I seem to get a loud knocking noise when I accelerate hard ? I thought it was the infamous chain hitting the frame because maybe the chain was loose but the chain is fine ? Im sure I read that this is a WR trait, but did I dream it because I dont want anything to be wrong . It doesnt happen all the time so should I be worried ? When I first got my bike (With around 2000 miles on the clock from new) I started changing gear without the clutch but only on the trail, untill one day it it wouldnt change up without the clutch & whilst going along it jumped out of 3rd or 4th gear , after that I use the clutch all the time. Do most people use the clutch all the time on there WR after pull away ? or it it something more sinister wrong with my bike.
