You already said it all....if you don't like it don't do it.

Depending on miles driven, health of your engine (amount of blow-by), engine tune, and riding style.... the affects from CCV being ingested back into the engine will eventually foul MAF/MAP sensors, coat intake with 'gunk", build carbon on pistons and/or valves.... that will eventually affect performance... Too many variables to definitively say when or at how many miles an engine could be affected...

Many people may not notice, and/or may not care... If so, then as mentioned, don't do it.....

I ran tubing straight down from the backing plate, under the tranny side cover, and zip-tied a very small K&N breather filter on the end. This way, I have constant venting and no restrictions, and almost no possibility of pure oil making it to the tire.




I am also a fan of using something rather than just an open tube. My concern is not just the tire, but also the brake disk and/or the belt and pulley depending on which side of the frame the end of the tube winds up on.

The oil vapors being drawn in the cylinders aren't entirely burned up and the carbon deposits on top of the pistons just keep accumulating over time and mileage. As the these deposits keep layering up the compression ration is gradual being raised and the if the deposits develop a hot spot, then pre-detonation would start happening. I was taught the only components that are supposed to go into a combustion chamber is fuel and air. You are right as rain, it's your decision.

I understand the concept, but chose to keep it to what the engineers who designed it. Second, I use Shell Nitro premium gas that has twice the cleaning detergents than most premium fuels. Third, Once a season I give my scoot a shot or two of Seafoam, my friend let me borrow his scope and combustion chamber shows no signs of carbon deposits.

I'm not mocking it, just have a different way of coping with it.

It’s a shame there is nothing available today that can measure white knuckles & big a$$ smiles.
