Question about 1987 Honda NSR 250 MC 16
I have no knowledge on there carb adjustment After cleaning carb and fuel system it runs good but no idle. cold start good. Choke becoms to much as it warms. Off the choke, all good ,
20 sec lator it starves of fuel. Choke and start great again. Off choke 5 sec starve of fuel.throw choke on as needed to keep running. Sled drives fine.Seems to be lean on the bottom end.And throttle is slow to come back down to idle
My guess is that its not the carb at all but it might be the gas line in side the tank is cloged to the point whare you need to have it on choke in order to pull enough gas to the carb which would be the reason for it not wanting to come back down to idle quickly or it could be the fuel pump is cloged and if you tried that already than the fuel adjustment is way off and will need to be adjusted while a friend or family is keepin it running
and if that is not the problem than email me.

I would have your compression tested, if its a two stroke, and you can use tools with out breaking things or yourself, pour a cup of fuel down the left hand side of the carb and take the right hand side of the carb off and crank it like mad, if fuel leaks from there you better get to a repairer.
other wise the idle adjuster is usually on the left hand side where the accelerator linkages are, it will be a screw where the linkage touches when the throttle is closed. not too hard to find if you have a light source.
Hope this helps.
If you want any more help just ask :)
