great product

Ape's manual cam chain adjuster helped to resurrect my KZ550A4.  A great product from a great group of people.  Glad to see they're bridging into off road applications as well.

I am not sure I saw one for the 2007 model YZ250F. Am I correct in that assumption? It looked to be listed for previous years; but, no later than a 2004 or 2005 model. Thanks. Oh, and if one can be obtained for that model year (2007) is it extra money?

I spoke with APE. The kid that answered did not know. I did look up the part # for an 03
5TA-12210-00-00
and an 08
5TA-12210-20-00

Same part. If you ordered an 5TA-12210-00-00 from Yamaha, you will get an 5TA-12210-20-00 . The difference is a superceded part. Can be an internal change, can be merely paint color. But they are interchangeable mechanically. So... an APE #YT1000 will work fine.
