i took apart my crankcase breather, cleaned it up and reinstalled it, noticed taht the bike was riding MUCH better. Turns out the breather was loose, but you had to use a wrench to get it to move from all the grime. The crankcase breather allows air to vent out but never in. How does this affect how the engine runs?
According to you it runs much better if it's a working and air tight valve [cheeky]
My engine builder/tuner, who I trust, says the whole stock set up has to stay.
He has his reasons - I don't know what they are - I just follow orders...
Obviously it has to do with crank case pressure/vacuum, but others will have to explain how (again).
of heard of the benefits of having one as it helps the motor not create pressure inthe crank case. I saw TPO sell a kit that allows you to relocate the filter to another spot, but on the same boat (and ive said this many times) i was just goign to buy some piping and run it straight into the airbox.
i cant install the stock box beause my shock is in the way.
Yeah, I know you have no box.
Maybe an airtight sealed operating valve is the critical part.
Clean or replace [thumbsup]
If you can get to a boating store close to you, get enough hose to run from the breather to the rear of the bike and get a check valve like this:

Presto.
Had the same issue with my TPO crank case breather part...it was very loose and bike slowly died. Tightened it back up and it runs fine.
