Mine is still in moto mode -- i have been searching ebay(and other places) for a set of hubs that i can lace a pair of 17's to. The bike is totally outdated and is borderline too powerful for todays track designs, but the grin factor is so worth it when you twist it on a wide open GP type track. Of course with a CR500, you already know all this.
The SM conversion is in the back of my mind, but my main chore now is to sell my 250 2 stroke and replace it with a 450 for general purpose riding (but as much as 2 stroke 250's are depreciated now - i may have to keep it for a spare "buddy bike" if anyone visits
