Hi
I have a Staintune exhaust for sale if anyone is interested. The pipe came with the bike but I prefer the standard so refitted it. It has done very few miles and the condition is nearly new.
I'll upload some photos asap.
Thanks
It is louder than the standard and to be honest I didn't think it was appropriate for green laning.
However, for road use it's fine and it actually sounds really good. So for a Supermoto look it would be a good exhaust.
With regard to the jetting, it ran fine on the standard carb set up, but you can download instructions from the Staintune website. Depending on the age of the bike you may have to change the pilot jet, but they do say you should change the slide position.
