Noisy clutch while its engaged
 

Hi I have a 07 ec250, over the winter I did a complete rebuild of the engine, every bearing and seal was replaced, crank was rebuilt and the top end was replaced. I just recently got around to breaking the engine in, at first it ran great then it began loading up, long story short, I knicked the right side crank seal and it was burning oil. While I had the clutch back apart, i replaced the clutch basket with a Barnett basket that i had from a parts bike. Now that its running again I have a growling/bearing sound that goes away when I pull the clutch in. I used my new bearings with the basket, everything looked good on the Barnett basket. Just looking for some help on what to look for when I pull it back apart. Thanks

What you described sounds like "roll over" noise.
That's the transmission gears meshing together.

I would try a differed transmission fluid.

I've been running type f atf, I'll try a different fluid tomorrow and see if it helps.

I changed the oil with amsoil 10 40, and it did not change the noise at all. Any other ideas of what it could be?

Hello, the mistake of the clutch turned up?
