"drowning" the engine and smoke from the exhaust ?
The other day when I was out driving my aprilia rs 125 -02, I was driving in about 50 km/h and then it started sounding like I was drowning the engine when I wanted to accelerate. It also starts to come grey/white smoke from the exhaust. I let go of the gas for a second and then it was no problem. 5 minutes later the same thing happened, but now the "drowning-effect" and the smoke doesnt disappear. It's no problems when starting it, but when I put it in a gear and try to drive it just dies. I noticed that a wire that are above the beginning of the exhaust was broken, but I don't know if it was broken before. Any ideas on what the problem and/or what the wire is for ? Help would be appreciated
