I think the balancer finally went on my starboard 2005 yamaha 4 stroke. Motor has 975 hours and was throwing the timing belt. Took it apart to find out the motor had a small wobble in the cam shaft. Opened the valve cover and sure enough the tops of the cams were fried. The cylinders look good just a little tiny tiny abrasion but nothing cracked or noticeable damage.Did a compression check and all 4 cylinders were great. I am going to order a new head assembly but I have a couple of questions.
1. With a new cylinder assembly, will the motor preform the same even with a very slight abrasion in the cylinders? (by the way did a compression check and all 4 cylinders were 165 or above)
2. Should i be cleaning and or replacing anything else while doing this?
3. Where is the best place to buy this part, and the most economical
Thanks so much in advance. Without people like you I would never attempt this myself. Your wealth of knowledge is greatly appreciated
