So my saga continues,

After an engine failure at Browriggs a few weeks back, I finally had time to strip the old bugger down.

Prior to me getting the bike, it had had new main bearings and seals. Happy days. It's never ran right though.

Had a lot of good advice from you cracking folk on the forum, lots of things to look at. People kept saying "crankcase oil seals? Water in the oil? Leaky gasket? I said, well there all new, I can't be that, but bloody hell, it was!

Split the cases tonight and there's milky goo in the crankcase. Gasket was brand new but had failed.

Water pump seals had gone too along with kickstart shaft seal.

I've never been this far into an engine before, but the workshop manual is brilliant.

At least I know what's going on now. Good job I enjoy being in the shed.

Any hints or tips on the rebuild would be very gratefully appreciated.

Lightly grease your gaskets.

 

Apart from help keeping them in place when building up, it can stop them sticking and ripping if you have to remove/undo the parts again.

Thanks Goudrons,

I was going to use a non hardening Loctite gasket sealant, but will grease do the job? If so, then happy days.

I'm not a fan of all those instant gasket gunks unless required because there isn't a paper gasket. (like some Yams centre cases)

 

If the mating surfaces are clean and in good condition, a greased paper gasket will be fine.

I've got a full gasket set to go on so I'll try it with a light smear of grease. Thanks for the advice.
