oooooooo god tri moto ?????s

[kevinhaine]

well.....i have a 1980 tri moto 125.....i cleaned the carb and the fuel system...its very hard to start and when i do start it a ton of white smoke come out and it revs super high for maybe 30 seconds and stalls out..help

[kevinhaine]

also i just got the thing and and they have been sitting for like ten years

[whipit]

it is running extremely lean , either some jets are messed up still or you have an air leak

[Unclediezel]

Double check the pilot jet in the carb---they are extremely small and must be --SPOTTLESS-----

[kevinhaine]

also im getting about 60 psi and 90 after i put some oil in the cylinder

[kevinhaine]

my frame #starts with a 4ud what model is that exactly...i put some oil in the cylinder and it started up perfect for about two minutes then stalled out agian..i guess i may need to rebuild the engine...or mabye just replace the gascets......please help......

thats low compression. I'd have to look in my book to be certain but i think its like 125 you want. Revving high would be an airleak or running out of gas. Spray some carb cleaner,wd40 or something like that around the head and base when its running and if the idle changes theres where your airleak is.

oooooright.......how about this.. does a leak coming out of the seal were the exaust and the cylinder meet cuase an air leak to be worried about and could that be my problem..how do i check if my oil injector is working properly

[Tri-ZNate]

by air leak they mean between the carb and engine. Does the throtle screw in from the top? If so make sure its on correct, if not it will rev really high like you said since it isnt down all the way.

my 83 ytm200 revs high only when outta gas soon.

60 psi lol, that's about 50 away from where it should be.
