[QUOTE="luvtoride, post: 823619, member: 250"] Fred, I do believe that was what was speculated about my bike (fuel washing walls of combustion chambers causing loss of compression). First time it happened, I didn't get her fired up right away. I brought bike to dealer a few days later, who said my starter was going bad. They told me that another known battery was tried in case mine sucked & did not make any difference on the "really slowwww engine turn". I say "funny, it was just spinning it's ass off the other day". I went & gathered her up sweating what the problem was since they didn't figure it out. Further investigtion was done by S76 (Bob), who checked my valve clearances since I thought I may of bent valves by the way it just turned normally for a revolution & then spun. He said valves didn't appear bent. He squirted a bit of, I think it was silicone into each cylinder, put the plugs back in & did WFO throttle & bike sputtered & started blowing black smoke all over my friend, Jay who was sitting down in back of the bike. Speculation was that flooding caused oil to be rinsed off of chamber walls... hence loss of compression. Once the gas dissipated, there was no lubrication for the pistons... hence the slowwww turning bike experienced by dealer. I'm no mechanic by a hugely long stretch... but think this is what I was told. The second time it happened I was aware of the issue & I was more adamant about getting her started. [/QUOTE]
