cpi pipes leaking

[01 250exman]

Is there anything I can do to stop this?
I was thanking about using RTV,but I dont know if it would hold up to the heat.
Someone els have this problem?

My fmf's do the same thing and I even have new orings in the pipe. All 2 strokes do it, Pretty much gotta live with it.

High temp RTV will hold up for a little while. It would last about 2 months or so on mine, then just pull it off and reseal it again. Not the best fix, but it works.
Use the high temp BLACK RTV, it seemed to last the longest..

That sucks because the stock pipes dident leak at all. Although I diden't replace any o-rings and Iam not shure if the cpi's came with some,are they inside the pipe flange that buts up to the head?

Yes. If you look inside there should be a groove cut into the flange. New pipes don't normally come with o-rings. You can reuse the originals, or just order new ones from Yamaha. They are around $6 each.
