When i go to kick start my 97yz125 and i give it gas(only when its hot) sometimes its like the kick starter kicks back. I guess its from the gas igniting or something or me not giving it a good enough kick. How bad is this for the kick start mechanism(sp?). I couldnt imagine it being good. Should i be worried? Another thing, i havent changed the tranny oil in like 5 rides. It didnt seem to do this before that. Could the old oil have anythiing to do w/ it?
