Cold Start Knock or Detonation
Hey guys, I've ridden about 3k miles on my 06 rc51. They bike has about 40k miles on it but still runs like a champ. It had it's first valve adjustment at 16k miles and I am going to check the clearances soon whenever I have a break from school.
I have had a persistant noise since I've had the bike. When I start the bike cold, there is usually a loud bang noise once or twice under the gas tank and the idle will drop suddenly when it happens. Sometimes the bike just dies from it and I will have to restart it and the noise has gone away.
This only happens when I do a cold start while I am letting the bike warm up and putting my gear on. I use 93 octane ethanol free gas.. Any help?
The bike has two brothers slip-ons, it had a power commander but the mid-button is broken so it is removed. I only mention this because it occured to me that maybe the bike is running too rich?
