    Tri Moto 125 Spark plug is getting oil on it

    I got a seized up tri moto 125 from my grandpa. I ended up pouring a bunch of oil, lubrication and finally got it unstuck! I can get a great blue spark but once the spark plug is screwed in it doesn't spark because its getting oil on it. I sanded it a few times lightly and screwed it back in yet keeps getting oil in it. I tipped the machine completely over and no oil came out. How should I remove this oil? I heard a chicken bastor lol but is that really my best bet?

    If you spuirt a little gas in the plug hole, and pull the rope a few times, you'll rinse it into the exhaust where and it will blow out when it starts.

    You're also going to need a new plug. If you reclean a plug, you have to get the white ceramic insulatror clean which you cannot do with sandpaper. Only sand/bead blasting works.

    Normal gas if you have the injection & are confident in it, Premix if you do not have the injector or are unconfident it works.

    i would use premix to flush it also i forgot to ask but is the oil getting on the spark plug is it 2-cycle oil or is it oil from tranny side of the motor because that could mean that it needs a crankshaft seal.

    Hey old yellow wanna buy my YT? =) I have all my wheelers for sale now except my 200x, I'll sell it pretty cheap. At least what I would think is cheap for a complete wheeler.. its just a basket case at the moment. So you could put it together or use it for parts.
