Was wondering what you guys think, 351 kit with stock carb 2500 to 4500 feet with usual mods( air box/filter, muffler, stock header...) . Thinking of running #38 pilot and 132 or 135 main (keihn jet).Also was going to put in a klx300r emulsion tube for jet needle (running n1tc already).
thx

Probably a good place to start. Sounds like it will be close.

 

What EMS said. I'm about 2500 ft, just installed 351 and first ride last weekend with #38 pilot and close to a #138 Keihin size. I think its rich on the main and will be trying a smaller size soon.

 

thx guys!hope your 351 kit went smooth ill be doing mine in a couple weeks I hope.

 

I run at your altitude and even higher at times (up to about 6000 ft).

I left the stock #35 in there and it runs great. For me, a #38 would be too rich.

I did go with the bigger main jet though, but that was for my Two Brothers pipe/airbox mods more than the 351 kit.

 

What main you running? DJ or keihn i run up to that elevation abit to so would be a good starting point for me.
thx

 

Dyno Jet, #128 I think. I'd have to check my notes for sure.
