A good question! I didn't do any of the aftermarket stuff- I bought it that way.
The bike did run fine for about 6 hours or so a few weeks ago and then suddenly didn't.
I have been trying to track down the problem since without paying $50- $75 an hour
in labor to get someone to fix it. I'm smart, I know I can figure this out.
(but a little help sure makes a difference!!!)

I don't think it's a jet problem because it ran fine before. I haven't changed anything on the bike
other than trying to track down problems and repair them. Whomever had the bike before did
some really shoddy work on it. I just didn't know it at the time because I trusted some friends
who rode that told me it was fine and it only had 2500 miles on it. Oh well!!!
