My 450 will not rev out to top speed anymore ??
It used to do 90km on gravel roads no problem now it barely makes 50k any one help ?
I did chcek the filter and cleaned it it was pretty nasty,found water in the air box cleaned it out and a nnew spark plug but still same, would the engine timing be off ?
Hey sounds like you have been muddin and possibly drowned your machine at some point.
When this happens your clutch assembly can get jammed up with mud that gets washed in through the drive intake located under the front rack, it hardens and then the clutch will not open all the way,pull the cover off and have a look. You will need to clean and lube the clutch assembly with "Ultramatic Grease" then giver....
