My 2000 M2 has been sitting for a while-probably 2 or 3 months of the same gas, the odd, brief 'maintenance' ride every 2-3 weeks. All of a sudden, I'm not that surprised, it only runs with the enricher on continuously even after several minutes, and stalls at at anything under 2k rpm but seems OK at speed-short run to the corner store. I have a wing nut on neg. battery post- never know when I may need to ride-and neglected to eliminate the gas supply to the carb. drain gas from, etc. for moth balling as I usually did in the past. I'm planning on doing the popular $12 needle/slow jet mod. to keep the carb from farting, (as it has been doing so a lot in the past 6 months) but I would like to get it running reasonably well before I do this as a kind of 'control' from which to begin. Sorry for being long winded. What would be the most likely cause assuming that it is stale gas- ran fine 2 wks ago? And is there a quick fix? I'm already draining the tank, blowing through the lines, etc. Next step take bowl, float off and give it a quick, lite blast of air, as this worked before. If it runs crappy after this- my gut tells me it might not- what would be your next move? PS, new intake gaskets, etc too- could it be an intake leak or loose exhaust bolts? Any other recommendations after I've got it apart short of big bucks parts? Thanks. | ||

If it has spent a lot of time sitting, I would start with fresh gas and a carb cleaning (since you will be in there anyway). My experience with a KLR-250 carb (very similar to your M2 carb) was that everything needed to be cleaned inside that carb. The first time I just cleaned what looked important, and that helped, but it wasn't fixed until I pulled it back off and cleaned everything I could find in there (no matter how insignificant it looked). | ||

The reason it runs with the choke out is because the idle jet is clogged. If it still has the stock idle jet, get a #45 jet and install that instead of doing the following. Take off the float bowl and remove the idle (slow speed) jet. If the jet is clogged to where you cannot see light through it, spray carb cleaner through it and take a strand of fine copper wire and poke it through the jet. If you can't find copper wire small enough, use a fine sewing needle to poke the jet. Put the carb back together. This will get the bike running well again. Next time you store the bike though, put some Stabil in the tank. | ||
