[QUOTE="SRAD97750, post: 142761, member: 425"] I thought so too. But the bike never ran right. Cleaned and fiddled and adjusted. Nothing. Just wouldn't rap out. Swapped in the carburetor from the KDX200 (perfect fit) and the YZ ran perfect through the powerband. Carburetor issue solved. Get a new carburetor. :smirk: What can I say? I'm an A+P Mechanic... "remove and replace" is our nature. So I got my hands on BK's little package. And I was impressed.:wink: [ATTACH=full]17108[/ATTACH] Thanks buddy, I hope your truck is nice and clean now... :naughty: [ATTACH=full]17109[/ATTACH] And BOOM goes the dynamite! [ATTACH=full]17110[/ATTACH] Also, my new light bulb, my new one. And a super cool blue anodized front brake reservoir cap. [ATTACH=full]17112[/ATTACH] THANKS BUDDY!!! Much appreciated! Getting in to do some serious cleaning and measuring. I have a fresh top end gasket set as well.

Both the head and the piston show damage. Makes no difference, everything else is in spec.
