If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

Keihin CR Carbs??

Hi, I was under the impression that KEIHIN CR CARBS were similar to Mikuni RS Flatslides (with accelerator pump). Now I've heard they are not. Would the 35 mm CR's be a good choice for my 1100E? Are jets redily available for them? I had been waiting for a set of Mkuni RS's. Thanks Very Much, Dave
 
Parts are generally readily available for aftermarket carbs. Trying to buy non standard parts is a nightmare for standard carbs.
 
Hey, Sundog,

I have an '81 GS750, and have gone from Mikuni CV (34mm) to Keihin CR smoothbores (check out Sudco.com...its where I bought mine. They have Mikuni smoothbores. Just follow the mikuni carb links from the homepage) I even screwed up and bought the wrong size; was too impatient to ship them back and get the right size. Misread the manual. Pre 81's had 26mm CV's, and said a good upgrade would be 29mm. So I kept 29mm smootbores. When I found out my mistake, I had a machinist buddy of mine machine a set of sleeves onto the carbs so that the plenum boots would fit right. (Even with the carbs being 5mm SMALLER than the stock CV carbs, it is a totally different machine. It is like a night and day different. The bike pulls hard all the way through the rev range, especially starting about 5500/6000rpm's. MThe smoothbores elimininated the the airbox(uses K&N pod filters) and also had to convert to a dual throttle cable system( 1 cable pulls the throttle open the other pushes it closed--not hard to install. ) Call Sudco and talk to them, see what they recommend. I called them and their tech guys were all pretty cool. One of the salesmen (with a british/scottish/irish accent) did get a little argumentative, but not that bad. Hope this helps you decide!!

Sundog, I goofed. I got Keihins from Sudco (went through a dealer, though). They sell both keihins and mikuni smoothbores. They sell carb manuals too. Good luck!!
