Oil leak

(1/3) > >>

Andy1976:
I've managed to get my bike running and after I took it for a short run I've found oil leaking from the cylinder head.
What causes oil to leak and how do you fix it?  ???
Other than this everything seems to be fine.

Thanks
Andy.

Hi Andy are you sure its the head ? if it is then you will need a new gasket, it could also be the rev counter drive oil seal or one of the tappet covers leaking , cheers Mick.

Andy1976:
Hi Mick,
I'll have another look tonight, Ive gotta go to work now. :(
Thanks
Andy

Andy1976:
I've had another look this aft and it seems to be coming from exhaust tappet covers on 1&4 so that can be easily fixed.
But..... on start up I get quite a bit of white smoke, which seems to thin out as the bike warms up. Is this a dodgy valve oil seal or is it still burning off excess oil from the rebuild?
I used quite a bit when putting it back together and I only did 2 miles when out doing a test run on sunday.

Thanks again
Andy

Hi Andy that sounds like an easy fix if its only the tappet covers  ;), mine smoked for a while after rebuild and i used plenty of oil whilst rebuilding seems to have settled down now  :), cheers Mick.
