Low and midrange problem?


Recommended Posts

or any site sponsor should have them. id recommend redline racing. if the previous owner had pipes reeds and after market filter and didnt rejet to what it should be then thats bad. you could be super lean and chance blowing up the motor. make sure you see what jets are in there first.  if your under 2000ft elevation then a good starting point would be 280 mains and 30 pilots needle mid clip in stock carbs, 1.5 turns out on air screw and see how it runs. you are running a air box right? and no lid?

I just tuned my 02 this weekend.

I'm at sea level.

T5's, Chariot Reeds, Chariot Intakes, +4* on the plate and I run 36:1 w/91 octane.

Stk carbs w/pods and no TORS

27.5 pilots

air screw 1.5 turns out

stk needle middle cllp

300 mains

 

You are right, 30 pilots, but I'd bump up the mains to 300.

280's might be too lean for VF4's and FMF pipes.

 

I did a plug chop and it was perfect, but barely...

 

Probably can go up to a 310 main, but I'm gonna rock it as is.

If it burns down, which I doubt, then it's time for a new top end and an aggressive MX port job!

I have the K&N filter in the air box with the K&N air box cover,it's warm now but fall is pretty cool up here between 3 and 15 C I will try your setup for sure and will let you guys know what happens.
