[QUOTE="snowflake, post: 185597, member: 152"] Those particular bikes were not known for being the most reliable, though the 450's weren't as problematic as the 250's. You will need to keep close tabs on your valve clearances, don't worry, its not that big of a job to check and shim them, however, once you start having to shim them know that they are on their way out and its time to spend the money either on stainless steel valves, or, so I've heard, a head from fastheads with the beryllium seats.
