[QUOTE="Welldunn, post: 838957, member: 14105"] The valve checks were done at 28k, 60k, 83k. All by the same dealer all came back no adjustment needed. I knew that was suspect and should have taken it someplace else but never got around to it. We are 90% sure the valve burned then broke because the clearance was too tight. The rest of the maintenance was done by myself. The only oil to run in the bike was yamalube and changed around every 3k - 4k. The head is very clean No oil varnish, very little carbon. My new mechanic was real impressed with how clean the head looked. If the valves had been adjusted properly I believe the motor would have had many more miles. At the time of failure my oil use was near zero. If I just had to replace the valves and lap the seat I was looking at a $1500 bill. The worn valve guides and all the work needed to replace them was the deal breaker. $2500 to $3000 was the estimate. I did find a new head assembly on line for $1300. [/QUOTE]
