[QUOTE="cleonard, post: 122725, member: 21"] One thing about the engine. The YZ490 and by extension the WR500 were well known to have detonation issues that were almost impossible to jet out due to a less than optimum combustion chamber. There is a machining mod that makes it much better. Any idea if that mod was ever done on the head? [/QUOTE]
