Engine breather pipe

Post by LimitedEdition »

Hey guys, I'm in need of a little product knowledge. The thick black pipe on my engine is split at the bottom, my neighbour says its just a breather pipe and I am wondering if anyone knows a good cheap place to get one?

I'm also looking for a replacement screen as mines cracked, and I'm looking for some tarty bits anything I can treat myself too.

Hope everyones ready for the new season, alot of you probably never stopped riding but I'm itching to get back on the big bike.

Cheers, Alex

Are you still running the stock oil catch tank? The breather line ideally should have a one way valve in the line to keep a negative pressure in the crankcase. Reduces oil leaks and increases power.
Here's an article on crankcase breathers. Big science, or just blowing hot air, or both?

The screen can be had from Zero Gravity

At least its still listed on their site.
