Engine Noise
Hello all,
Does anybody have what I think to be engine noise once you run the RPM's up to 6-7K? If you look at the front of the engine just behind the fender, the clutch cable will sort of make the same sound if you tap it against the frame. Now this sound goes away when you ease up on the gas and picks back up when you get on it.
Now this could be the clutch cable vibrating at speed, but wanted to see if anybody else has this issue and has resolved it.
I have 4700 +- on my completely stock 250s
The book says valve check at 7500 and that's when I plan on having it done.

RE: Engine Noise
What does the noise sound like? I have heard a jingling noise sort of like keys bouncing around on the triple clamps...
But it's not that. I still hear the noise to this day, even after 331 upgrade and valve adjustment.

RE: Engine Noise
Funny thing about the valves, I have had them checked 3 times and every time the shop says they are perfect. So what gives? How come some guys are getting them shimmed? Oh and one of the noises I have figured out was the gas cap buzzing, I took it all apart and its the tiny springs making noise, I tried to stretch them but it still makes that sound. But you can bet I will be checking out the clutch cable, I remember I wrapped it with black tape where it goes through that guide in the front of the engine, but maybe my tape has worn off, thanks for the reminder.[sm=smiley20.gif]
