Clutch Knock

[Html33]

Hi Guys n' Girls

Just stripped and rebuilt the headstock bearing, still had the original OEM one fitted and had an awful notch at 12oclock. Lovely bikes to work on, was easy to lift old one out, new one in! Was a pleasure to work on.

Any way, i went out for a spin earlier and noticed when the clutch was out and in netural, i could hear a knock, i could also feel it through the seat and frame etc. When the clutch is pulled in that goes away just leaving my slightly noisy cam (getting a manual cct soon)

Any one got any idea of what it might be? Bike is new to me (done about 200miles, bike has 31k) but seems to pull hard, strong clutch, starts on the button and revs crisp.

thanks

What rpm do you have the bike set at on tickover?

I bet it's that! it sits at literally under 1k, but higher than 900rpm, id say probably 980/990 RPM. Although responds nicely. I'll adjust that up to book spec 1150-1250 and get back to you!

Try between 1200 to 1400, but only when the bike is fully warmed up.
You'll know what sounds right, these engines are good for revving so 1250 is normally a good spot, under 1000 is simply not enough.

I've had a few bikes mainly Yamahas that knock ? seems only when no load if it works ok nothing to worry about try a Ducati dry clutch if you think yours is loud ?

Wow, my top headstock beating took loads of swearing and various shaped metal bars to get out.

I didn't bother taking the front fairing or tank off when I did mine.
