Yep me too I'm one of those "closet I use AVgas too" users. Yea I've heard all the horror stories, and never had a problem or fouled a plug. I mix mine at 1.5 gal to 3.5 gal pump. btw I use the 110 octane, did you test or ever try that? My 97CR250 pinged bad when it was stock, mixing AVgas cured that problem for what it's worth.
