Exhaust Flushing
Im just wondering what the best method for flushing the exhaust is? As I constently have oil dripping from where the silencer connects to the main exhaust, is this normal?
The exhaust is a FMF Gnarly from front to back.
Also is it just the first section of exhaust that needs to be flushed, or both it and the silencer?
Cheers

Re: Exhaust Flushing
Don't really need to flush either. Replacing the glassfibre packing in the silencer will cure the problem for a while. The reason you haver the gunk is that the engine does not burn much of the 2 troke oil that goes through it, particularly if you are using synthetic or semisynthetic. Also it can be a sign of the engine running rich - which is not neccessarily a bad thing. It just depends on how quickly the gunk builds up. Also if you go on lots of short runs/low speed and don't get the exhaust up to temperature.
