rotten throttle bodies

[Paul Minnaert]

I still have original ones after 12 years, no problem.

But someone else took a good look and he sugests that the angle of the bodies and the intake is not the same, so there is tension all the time. Try to dimount the fixed rod between the bodies and see where they want to go.

I had the same trouble with the rubber intake sleeves. I bought a new set & the same problem recurred within one riding season. At the same time however I was having trouble with my tb's not being in sync.

After I bought the Twinmax tb sync & learned how to keep my bike running smooth I havent had any trouble with the rubber sleeves at all.

The factory set was cracked & looking bad with less than 1000 miles on them so I know the oem stuff is poor quality. I'll have to wait until a few more thousand miles go by before I pass final judgement on the new sleeves & their quality.

I replaced mine last season when I noticed cracking. Simple job, do it yourself if just for the peace of mind it's worth the cost of the sleeves.
