I laid down some fresh paint on my 550 sx tonight. rattle can style. check it out. I still have to sticker it up. Pay no attention to the sea doo in the background, it's not a couch.

Ok, so I got my 550sx running great after replacing the exciter and pulser coils. but after I rode it for a little bit it ran like crap and didnt even have enough power to get me on plane. At first it ran awesome and made tons of power. then I got half way around the lake and it started to...
