Please help me out.

I can not find the reason behind the Grinding Noise on my FIDDY. It shifts fine when the bike is off, But when the motor is running and I move that SHIFT LEVER up or down then you hear a grind noise. Like the clutch isn't disengaging. ?? I took everything off 4 times and didnt see any wear ot tear, No grinding marks nothing? What can this be?? Does anyone have any idea what this could be?? :oops: :x :(



Thanks

to adjust the clutch do not do what the xr50 service manuel tells you to do cause it is exactly opposite. what you need to do is loosen the nut (14mm) on the right side cover, there is a flat head screw in the middle of it, turn the screw all the way counter clock wise until it stops, after that start turning the screw back clock wise until you feel resistance then turn back 1/2 turn and tighten the nut (14mm) back. that is the correct way to adjust the clutch. But the grinding noise may not be fixed if you adjust your clutch right. The grinding noise is the back side of your clutch basket hitting the screws on your larger oil pump. If you look at one of the screws and the back side of your clutch basket you can see where it is hitting. You can take a grinder or something and flaten out the screw.

Yeah some people say 1/8 turn and some say 1/4 turn and some say 1/2. Any of the amounts will work. The more you turn the screw back after resistance, the more slack you will have in your shifter. I think 1/8 of a turn is not enough. I would rather go 1/4 turn than 1/8 turn but thats up to you. Yeah you cant really see any wear on the screws but if you look at the back of the clutch basket you will see where it hits.

The Clymer manual said to do it backwards. I just fixed it THANKS PM!
