crazymx511 Posted May 23, 2004 Report Share Posted May 23, 2004 I just bought some 30mm keihin pwk carbs, they are 28mm that was bored to 30mm. Is anyone running these and could tell me a good place to start with the jetting? It will be awhile before my quad is all back together, so I was looking for someone else that has ran these carbs and could tell me some settings, before I get to putting the carbs on. My quad has the following, LRD pipes LRD mx porting 17cc domes K&N filter with no air box lid +4 degree key I race at 800' above sea level With stock carbs I ran a LRD needle 3rd clip, 350 main jet, 30 pilot jet. Thanks for any help! Quote Link to comment Share on other sites More sharing options...

tats4life Posted May 25, 2004 Report Share Posted May 25, 2004 the carbs came from Carb Parts, but I've had them for years. I used to run a JJH needle with pc's now that i have built it up i switched to N68A needles and now those needles don't work with my porting.
