Hello, I just picked up a YT125 not sure what year yet will post when I figure it out. Here's the story below.
Picked up YT125 and a YT175 from craigs, have not touched the 175 yet.
Just started working on the 125, well I have to back track a little.
When I got them home, the recoil on the 125 would stick about half way took that off and got it working the prowl spring was broke so I pulled a good one off the 175, installed the recoil and checked to see if the 125 would turn, Yep turned pretty good, opened the gas tank and the gas smelled good so I tried to start her, no luck, check spark, no spark. I could tell it had been in water and then the last owner must have let it sit....there was a brand spark pulg in it so I knew they were trying to get er going. When I took the recoil off I could see corrosion from the water, I don't have a flywheel puller for it so I bought some WD electric contact cleaner tipped the Tri-Moto on its side and sprayed the heck out of it and let it soak over night. The next day I tipped the TRI upright and let the WD drain, then blew it out with my compressor and then sprayed it one more time and let it dry over night.
The next day I checked for spark, and Yahoo, strong spark. now I checked for compression and she is right at 100lbs.
So, next I cleaned the carb, changed the gear oil, well there was no gear oil, so I filled it drained it and filled it again.
Next I filled the oil tank, cleaned the pet cock and tried to start it no luck nothing at all. the next day I tried push starting it and after about a minute and full throttle she fired and died. Tried again and started right up but only with full throttle and I could keep her running and she would almost idle, in neutral, when I popped in first, I would have to punch it to get the rev up, she would crawl real slow then start to clear out and run pretty good till I slowed down then it would just bog down. I did put mixed gas in it and I had oil in the tank so I figured maybe she was getting to much oil. Today, I drained the gas tank, added fresh gas, added some more oil to the oil tank and blead the injection system. drained the carb and cleaned it again set the jet to 1 and 1/4 out and tried to pull start, got nothing at all, even tried starting fluid, still nothing, New plug, still nothing. set up a drill so I could crank er over that way. after a few try's she popped but again only if I had it at full throttle, I ran it a little but it looks like the injection system is not working, the oil gets about half way to the carb then stops. I think the float height has to be adjusted, and I messed around with the injection a bit with no luck. What do I do next? thank s, sorry if I made this to long. I will have some more pictures up soon., Think I have one on my profile. I'm new to forums, might take me a bit to see how its done.263107
