Here's some updated pics. Everything worked out pretty well. Had to retro-fit a few KX450-250F parts but not a major pain. Now that it's all done, I'm considering the AF frame conversion this next winter...
My stock tank was looking scabby so I wrapped it with 3M Di-Noc carbon fibre. Has anyone tried this stuff? It moulds very well and now it looks like I'm sportin' a 100% carbon fuel tank for about $20. We'll see how it holds up. I'll take some pics and show it off soon.
As for my buddy and his SXV550... I've slapped him and taken his lunch money every time we are out together. He's so pissed the old girl beats his techno-savvy Italian Stallion
