New noise....(coffee grinder?)
I switched out my coolant this weekend with DexCool, instead of the green stuff, the fluid looked pretty healthy, no white globs or rusty colored stuff.
Anyway after I made sure I had the correct amount of fluid in it I started her up and let her idle with the choke on while sitting on the center stand. I noticed something slightly out of the ordinary. The back wheel, which was off the ground due to the side stand was slowly turning, I thought hmm never noticed that before.
Well I wheeled her out of the garage after this and put the bike on the side stand then I heard this weird noise.
The noise sounded like an intermittent rotating not really grinding but rubbing metal on hard surface noise, not overly loud but there nonetheless. It didn't make the noise constantly only seemingly at an undetermined RPM after revving it a little. This really concerned me b/c I've never heard this noise before. Next I took it around the block never getting above 2nd gear and varied my speed by accelerating and decelerating sometimes quickly other times not but wasn't able to get the bike to make "the noise". Sooooo I got back in the driveway, bike still not showing up to operating temperature, and still very intermittently the noise would re-occur.
I'm thinking that it probably isn't the ACCT because that noise would be constantly occuring upon acceleration and de-celeration right?? And if it were the ACCT wouldn't it sound similar to a loose chain slapping the chain guard on a chain drive bike???
OR is this that "coffee grinder noise" I've been reading about??
