Is the yz 450f's engine pretty much the same as the 250's in regards to engine maintenance procedures? I went to thumperfaq.com for some reference for my 450 but it only showed information for 250's? Wanted some pic's. of a valve clearance inspection.

Basically yes, but I'm sure the actual clearances are different. What kind of pics are you after? I'll send yo u a link with a bunch of pics of my 426 apart when I did the 450 cam mod :naughty:
