No performance past 5k RPM
Bought this bike in June, knowing it needed a little love. Turns out it needed a lot more love than I expected. I've replaced: wiring harness, battery, R&R, front brakes, key ignition, junction box. Just when I thought I had everything running, bike broke down on trip to NY from DC. The way it was acting I assumed it was carb related (last thing I haven't touched). After pulling the carbs decided to also perform the ear shave procedure. After finding nothing wrong with the carbs I checked the gas in the tank and it turns out I had bad gas (water in the gas) from a mom & pop gas station that I stopped by on my trip.
The ear shave went off without a hitch. Airbox removed, K&N fliters installed, I cleaned the carbs while I had them off (and re-jetted per the instructions). Shimmed the needles, etc. Re-assembled everything. Bike starts great, tweaked the air/fuel mixture needles since I don't have stock exhaust and it was burning a little lean.
Now, when I get out on the road, in fifth gear, I can open the throttle all the way and get no response. It's hard to get the bike much past 65 MPH/5K RPM. This saddens me since I ride on the highway a lot. I'm not sure exactly what needs to be addressed or fixed. It appears the air/fuel screw is really only for the pilot jet, and this is a problem with the main jet. I can't tell if maybe it's getting too much air during high speeds and not enough gas?
I'm really not sure how to proceed and I can't reverse the procedure since the airbox was cut for removal.
