I guess you could still consider my DRZ a DRZ. It's a 500 now, been that way for nearly 750 miles.
As the bike sits right now, it has a 97mm bore and piston, +5mm stroke, FCR 41 from a KTM 450, Yoshi TRC pipe, oversized intake valves with a port job on the in and ex sides (I got the head for $100 from a friend in Alberta Canada).
If it weren't for my good friend Dave, I wouldn't have the 500 though. He did way more work with me over the phone than I ever would have asked him to do.
Here is a pic if you all would like to see.
