Huh? Nah, I'm a former 4 stroke owner... Though my exhaust "only" cost me 650 dollars, plus I had dumped money into cams, new springs and retainers, port work, etc... I was however looking at the new 4 strokes (EFI) before coming back to my senses (after looking @ the cost for the bike, EFI programmer, exhaust, new cams, etc...) and getting back into 2 strokes. I spent more time maintaining and worrying (yes, I worried. blowing a 4 stroke up isn't an if it will happen, but a when it will happen scenario).
At any rate, it's great to see 2 strokes gaining (by quite a bit in some areas) popularity again.
