This is weird. My Hyper is not running well. At 4500 rpm, the motor vibrates a lot. Other odd symptoms include intermittent hesitation when coming off the line and surging at low rpm, 1700-3000. The best way to describe the surging is this. If I am in second gear at a slow steady cruise, the bike almost sounds like it has a fouled plug. Imagine one cylinder firing consistently and the other firing intermittently. Basically runs like crap. Unless I am above 3K rpm in first, I have to feather the clutch because of the surging. The oil temp seems to have increased. Last night, cruising in San Jose, CA on the freeway, the oil temp was 230. It was cool, 64 degrees and I was running on a flat section of freeway approximately 65 mph. Typically, the bike would run 205 to 217.
When I first took delivery of the bike, it ran very hot, 250-280 constantly. Nichols Engineering found that the themistor plug was not connected properly and that brought the temperature down and resolved the CEL issue. The dealer told me not to worry unless the bike indicated "HI" on the display. Before that, I opted to replace the mid pipe thinking the heat source might have been the catalytic converter. That did help and gave me 3 hp according to the dyno. Also, in an effort to help cool the motor and richen the mixture in closed loop mode, I added the Fatduc. The Fatduc helped a ton. I also replaced the front sprocket with a 14 tooth hoping to raise low speed rpm making the bike easier to roll out of low speed corners.
Throwing money at a new $15K bike to make it run decent is getting old. Any of you Hyper owners had similar symptoms? Overall, I love riding the bike but hate this newly developed vibration, low speed surging and hesitation. It's not fun to ride like this. Could the problem be a flaky ECU? Can they be tested?
Thanks
