Need help with Jha pipes leaking

Wed May 10, 2006 2:58 am » Post: #1 » Download Post

I have a set of Jha pipes that leak from the part where the pipe connects to the flange. Does anyone else here have that problem and a solution?

Seriously though, there's a crinkly seal in the Jha flange that gets crushed in no time and causes the leak. The best way to to use a good smear of Hi-temp RTV on the manifold before you put the pipe on, then give it half an hour or so to cure before starting.

The nuts only tighten the actual manifold down onto the gasket. That's the first part sealed just like the stock pipes. The sliding fit of the pipe onto the manifold also needs sealing, and this is where the sealer comes in. I use Permatex Hi-Temp. Comes in a red tube and smells pretty sharp. Make sure you degrease the manifolds and pipes before using the sealer or it won't seal properly.

Cool, will do!! Is there a chance that damage could be done if not sealed properly? Ive already done a track day and it seemed to go fine, but i got another day comming up on the 24th, so need to know if its worth doing before hand, if there is no thret of damage ill wait as i gotta take it all off to fit the new suspension anyway, Cheers

No it'll be fine RC. They all splurge out the burnt oil if not sealed but you wont affect the mixture or breathing from it doin it. It's just messy!

do the Jha pipes use 2 orings in the flange?
the ones I have have 2 groves which look like they are for a pair of orings on the flange. the pipes then slide over them.

Remember that a two stroke engine vibrates a lot, and if the exhausts were solid mounted, they'd need to be very strong to withstand the vibration, hence the reason the lightweight pipes are best fastened on with springs.
