Hello i just bought my first raptor, its an 05 660r se and it was well used. I have done some research and i believe it needs a timing chain as i can here rattling in the top end, and starts and idles easily. Im going to pull the auto cam adjuster and check valves this weekend. I havnt had a chance to go over it real good yet but i noticed it seems to clunk pretty good going from neutral to first, and worse from neutral to 2nd? it does jerk forward a hair as well. I have a drz 400 and that doesnt do it like the raptor does. It goes into reverse and the rest of the gears with no clunking and can find neutral easy. Also the rear brake isnt working, the piece for the e-brake is only on by one bolt and is loose could that be why? the brake pedal can be push all the way down easily. and is plenty brake pads left. im hoping they just need to be bled. Like i said im going to go over it good this weekend but just looking for a little direction.
