wverrring noise in my xr100

Recommended Posts

i have a new to me 1999 xr 100 pretty low hours by the looks of it. it e\runs good but it makes a slight "wverrr" when you give it gas. it does it every time all the time the gas is on. i probably would not worry too much about it but my two other hundys dont make that noise. i know its a lousy description, sorry, i dont know another way to describe it. it does increase pitch with rpm but gets no louder. any guesses?

i know an old automotive trick was to get a piece of wood, hold 1 end to the motor, the other to your ear. it works like a cheap stethoscope. it will get louder as you near the problem area

since motorcycles have spur gears in the tranny, they can be a little loud. a car transmission has helical gears which are much quieter. i know my 100 makes a bit of a whining sound from the gears.
