After siting for a winter carbs will offten get "gum" in the them. this is just from the gas being still in the carb too long. it is important that carb be removed and cleaned thuroughly. the carb has what are called jets. these are small brass toobs, and these are the more than likely dirty and the reason for the poor idle. more specificaly the smallest one. clean with carb cleaner. ( i use Barrymans B12 chemtool, can be found at local autoparts store) reinstall the carb and test ride. at the end of next season it will help to turn the fuel off and drain the carb of gas completely

Rough idle smooth accleration

Check your vacuum lines and be sure your throttle body is tightened down. Carb cleaner spray can be used to find the leak. Spray it around the lines and gaskets (while the engine is running). If the idle speeds up, you found the area of the vacuum leak and the solution to your problem, possibly.

I was running it for the 1st time after this winter it was idling fine at high idle 1,200 rpm and i bumped the throttle and it ran really rough and will barely run at all, I just don't know what went...

sounds like it might have varnished gas in the system. I would change the fuel filter, clean out the lines with a good carb/fuel injector cleaner and fill the tank with fresh gas. I will run a little rough until the bad gas is run out. If this dont correct the problem then it might be in the fuel pump or fuel regulator areas.

Will not idle

Your carbs are dirty and need to be cleaned. A tank of bad gas or old gas can gel up the jets. You buy gas, drive home, and when you get there the bike stops idling. Light gelling can be fixed by draining the carbs (screw on bottom of bowl), pulling the fuel line off the tank, and squirting some motorcycle carburetor cleaner down the fuel line. Plug the fuel line back in turn on the gas and start up the bike. If that doesn't work, using the same procedure buy some Chevron Techron fuels system cleaner, pour directly into the carbs and let sit over night (also drain tank and heavily treat one gallon of gas and put in tank) Fire up bike and let run ,idle, slow drive for 5 to ten minutes. This will usually get cycle idling without disassembling carbs. If it still wont idle you will have to take off the carbs, disassemble and clean blowing through the jets and jet passageways.

Ttr90. starts easily and runs smoothly on choke. will not run smoothly or idle off choke. could this be bad gas? the bike has never been run hard, is stored inside and possibly suffers from infrequent use.

Remove and clean the carb. Sitting around can let the gas evaporate. This leaves a varnish residue in the carb. Remove the carb then remove the float bowl. Use a spray carb cleaner to spray into the jets and carb circuits. Remove the throttle screw and air screw and spray into the screw holes. The low speed idle circuit is the problem so concentrate on the air screw hole. Put both screws back where they came from and turn each until it LIGHTLY seats. Now back each screw one and one half turns. This is the factory setting. If the bike still does not want to idle, there is still some varnish or trash plugging up the idle circuit.

I have a craftsman 25 cc string trimmer with fuel problems. After winter, ran tank of good fuel through it and it worked fine. Added fuel (unknowingly with water in it) and it ran on a slow idle and...

You shouldn't notice a difference if you remove the air filter. So I would replace it. Also if you are using compressed air to clean or blow-out the carb. Be careful, its not recommended and could make it worse.

Spluttering/backfires on low throttle opening/struggles to build

yes clean carbs, use Berrymans B12 fuel additive in the gas, double dose run til hot, then put it away overnight. try next day. also change fuel filter if it's been standing all winter long.

you can try spray in carb cleaner too, remove aircleaner, raise slider in carb with finger or something and spray a bunch in there, let it sit overnight to get to work and try next day

also if fuel is old then get fresh

Will only run with full choke and absolutely no throttle.

Carbs gummed up. Need a serious cleaning or a full ruubers replacement/rebuild kit. Gas turns to gummy when left stting in the fuel bowls.

Use a couple of cans of Sea Foam.. best stuff in the world.

Rough idle

Have you had the throttle valve cleaned?

Here is the most common cause of surges and stalls, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
