So I permanantly blocked my oil filter bypass

[barryh]

You abandoned the idea then of having a permanent bypass by drilling a small hole through the plug. Problem would have been deciding what size hole to drill and it would have bypassed a lot more hot oil at running temperature than cold oil at start up.

My personal experience is that synthetic oil (of any viscosity) in airheads causes leaks.
I stick with regular 20w50 and change it often.
Maybe your results will differ.

Yeah, a permanent bypass hole would always pass unfiltered oil. That's going to take a toll at some point.
If a smaller hole was drilled to pass less unfiltered oil, then it possibly has a limited flow function if/when required.
This is why I was keen to recreate a seat for the spring, and mostly preserve the oe parts, and aperture sizes of the bypass inlet, flow past the ball, and the outlet to the main gallery behind the bypass.

Yea....but you only get what 400,000 klms to a bottom end!

I've been running mobil 1 15w50 for the last 25 years in my R100. I get a bit of seeping from the push rod seals, but that's all. I ran the same oil in my R60/2 for seven years without a leak.

"Mechanic from Hell" cannot have ANY leaks!!!!

yeah, I think a full blown leak's preferable to a weep.

My engine doesn't leak because it gets pulled apart so much.

I understand that at one time the Israeli accessory firm Motoren made an adapter for BMWs that allowed the use of a spin-on oil filter canister, like a car has. I suggest this becasue the spin-on type oil filter has the by-pass valve built into the filter itself.

Couldn't find the adaptor on the site. Doesn't the remote oil filter hang off the front of the engine? Might not fit inside an RS fairing.

Thanks, Kurt.
Interesting piece of kit. I'm curious re the mating and sealing of the diversion, to the engine case oil filter inlet/outlet galleries.
It would solve the problem, but create another with the bank account. Plus my fairing would interfere.

I also have an amount of unaccounted for broken spring. I couldn't find it at the rear main, with a magnet poked up the oil pressure switch gallery. It's a tear down to find it so I'm hoping it's a big enough single piece that will be caught up and not get into the front big end or front main. The oil light hasn't come on yet.
