I am another FNG here (picked up my 08 Uly a week ago) and have read a LOT of impressive info here I still have one lingering question. While this was going to be THE bike I wasn't going to screw with, it appears I lied to myself again.

The most common ( almost necessary ) mods seem to be the crank vent reroute and of course the exhaust. While I haven't gone so far as to investigate the complete routing of the vent system I am still left wondering why no one has added a nipple on the exhaust and routed the vent there.

Here is how my distorted logic plays out in my mind, please show me the error in my ways. ( I have been called a moron before lol)

1) The discharge vapor which is minimal anyway would be heated to the point of steam and ejected out the exhaust. We are already discharging approx a gallon of water vapor for every gallon of fuel we burn as a by product.

2) If at the same time we create a vacuum, through a venturi effect of the exhaust, that we can utilize to reduce the crankcase pressure we actually enhance our engine performance. If the vacuum is excessive I can install a relief valve inline. NASCAR and NHRA already use vacuum pumps for this purpose and basically use a dry sump system like we are looking at.


Just some early Sunday morning thoughts from an FNG. My ECMspy arrived yesterday, anyone with an 08 have the perfect map?? LOL It's all new to me.

Don't get too excited about ECMspy with an 08, it's not as simple as it seems.

Unless oily, just drain re-routed breathers to earth.

By 2008 Buell's EFI-ignition progress rendered ECM Spy software obsolete to ordinary folks.

I think that you would be plugging up your muffler with un-burned oiliness.
