Keihin Cr Special Carburetor Tuning Manually
Keihin CR 'Special' carbs- starter circuit info. Figured I'd post this in case anyone else has trouble getting a good idle to 1/4 throttle with their CR's. Now I FINALLY get to do some proper carb tuning. I have just put up the Keihin Troubleshooting Guide and the Keihin CR Owners Manual up for download. I have some jetting issues, and a guy said that there is something called a fuel screw on the carb that will allow me to make the bike richer or leaner. Ask the mxperts fuel mixture screw how.
Description
Wanna be faster than the retired history professor on his gentlemans T100? You gotta pony up to get those pony's out. You can expect to get approximately 10% increase in horsepower and precise throttle response.

So far, fantastic
A remarkable improvement in manufacturing quality, these carbs feel better on the bike already. Though they came pre-jetted for the predators and pod filters, but they'll need a little rejetting as I believe they're jetted for sea level. But even with the bike a little out of tune, the performance and general response is vastly improved. Absolutely zero regrets getting these puppies. So tuneable, so ahh!
