weird screeching noise when driving with engine cold?!
Hi everyone,
Winter is here so i´m preparing to do some maintenance on the bike and need some assistance.
I noticed this spring/summer a weird screeching/hissing noise coming from the engine/front of the bike. Best I can describe it is I start the bike everything sounds normal, get on and give it some gas while its still cold and when I lay off the gas at maybe 40 mph the noise is very noticeable. I brake and get down to maybe 20 mph and the noise suddenly stops.
This noise only comes when the engine is cold after I rev it up at speeds before stated.
Has anyone dealt with the same thing and found what the issue was? it does not sound good. Was not able to take a video since its only noticeable at speed.
I feel sometimes the engine does take a while to heat up to operating temp but then again I live in Iceland! Could it be something with the thermostat or is it totally unrelated.
Thanks,
Eidur

The noise only appears when the bike is at speed off the stand, I revd the bike many times on the side stand but the noise never comes.
Not sure what it could be in the drivetrain since it´s only coming when the engine is cold.
I went through all the electrics, forks, brakes, fuel system last winter, bike runs great other than the carbs need syncing.
I know the noise description is very vague, was hoping someone recognized this.
Would maybe something with the oil pump or stator make loud screeching noises like this when failing?
