I have a 98 warrior with a k and n filter and full cobra exhaust... Dyno jet says to use a 136.... What is the mikuni equivilent jet? Thanks

 

i have a k&n filter as well but a white brothers e-series exausht and i run a 150 main jet. the 136 is well under stock useually you would go bigger on the main jet after putting a pipe on plus having the k&n filter.

jetting can also be a pain in the *** sometimes it's something you have to play around with.

 

I didn't memorize the dynojet to mikuni chart, but your best jetting will most likely be a 150, depending on your conditions (altitude, temperature, etc) you may need to go to a 147.5 or a 152.
