DT125R FORUM

Sorry Calum, but if you do a search on Google for leaky 2 stroke exhausts, you will find that a leaky exhaust will seriously damage a 2 stroke engine.
I'm not going to risk it. Yamaha exhausts are welded for a reason.

Hi Calum,
Might be ok for a bike going round a track a few times. But for a bike that's used everyday could be detrimental. I've read that it is crucial that the system is sealed as it greatly affects Carburaton, not to mention all the burnt oil etc. That will spread all over the engine. I think I will be returning the pipe and paying over the odds for a genuine pipe. Not risking damaging a perfectly good engine for a cheap bit of tat. I was told it was a direct replacement which it clearly is not.

Hi Calum, thanks for the info.
I'm not too worried about the mid connection, I can use silicon rubber pipe for that. It's the manifold end I'm more concerned about. A chrome plated manifold came with the exhaust which obviously screws onto the exhaust outlet, no problem sealing that with a standard gasket. But the exhaust simply slides over that and is held with a couple of springs. Not a good seal at all.

Hi,
New to the forum, I'm just referbing my 1992 dt125r and I have to replace the exhaust system. I've bought the above system and beginning to wish I hadn't. Has anyone fitted one of these and if so how did you seal the manifold and centre joints.
Thanks
Richard
