400ex rattling noise
#12
Most likely you are just hearing the valves 90% of 400ex's have this problem with "Ticking" noise. Its very common. You could check your valves and ajdust them if nessicary but even when in specs you will still hear the ticking its just hit or miss with them. If you visit www.exriders.com you will see about 100 threads about this.
