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:

      Got a break in the weather over the weekend, and was finally able to get out on a track for the first time since October.  I know I suck compared to a lot of guys (and kids for that matter), but I always have a blast twisting a grip and roosting some dirt!  Here's a raw uncut lap around the MX track at IMI Motorsports Complex in Dacono, CO.  Was a fun day despite some wind.  Also, there was a drift car club having a meet on the road course.  So, got to check out some drift car action while we were taking a break.

      Lightly used Clarke Gas Tank (model #11614) for a 2010-13 YZ450F.  Includes cap.  For fuel injected YZ450F, so needs to have fuel pump transferred over.  Rest of stock tank hardware fits perfectly.  2.8 gallon capacity, so great for desert, hare scrambles, or WORCS.  Retails for $240.
