I have had a problem w/ my front end on my 05 636 since about 600 miles. I've noticed a chatter in the front end. I took it to the dealer and left it for 2 weeks they pulled the front end and put it back together said well they don't see anything and that they torqued the steering head down tighter than factory specs per kawisaki. this caused the bike to steer very funny ( turning left it wants to flop into the turn and on a right turn it doesn't want to turn). The chatter is still there. I relate the sound to a music instrument in a junior high band the hollow wood block that you hit with a stick just a hollow rattle. I've had some people say that it maybe steering head bearings etc. You can sit on the bike pull up the handle bars and hear & feel it pop. I'm tired of having people guess. It now also has a weird feel in the pegs when u say pull in the clutch and are rolling to a stop ( its very distinct from say 30 or 40) kinda of like click and then rolls for a second then click but u can feel it in the pegs I know it has something to do with the chain. But I was told "Oh thats probably just chain noise" well my opinion is it did not do it when I bought it so why not look @ it and fix the problem. if its not covered tell me so I can buy a new one. I've asked more than 5 occasions for help setting the suspension up and each time there is a reason they can't. my bike has handled like crap since I took it in for the 600 mile service. i weigh 230lbs.. I took it in for the last service and I noticed my coolant level was just below the low line and I informed them of this and when I picked the bike back up I fortunatley left my switch turned to on and my battery died that evening and when I jumped it off I noticed nothing had been added. ANY SUGGESTIONS on the issues I have stated above would help tremendously. I purchased it in February 05 it now has 8000 mi on it and has a two yr extended warranty. I do not walk it or do stoppies.
