Happy New Year Everyone,
Christmas and a the worst chest infection I have ever had has slowed me down on my rebuild but I am back to it now.
Come across a problem with my front cover leaking oil. I bought a new OEM gasket and all o-rings and assembled everything dry. I had noted that the PO had used lots of RTV which I wanted to avoid as I know the tolerance/clearance for the correct operation of the gear change mechanism is quite tight.
It took me a little while to figure out why it was leaking, it turns out that there is a small step between the crankcase halves, enough for the seal not to be able to compress enough to work.
The crankcase halves have a couple of dowels for alignment but clearly something has gone wrong, the PO used HEX head bolts as opposed to original for bolting the halves together which may have contributed to the misalignment.
So it looks like I am going to have to revert to a sealer, any opinions?
I havent put oil in the bike yet, what leaked was just some residual oil still in the crankcase. My worry is that once the engine is running I will have a similar leak from the rear cover as the step will obviously be there also, again PO had used RTV. Will I be able to get the rear cover open enough to apply sealer or will it be another engine out job to fix
