How would it work with the early timed breather off the left side and the original drillings in the timing side, which I understand are different than the later ones when they did away with that timed breather? I suppose it would be best to block the timed breather port. Or would some new drillings be necessary in the timing side to the crank?

The early cases don't have the large holes into the timing chest so you don't have anything to plug unless you want to plug the small oil drain hole and relocate it down lower.

All you would need to do is cap the original breather and connect the hose to the new breather. Jim
 
Thanks Jim, looks like a great answer to a never ending issue. Let us know when it's going to be available generally, I'd be very interested.

Cool idea, how far beyond does it stick out compared to the stock plug?

It sticks down approximately 1 inch farther than the original. Still not the lowest part. Jim

It will need skid plate protection on my special, it will be flush with the bottom of the frame rails.

Looks like an excellent solution and hope to be able to afford one when they go into production. I`m sure that this will be considered the next must have as no cases will need to be harmed and the mounting looks super clean. Where's the "taking my hat off to you sir" smilie?

So, this item will do the job of both the PCV and present sump plug ?.

What happens if the engine wet sumps ?.

Good question Josh!

The breather pickup is the same height and very close to the pickup on my older breather. If the engine is started with a sump full of oil then the oil passes through the reeds and back up to the oil tank. It will help clear the cases faster than the scavenge pump alone.

Let's see how many people think a dry sump is actually wet. :mrgreen:
 
Are you trying to start another wet sump thread SD? I think we've had enough.

It certainly looks like an elegant solution.

(fantastic workmanship and great idea)
 
Sleep- what's that?

I do read ADV rider once in a while.

Thanks Jean and all.

that is a great looking product and I am sure that there will be substantial demand for it - of course subject to the perennial issue of price.

I want to pick up on DogT's question to you and your response. You have said that those of us with the left hand mounted timed breather (early bike - 1970 and earlier) should block that off; and mount the hose to the new breather; do you mean that your breather is to be mounted to the crankcase in a different position than the existing breather hose on the early model bikes? Where is that - is there an existing tapped hole in the crankcase, or does one need to be drilled and tapped on our bikes? Or could the new reed valve be screwed straight into the existing L shaped exit pipe, or the crankcase where the L shaped exit pipe connects to the crankcase now?

It replaces the sump plug and the L shaped exit is blocked. The second from bottom picture shows where it goes

DogT,
What is the "never ending issue", my M3 after a 40 mile run is BONE dry...not one spot...and its stock as the day it left the factory..46 years ago......the main differance it's UN TOUCHED BY IDIOTS,

Chris,
This assembly replaces the large sump plug in the bottom of the crankcase on any motor except the 72 Combat engine which lacks that plug. The breather hose that originally went from the engine to the oil tank- left front of early motors or right rear of later motors- now will go from the new breather to the oil tank and the original breather is capped off.

On the 72 engine which lacks the crankcase sump plug my earlier model reed breather can be bolted to the rear of the case in place of the original 2 bolt fitting. Jim

John, I can find you plenty of people with 69/70 bikes that were never dry right off the show room floor, including mine. Not that oil is running out, but it comes out of the breather in the front of the oil tank in the air filter, drips down through the filter to the top of the gearbox and then on down to the bottom where the air takes it all over the rest of the back of the bike. It's enough to collect the dirt and oil in thick amounts behind the gearbox and swing arm after a time. I have fixed mine by using new flange/gasket materials to keep the oil in the engine (yes, it leaked too), and I installed a pipe off the oil tank breather to catch what does come out. Now it's dry except for a very tiny weep off the bottom most engine mount.

I don't know why some do and some don't leak, but with better crank vacuum I'm sure it would be better for a lot of people.

Jean,
The way I understand it, we would block the timed breather on the engine and just put that breather hose on his valve off the sump.

Quotes are getting confusing, I reckon that answer was really meant for Chris T, the antipodian.

Another outstanding idea, you're making it easy for the rest of us Jim. Count me in, I want one too! Cj
 
Does the new type breather reduce the oil level in the bottom of the cases, and if so is there any need to pressure feed jets to lubricate pistons/cylinders?
