I assume your saying you have fattys and stock carbs on now. If so a 330 27.5 pilot 4 clip from the top. Would be pretty close. Quote
Mattsv8 Posted September 5, 2012 Author Report Posted September 5, 2012 Wow 330s I've read some saying 300s were too much for fattys. What percenage for oil mix. I know more oil leans it and less richens it too. Do u guys go for 30:1 32:1 I think I did it for 32:1. Mine does have a 4 mil stroke kit so I'm shure it wants a little more. Quote

Mine does have a 4 mil stroke kit so I'm shure it wants a little more. i have a set of keihn pwk 38mm carbs with kan pods. could i use these instead of the stock 28mm. the motor is 4mil stroke and 66.5mm piston. not shure on any aftermarket dome but its a stock head. it had a vitos monoblock cyl and head with 19cc domes and drag pipes setup for drag racing. at that time it had 68.5 mm pisons. right now its just stock cyl head i believe stock compression dome. 66.5mm pistons 4mil stroker short rod. and fmf fattys powercore silencers. stock air box with lid stock single filter. the pwks have pods that fit them and run with no lid. what should i do. right know its lean up top falls flat.

shakar Posted September 6, 2012 Report Posted September 6, 2012 if your riding trails, id stick with your stock carbs @ 330m -27 1/2 p like stated above .. big carbs will take some of the low end power .goodluck Quote
Mattsv8 Posted September 6, 2012 Author Report Posted September 6, 2012 Man that sucks these carbs look sick. The stock ones hd the tors eleminated and are twist throttle. Ill have to pull the stockers off and see what they are inside. I figured the 4mil and slightly more bore would like the pwks. I do a little idle but mostly like hairscramble. Speed and hills. Quote
Mattsv8 Posted September 6, 2012 Author Report Posted September 6, 2012 Where is the best place to buy the jets and pilot jets? Ill proably need a few diff sizes since I ride in diff weather. Quote
Mattsv8 Posted September 9, 2012 Author Report Posted September 9, 2012 ok i ordered jets from 290 to 330 and pilot jets from 45 to 47.5 for the stock carbs im proably gona get some 69mm pistons and run the vitos monoblock and head combo with the pwk 38s. what jetting for them would u use. looks like he was lean bad from the pistons that he had with it. the pwk 38s are 175 main jets and 45 pilot also have a set of 52s as they sit now. i was thinking about ordering 10 bigger and get 185s to 190s and use the 52 pilots.
