|I replaced the K&N air filter with the stock air filter and ran redline fuel injector cleaner thru the system. New result is 157.87 hp @ 92.61 ft/lbs. (higher ambient temp /lower humidity) When I changed the filter, the idle dropped, and I had to adjust the idle up to keep it running. I would think this is more restriction? The dyno shows the bike is now running richer than with the K&N filter, but producing more power?? People have suggested dyno tuning the bike, I wanted to get yor input before doing this.|
|I am about to order one of your rear sprockets for a Hayabusa and want to know what size teeth should I go with that would not effect my top-end. I am already down one in the front. The bike will be used for quarter mile 10% of the time and the rest will be road racing on the highways. I have your 1397 kit!|
