MarineNYC Posted July 16, 2007 Report Share Posted July 16, 2007 I am running a set of stock carbs right now. I continue to have constant problems with them and I am getting fet up. I was considering upgrading to bigger carbs. If I do so what size do u recommend for a casual rider. What other parts do I need other than the carbs themself (Like boots and stuff?). And how much will this thing cost me? Quote Link to comment Share on other sites More sharing options...
badassbanshee479 Posted July 16, 2007 Report Share Posted July 16, 2007 any engine mods?? 30-33 pwks seem to work well for stock bikes. I ran a set of 35s in my stock boots, but I had to grind them out to make them fit. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted July 16, 2007 Report Share Posted July 16, 2007 I ran Keihin PWK 33's on my mx ported machine. I now run them on my drag ported 4mill. I woulnt waste my time on 28-30mm knock off brands. Quote Link to comment Share on other sites More sharing options...

locogato11283 Posted July 17, 2007 Report Share Posted July 17, 2007 im with you, i never cared much for stock carbs either. i thought they were a pain. i would go with some keihin 30mm pwk. they will work well with your stock motor and will be good with some porting as well. youll need to buy some upp or other intake boots to go with them.. i would recommend calling jeff at FAST. he will set you up with everything you need at good prices.. give him a call. 1-785-364-5325 Quote Link to comment Share on other sites More sharing options...

I woulnt waste my time on 28-30mm knock off brands. Not sure I agree with that. I havent ran any bigger than 30mm knock offs. They definitely made a difference over the stockers. Unless you've run 28-30mm carbs I guess you cant say either. Quote Link to comment Share on other sites More sharing options...

He told me that if I was just going to stick with pipes, reeds and cool head that the 28-30's would be ok. He told me if I plan on porting my banshee (wich it had already been done) to go with the 33's Quote Link to comment Share on other sites More sharing options...
