Before I touch anything, I wanted to get some advice. I bought a 03 660 ( has a slip on pipe, k&n air filter and no air box lid) from a guy who I would say knows his stuff. Here are my symptoms.
1. When I'm riding in 1st gear bike runs fine. when I shift to second and slowly run on the throttle there is a throttle position that i would say is before 1/2 half throttle that sputters. It almost sound like I'm hitting a rev limiter. I read the post on rev limiters and removed the parking brake limiter. I also checked, but DID not remove/ground the reverse sensor b/c the reverse light didn't come on when the sputtering started.
2. When the bike starts to sputter on level ground, I can usually give it more throttle and it will sputter for a second and then run fine. If I'm climbing a hill, giving it throttle doesn't work. It just keeps sputtering and dies, or I down shift to first, or I pull the clutch in, give it throttle, to get it past that point.
3. I checked the spark plug and it looks like I'm running slightly rich.
4. Other than that the bike runs great. Any help anyone could give me would be greatly appreciated. Also, if this is in the wrong section please move the thread. Thank you.
