Bunny771 Posted July 26, 2006 Report Share Posted July 26, 2006 Hey, Recently i messed up my carbs and am looking to get new ones. I was looking at keihin and then i found keihin style for cheaper. I was wondering if anyone knew anything about these. They are quite a bit cheaper so i wasnt too sure if they were as effective or not. Thanks Keihin Style Carbs Quote Link to comment Share on other sites More sharing options...

jbooker82 Posted July 27, 2006 Report Share Posted July 27, 2006 Those look like PWK 28mm carbs. Keihins web page doesnt show a 30mm PWK. The 28mm PWK's looks like they have the carb cap held on by screws while the other carbs have the screw on carb caps or tops. Keihin PWK LINK Other size PWK's I have the older desinged PJ34 mm carbs on my banshee. They work great. I am happy with them. The jets are numbered differently though. I am at a 155 Keihin Main jet with 58 Keihin Pilot jet. It isnt that hard to figure out though. Just thought i would point that out so you knew.

dajogejr Posted July 28, 2006 Report Share Posted July 28, 2006 Good eye. It does say Keihin Style.... Call a builder here, or look for a set of REAL Keihin carbs. Kehin or Mikunis will be just fine. What's more important is what size...and that's based on your mods or future plans for mods. I wouldn't trust the jetting on any "Pre-Jetted" carb. I'd do some serious research on some forums, find a few members who have similar mods to you, and ride in similar temps and elevation...and gauge your starting point from there.... No one can ever tell you the exact jetting you'll need. But...there are plenty that can get you close enough to start. Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted July 28, 2006 Report Share Posted July 28, 2006 keihin are good carbs. can be a little troublesome to tune sometimes but once they are tuned they are great. Quote Link to comment Share on other sites More sharing options...
BillyRay Posted July 28, 2006 Report Share Posted July 28, 2006 I run Keihin PWK 35 Airstrikers on my Banshee 426 stroker with dune port, shaved head, airbox removed with K&N's and Outerwears. Main jets =158, pilots = 58, needles in 4th position, elevation at 1,000 feet 80 to 90 degree air temp. Main jets may be a little fat, could probabally run 155's. Carbs work great. Had to install a Pingel valve though for more fuel flow. Quote Link to comment Share on other sites More sharing options...

dajogejr Posted July 29, 2006 Report Share Posted July 29, 2006 I run CELs in my 4 mil cub. They seem to be the favorite choice, unless you're WAY up there like Big Red.... Quote Link to comment Share on other sites More sharing options...
