Ok. Before you read this give me the best news first folowed by the bad last. My bike (that i bought as a project - GPX250 98') had petrol in the oil. When i say had petrol in it. When i drained the oil i filled it into 2 litre cordial bottle and it filled up 2 and abit which is over the 1.9 it should have. I ran it for about 2mins until i discovered this. Also the bike wouldnt idle. When i say idle it wouldn't idle at a normal speed. It would hover aorund 3000rpm then after about 5 secs would slowly die and wouldnt be able to keep it running unless i kept giving it little blats of the throttle. Would this have something to do with the oil contamination or is that another can of worms (carb). Now this cant be good can it? But what are the possible causes of this (the petrol in the oil)? Cheers.
