Just got this bike and am ordering parts and thinking on things to do with it. It didn't come with a carb, luckily I have a couple pwks from my kdxs that I've replaced with lectrons, so I plan to use one of those while I decide if I like the bike enough to put a SC or Lectron on it.
While going through things, the piston was wrecked and had transferred a good amt of aluminum to the cylinder but I think the cylinder is ok. Either way it's getting sent off to Ted Boyko to do some work on it to improve bottom end as this 250 rotax engine is known for it's top end with an anemic bottom. The adjustable exhaust valve is interesting and I'm looking forward to playing with that.
The linkage-less rear suspension interests me for its simplicity especially for access to easily pull off and adjust as needed.
Opinions Needed-
I've torn apart the shock to rebuild and got exploded parts diagram from ohlins as there was zero information online on this model shock as it seems one off for this particular bike. The guy from ohlins said to use an ohlins shock oil that is 28cst, which seems heavy vs the Showa ss-7 (5w) @15.7cst that I use in my KDX shocks. I ride tight single track/enduro mainly, no mx track. Should I just stick with my 5w or move closer to basically a 10w?
I'm also excited about feeling the 46mm Paoili "blue steel" (essentially KYB) forks.
Definitely a quirky bike but I'm looking forward to getting it in good shape and seeing how it rides.

Brad, so very cool! Hope aggregations are minimal & the bike becomes functional with ease.
