OT: Motorcycle Guru's, Dual Carb Question Options

[saigon71]

My Ninja 250 (don't knock it till you try it), won't idle without the choke on at least part way (after warmup). There is a definate flat spot through the low RPM range, but once you break through it, the bike winds out well. It has been this way since it rolled out of the shed after winter. I have some sea foam carb cleaner in the tank, and while I have not been riding it a lot, things have not really improved. Idle jet clog?

Thanks.

Sadly, I don't think draining the bowls is going to help you. Very tiny passages are likely plugged. The only way I know of to correct this is a thorough manual cleaning. You can do it. Just take your time and write stuff down/take pics for reference along the way in case you're nervous about putting things back together the way it came apart.

Another thing:

Float bowl screw heads are soft. Make sure you use a good #2 screwdriver tip if you go to remove them. Once you bugger one up, it's a pain to remove the screw. A lot of times, I put a tip in a 1/4" socket and use a 1/4" drive wrench so that I can push into the screw hard with one hand while having the added leverage of the wrench to break them free.
