CB750 / cam shaft oil starvation
« on: January 16, 2012, 04:31:11 PM »
Hi

Well started my bike for the first time after about 2 months, Ive stripped the engine replaced all seals and gaskets etc, replaced inlet valves also after finding they were bent !!
I've looked on this forum and was paranoid about all sorts of stuff so after about 5 minutes of the engine running I removed the tappet adjust covers and looked inside,seems 1+2 cylinder has oil around the base of the valve springs,took 3+4 off and they are totally dry. May be me but I thought that because that the bike was on its side stand the oil might have gone to one side ???
But to be honest think that I may be fooling myself !!!!
I remember when fitting the cam carrier there was two oil ways coming from the centre head bolt which had o rings around them and another two oil ways in the head that didn't have holes in them but strangely still had O rings is that normal ?
Think I will have to take the engine out again (third time !!!!!!!!!!!!) and have a look at the oil ways to the cam shaft, anyone have any ideas/photos about what I should be looking for.

Although its dry on one side I do feel lucky that I haven't ridden it and snapped the camshaft and made even more work/cost for me..

would really love to hear your comments, I've got tomorrow off so will be stripping it again then if needed !!

Thanks

CB750 / Honda cb750 K5 with F2 front end front end soft

Hi
 can any one  give me some advice I have a 1975 K with a F2 front end, the front falks are quite soft I seem to be able to push them down quite easily I have changed the falk seals and replenished the oil,I was told that Medium oil should be used to refill them with 10 viscosity 155CC s of it .. the manual stated 10/30 Castrol TQF which from memory is car PAS fluid and auto gearbox oil ..

any advice greatly received

I haven't ridden it on the road yet so it might just be like that normally but Im sure my previous bikes were not as soft..


Thanks again

Amos  ;D
