tats4life Posted May 14, 2004 Report Share Posted May 14, 2004 (edited) You need to talk to your porter and see if the motor will have enough velocity to run like it should with 34's. my duncan national motors were killer with 34 pj's, but sucked with 28's or 30's. The motor i have now is ported for 28's, but once i break it in and ride it for a while i plan on trying it with 34 pj's. If you get a 34 i recommend a 34 or 35 pwk, there soooooo much easier to tune than a pj. pm me your dyno sheet, i'd like to see it. banchetta's is a nice bell shape before he got a stroker. what's your set-up, i'll try to help an anyway i can. tat2 Edited May 14, 2004 by tats4life Quote Link to comment Share on other sites More sharing options...

MotulMonsta Posted May 16, 2004 Report Share Posted May 16, 2004 I'm running two 28mm pwk's, I pretty much have my motor built to the carbs. I don't know how much power my shee's making, but it's alot. The 28's arn't much bigger then the stock 26's but they are a hell of a lot better and way easy to tune. I like them..I've had them for years now and they work like a champ. Quote Link to comment Share on other sites More sharing options...
reas11 Posted May 16, 2004 Report Share Posted May 16, 2004 i'm running 30mm rs carbs i like them i have the portwork to go to a bigger carb, but actually in all honesty i'm satisfied with the lowend i get from using 30mm. and my pipes allow for the topend pull.. i think u should consider using rs carbs if u want the lowend and if u want more pull on top change your pipes up consider getting your flywheel lightned .. advancing your timing and porting your cages .. theres so many possibities u can do to increase your hp . right now my bike is nowhere near an mx bike but with my port, 30mmrs carbs , ported stock reed cages, timing advanced +4 deg. im at sea level and im right at a 370 main with the needle at the 3rd clip.. one thing to consider if u decide to get rs carbs is that u need a bigger pilot jet then u would with fs or ds carbs .
