Which downpipes

[mr self destruct]

Ahh cheers, that clears it up somewhat, I think I'll be ordering some of those

Par6, how did you get on? I ordered some Venoms on the strength of this thread and put mine on yesterday. I found a few differences between new and old though, which this reply on the other thread would bear out:

(I also asked him about the restrictor point near outet). "The outlet on the downpipes is the same size as the Yamaha pipes because it is designed to work with the OE gasket in place,again though,a lot of the Chinese parts are designed with larger tubing to do away with the use of gaskets. The pipes are made out of the same material by the same people here in the factory..like i said,these were introduced for one reason only..to compete against the Chinese and keep the Motad brand separate.You can order direct on 01922714700,the price will be £139.99+ £12.86 postage."

I don't know what the old brand of stainless pipes were, but the steel was a lot thinner than the Motads (to the point where I thought I'd bought the wrong pipes!), and there were no gaskets on the head.
What I found was that the pipes were leaking through a corroded weld (which is why I looked at replacing them in the first place) and they couldn't have been a good fit to the head. I say this because when I took them off, the clamp plates were all bent to shit, and the head studs were bent as well. Probably by a guy who overtightened the nuts to stop any leaks, so obviously the clamps were too thin as well.

The Motad Venom pipes were easy to fit, bolted straight up, no messing about tweaking them to fit so I'm happy with them.
