did you change the drive belt?as this can cause the screeching noise you are talking about if the belt is baggy and worn its similar to the noise a fan belt on a car makes when its loose.

ok no probs,you can buy the clutch shoes seperately try ve.uk online they sell everything you will ever need for it.the nitro will be either a blocked main jet or a faulty fuel tap (possibly not piped up right or split in the vaccum pipe)or could even be water in the fuel,the water sinks to the bottom so it would need to be drained(the tank that is)and also the float bowl on the bottom of the carb ,it has a small screw on the side at the bottom just unscrew it 2 turns not all the way out and see what comes out of the pipe at the bottom it should be only petrol and no water at all put something clean under the bike ie a plastic sheet when you do it to see if its water or petrol if its mixed then the water will LOOK like jelly in the petrol,but whatever it is the problem is the fuel not getting into the carburettor main jet properly ok glad to have helped as always mate.:)
