Dude,
Take a deep breath, a step backwards and regroup. I've spent thousands on hair brained ideas, some worked some didn't but I never let it discourage me. Some of what I've read about your build was to lose some power to make it more rider friendly, if that is the case don't worry about the stator, in fact if the goal was to make a good trail bike I wouldn't have ponied up for the carb either, get it together, ride it and have fun, believe me you can have as much fun with 60 hp as with 65hp. Hinson quit making clutch baskets several years ago, there may be some around as surplus, I have one and I can say it has held up incredibly. I wouldn't buy a Pro X unless I really needed a new basket, I would go for the Talon it is a nice basket as well.
Kaw rider mentioned 4.4, it was good stuff but in a 2t I would use the Q16 or maybe the MR12 (about $25 a gallon but helped us win a national championship) for the trail rider/play rider I would use something like vp C-12 or equivilent. Oh by the way I have part of a barrel of 4.4 that somebody could have for free if they come and get it. I'm in MT
