Hi guys, ive got a 2003 R1 engine in my MK Indy and was just wondering what all you guys have done with the breather that comes off the top of the gearbox and the ones that come off the throttle bodies ?
Cheers

Mines the later R1 and needs more complicated breather arrangement, but as far as I know the '03 usually just has the gearbox breather into a catch tank. Most I've seen just have the TB breathers open to air. Other than that you just need a sump baffle.

I've got an 03 R1 and what Adi said is how mine is.
