Hi everybody I've recently fitted a full dep pipe on my DTRE 125 2006 model run up to snake pass at weekend to test with a new spark plug in to see condition of plug bike ran ok but I noticed quite a lot of oil coming from tail pipe and splashing my rear fender and number plate .? I haven't re jetted carburetor yet as I was told to run nine first to see condition of plug . Plug looks fine and bike ran reasonably well does anybody know what the oil could be and is this because it's haven't re jetted carburetor.? Any advice would be appreciated . Thanks Karl
