[QUOTE="Ol'89r, post: 1286666, member: 17212"] Joe. It all depends on your riding style. If you are a fast intermediate or semi-pro then 60-80 hours is a lot. If you are a beginner or novice you could probably get away with more time. This decision can only be made by you. If the valves have only been adjusted one time, you could run them again and check the clearance often. If the clearance starts to close up faster than normal, change them asap. If you can't afford to buy the Kibblewhite set-up right now just replace the ti valves with new ones. They are about $35 bucks each and will give you more security than running the old ones. If you bite the bullet and go with the Kibblewhites, you won't have to worry about it. I personally would rather spend the time and money to do it right than have to hold my breath every time I rode the bike. If you do lose a valve it will cost you big time. In regard to the dirt in the carb. Dirt will cause more problems than just wearing out the rings and guides. The coating on the ti valves can be worn off from dirt entering the carb. Once the hard coating is gone, the valves will cup, (sink into the seats) and wear excessively. If your clearances start moving faster than normal, this is most likely the cause. [/QUOTE]
