    1994 yamaha xt225. its been sitting for about 6 months with gas in it, no stabilizers

    its an electric start. i also tried push starting it, it will sputter a bit and die right away. i drained the tank & carb and put fresh gas in. my next step was going to be pull the spark plug and check that, but i am guessing i need to clean the carb?

    thanks in advance

    6 months without a stabilizer is not a big deal.

    How's the battery? Give it a boost, prime the carbs on the petcock and engage the choke and start cranking.

    If it ran well only 6 months ago (if you're positive), then it's probably fine

    I would pick up one of these. They have leads you can attach to the battery so you don't have to pull the bike apart to charge it. You just let the pigtail dangle out of the way. If you are near a cyclegear, you can pick one of these up for $20 on black friday.


    I have had sucess with pulling the float bowl off of the carb and just spraying a ton of carb cleaner in there if there is just some dirt. I wouldn't waste your time with any kind of fuel additive to clean the carb out, you should be able to just remove the main and idle jet, clean them out and it should work fine.

    has a new battery, holds a charge fine (first thing i did). shouldve mentioned that
    should still pushstart if its just the battery (I've had this bike for going on 8 years, i know it push starts no problem, used to have to do it all the time)

    Check for hardened- rubber fuel lines. When gas sits in rubber it makes it brittle. If you have a crack in the fuel lines, it will be hard/impossible to get fuel to the carb...

    Tap on the carb bowl a bit, sometimes the float valve gets suck not allowing fuel flow.

    Wait, does the starter motor turn the engine over? Does the starter even turn?

    check if the plugs are sparking by pulling one out, connecting it to the cable, hold it against the engine case, try to start it and look for a spark.

    If there's no spark, check your coil.

    Do that first but you said it sputtered so that's probably not it.

    If you have spark then it's most likely something is gummed up from letting the gas sit too long. In only 2-3 months gas can start to gum things up. The petcock, filter, and carb can all cause problems when gas sits.

    I've had to drain the floatbowls when mine showed the same symptoms. i bought a cb400 really cheap that way once. I paid the guy 250 bux for it (and it was only two years old with 800 miles on it :lol: ) because he couldn't get it to run. I drained the bowls on the spot and started it right up the second time I cranked it. i road it off to my house and he stood there muttering to himself.

    got it to start today after draining the carb again. it seems like it is running super rich - the engine & exhaust got hot as hell really quick, and the choke gets it revving a lot damn higher than it should. i shut it off, let it sit 2 mins, wont start again.

    if it's running rich, your carbs are probably gummed up. Pull the carbs, drop the bottoms and look for gummy fuel residue.

    Check all the rubber bits as well. Petcock seals, rubber hoses, etc all get brittle with age.
  16. My XT runs VERY rich too. You're gonna need to pull the carb and clean the jet with carb cleaner and tooth pics or something professional... It shouldn't be too much work.

  18. Oh yeah. Were goggles when using spray can carb cleaner. Last time I cleaned my Xt's the cleaner went in one hole, out another and strait into my eyes. It felt great.
