2003 KX 250 SF Conversion
umberto:
I got my shifter issue fixed by swapping out an OEM 2004 shaft and putting a new shifter on the bike. It now shifts like a champ. I went over to Danger4U2's track and did some laps, but the motor still just doesn't seem happy. It doesn't rev cleanly under load, and I'm pretty sure that the jetting is very lean. It's a shame, because the rest of the bike works so well. I posted in the jetting section, but if anyone has any suggestions on where to start with the jets and needle position I would love the help. Thank you!

Thank you! I'm still having some issues with the carb. As soon as I get that cleared up I will post a ride video so you guys can make fun of my riding. :-D

So I got all the stock jets in for my carb and got them installed, but now I am dealing with another issue that is familiar. When I was riding at Danger's place, the bike died as I was finishing up my test ride. I couldn't get it to start again, and it felt like it didn't have spark. I pulled the bike apart (one of the joys of the SF conversion is no room to do anything :-D) and did a process of elimination. The compression check came back in the 180 psi range, and there are no unusual noises or vibrations. The carb is flowing fuel, and the plug is new. So I checked for spark at the plug, and of course nothing. The OHM test revealed no flow through the plug wire, and the main wire was out of range. This is the second coil I have had on the bike, and the second fried one. I noticed that my mount was a little crooked and it is letting the end where the plug wire comes out touch the head a little bit. Do you guys think that this is causing the fried coils, or should I just replace everything and start over? I worried that something upstream is frying the coils and I am just putting a band aid on the problem.
Thank you again for the advice!
