new exhaust-need rejetted? western pa area
Posted September 18, 2002 - 05:18 AM
getting powerbomb header, and just bought a powercore IV muffler with spark arrestor.
will i need to rejet my ride once i install these?
i live in butler , western pa. (45 min. from pittsburgh)
guy i'm buying the header off of is local, and said he didn't need to rejet (only had header with stock yzf pipe on his 00 426), so not too worried bout header, just canister.
any help is appreciated. i have stock jetting now, no airbox lid, no throttle stop, stock yzf muffler (currently) and it's running good. backfires a little, but not bad.

i'm gonna see how it runs with stock jetting, and if it doesn't run right/better than with stock pipe, then i'll look at rejetting. i been using top end a lot latley. feeling i'll be able to tell.
heck, my bike is probably jetted wrong to begin with. as far as i know, it's stock wr jetting, but i'm running a yzf pipe (higher flow?)
