I never used much oil before the mod even though there was BB oil always present in the TB from the EPA imposed breather venting. I think running oil 1/2 qt low just to minimize BB is just crazy talk and personally feel I want as much oil available for lubrication as possible. I run my oil as close to the full mark as possible. I've never put a filter on the end of the tubing in 98 or present. Oil appears to blow out with none being inhaled back into the engine.
This is the normal amount of drip from my atmosphere re-route tubing.



This is the location of my route tubing:


No oil appears to blow back to the rear bike components.

 

 

Actually what you wrote is an opinion that goes directly against everything I have seen and experienced...

 

Makdaddy can that run in the horizontal position like that and still work right looks like the drain is in the center, do you have to remove to drain it? they said there is a baffle to separate air and oil. I like the idea of a catch can also, like I have had on my other motors.

 

Looks good I need to do this badly. I`m afraid what the inside of my motor looks like at 30k

 

After thinking about the catch can, is there any of you real smart people that can tell me if the stock breathers tubes that run down and into the A/C and fill with oil, if it were turned up above to the tank from the 9 to 3 o clock position, wouldn't the liquids run back into the heads and the oil system and just burn off the moisture, then just vent or positive air pressure would cause no oil splatter with a breather filter that would stay dry above the vent ports?

 

Shakrr,
You may be on to something. As long as the tube diameter is sized large enough to prevent clogging up, and the filter mounted vertically to prevent oil dripping off onto the engine, it should work better as you described. Great thinking!

 

I don't think so...as there are small rubber valves (if I remember correctly) inside of the head that close when there is suction from the pistons moving up..

 

It should It is designed to mounted vertically, but I rotated the filter to be at the top when mounted horizontally
It shouldn't leak. If it does that means the cylinder filled, and I have way tooo much blowby

And yes I will need to remove it to drain it.

 

=====================

Wouldnt bet on it but if you run a few tanks of fuel with a healthy dose (1.5oz per gal) of chevrons " Techron " (their " Concentrated " version) that's a fuel injector top end cleaner (cleans combustion chambers inc valves & pistons) on a reg basis starting with a clean engine things should stay pretty clean.

Run that hvy dose right before an oil change because hvy dose could poss foul oil with some contam from cleaning the excessive carbon out of comb chambers.

Then after doing the hvy clean dose of 1.5oz per qt of concentrated techron i'd run it 1x every 3k miles to keep the injectors/valves/tops of pistons & cumbustion chambers in general clean of carbon & crap from the combustion process.

Been doing that on my EFI & carb'd vehicles for yrs with great results,the stuff is fantastic and fixed partial clogged injector issues in cars i was working on where seafoam couldn't fix it.

And the " concentrated techron" cleans the intake valves on both sides like on the comb chamber side of the valves and also cleans where you would see buildup with the intake off the motor looking thru intake port on head where carbon/crap builds up on the backside of the intake valve too.

BTW,all the carbon buildup isnt just from the crankcase breather,its collectively together a buildup of oil blowby gases from the crankcase along with the crap todays pump fuel leaves behind too which chevrons' techron in the " Concentrated version" does a good job of cleaning.
