I have pretty much decided if I run across a really nice used 07, for cheap, I'm going to buy it.
The swingarm on the 599 is totally different. I use the Pit Bull with the One Size Fits All, round protrusions. But I much prefer spools. KTMs come from the factory with bungs already welded in place. But on the 919, I've always thought if you got the hollow axle from n F4I, you could stick a rod thru the hollow axle, and make something work.
Nice, Sonic. You did well!
