

[Rich Rohrich]

Yes.

 

[J-man2002]

what size's would i need for riding in temps ranging from 5C to 25C?

 

[Rich Rohrich]

No idea. You have to jet it, which means YOU have to figure out what changes are required. Welcome to the exciting world of high performance. ;)

Streamers & stickers are much easier to deal with, no jetting required.

yeah a pipe is not worth the money i noticed a minimal increase in power all arounfd with the fmf fatty and a shorty pipe. and yes i correctly jetted it for altitude and heat as well

pipes arent made add power all around. they are designed to make power in different areas and move around the powerband.

Actually the main objective of most all of the main brand exhaust systems is to lighten.... your wallet. Most of the "performance" if superficial bling that makes ya' feel like it's faster because you spent all this money and the advertisements says it's going to do it.

I'd be suprised of most folks that installed one of these systems did little more than adjust the external adjustments on the carb and maybe a smaller number might adjust the needle clip.

Patman gave you great advice, save yer nickels. Make sure your bike is jetted for your current setup...I'd bet money it isn't.

yeah, sounds like a good idea, i need to stop wasting money
