The engine oil breather now just routes directly to the chain oiler, the oil tank still routes to the air filter, all seems to be working well.

The chain oiler is a port off of the return oil line banjo on the central oil tank (above the feed banjo). I guess that would work. It wouldn't be splashing up into the oil tank breather. I may try that. I reckon you're talking about that little line off the return banjo Josh?

Why did you re-route the breather?

Why not try some straight 50W in it. That's what I've always used.

The photos don't do justice, having seen the beast in real time ~ (but I guess we are talking mechanics here lol )

I had issues with oil leeching back through the breather into the air box but after dropping my 'correct' oil level to half way up beteen the original ful and low mark on the dip stick the bike has been fine in that regard !

Also experienced the balance tube coming off ~ only once though. Curious event ?

Thanks Stu.

Dave ( the Dave that likes traditional, non gay coloured motorcyles , I'm suprised Jordan isn't painting his pink...... ), there was oil / oil vapour dripping from the KN99 air filter.

The little return line blocked.

The air filter breather from the tank routed to the air filter.

The crank breather, from the external PCV, to a 3/8 to 3/16 reducer, out onto the chain via a chain oiler ( Norvil sells them ). 200 miles, no mess other than the usual splash onto the rear wheel from the chain.

So you're dumping the residual oil from the breather (not the timed one, your new breather off the timing side) on the chain oiler feed? Hmm. I never liked that chain oiler and whacked it off first opportunity. I'm using the old timed breather off the left side crank to the top of the oil tank, and the oil tank breather has a hose like yours, but it goes into a catch bottle down between the crank and the gearbox. So far no oil dripping except I do have a slight weep off the very bottom most engine mounting stud.

I always found there was way too much oil going on the chain, that's why I cut it off back in the 70's. But then I had plenty of oil all over the bottom of the engine, gearbox, swing arm from things dripping. It was like an oil nightmare. So far with new flange gasket material (Hylomar) and better sealing, I have a very oil tight 69/70 S model using my standard timed breather and the catch bottle.



Not that I'd not go for the new comnoz breather if I can afford it.

Dave, when you said 50W, did you mean SAE50 ?.

Yes, VR-1 Valvoline SAE50 Racing Oil. It has some zinc in it, so is probably not street legal. It seems to work fine for me. I think it also comes in multi-grade.
