My engine's developed what I would describe as a tick. It's consistent with engine revs and you can easily hear it, any thoughts?

Pretty sure it wasn't there before the bike was taken off the road for about 2 months.

cam chain ? does it do it when you pull the clutch in ? does it do it when its hot ?try and do the screwdriver against the ear to pinpoint were its coming from

it does do it when you pull the clutch in, and I think it's more noticeable when the bikes warm. Sounds like it's coming from the front of the engine to me.

has it been run low on oil ? hope not

no, as soon as the alternator cover started leaking it was taken off the road.

Why? what does it sound like to you?

Mine is ticking as ´ell now and i KNOW what it is as i didn´t get really big shims in time....so valve clearence is to large.....on mine anyway.

I'll see if I can get a sound clip, it doesn't sound particularly bad and the engine sounds and feels exactly the same other wise, it just ticks.

cant see it being the valve clearance they don't usually go bigger ,, are you sure its not the slides in the carbs ratting,, gaskets on the exhaust downpipes ??

Carbs wouldnt make a noise at the front of the engine though, what about the rad fan?

well i've been told it sounds exactly the same as it did before, i'll keep a close eye on the oil and see if it gets any more noticeable I guess
