Jetting For A Stroker

[JasonGOSU]

I need some help for a starting point for jetting. 4mm stroker, ported, 19cc domes, stock reeds, 26mm carbs, T-5's, Dual K&N, 4 degrees advance. Thanks for your input.

With 28mm carbs I was running 390's for mains with the stroker. Jason ran 380's I believe with stock carbs. Start the needle in the middle and adjust as necessary. 25 or 27.5 pilot should be fine.

Agreed, I had a 380 main w/ the mid pipes..I'd start around a 400 mains for the T5's. stock or 27.5 pilots, needles either 2nd clip or all the way down, so the clip closest to the blunt end....You won't use much potential of the stroker w/o changing the WHOLE intake from the box to the motor....Larger intake boots, carbs, reed cages, etc...You'll see huge gains and throttle response...
