Noise from Trans when in gear
Guys I have a 'scraping' noise coming from my clutch/transmission area when the bike is in gear - not constant and sounds like it's happening once per revolution of whatever's causing it with the frequency increasing with engine speed. Completely disappears when the clutch lever is pulled in or in neutral s presume its part of the trans?. Sounds kinda like a warped disc would if that makes sense. Any ideas?

If it were a warped disk making the sound, you would hear it when the clutch is disengaged.
Since you only hear the sound when the clutch is engaged, you can also eliminate the clutch hub bearing.
People can guess what the issue is all day long, but this will get you nowhere.
Since you know where the sound is coming from, I suggest you start by removing the outer primary cover and inspect everything.

If noise goes away when pulling in clutch, consider inner primary bearing. Not saying that is your problem, but the noise going away when pulling in the clutch is sign of a failing IPB.
How many miles? Any metal in the primary fluid (expect some very small mounts from comp, chain, etc). Any leaks?
