Hey guys. I just bought a Yamaha Tri Moto 125 in good condition. It was a barn find and was stored for 15 years there. I got it home, rewound the broken pull rope, pulled the carb, soaked it in cleaner overnight, completely dismantled it and cleaned each component, and reassembled it. I also pulled the tank and flushed it out. Once started the bike runs absolutely perfect now, but is a real beotch to start. Choke is working. About every 2-3 pulls it backfires and jerks the rope right out of my hand. It's getting excellent spark. New spark plug. After pulling it 10-15 times I can pull the plug out and it's not oversoaked. Today I pulled the baffle off to be sure it's not a clogged baffle. No change. I really don't think it's a carb issue because it cleaned up very nicely and now runs perfectly. I was told to change the rings but it seems to have good compression. I don't have a compression tester. It fires right up when pull starting it with my Big Red. The backfiring just adds insult to injury. I have blood blisters on my hand to prove it. I would very much appreciate some feedback on this from you wheeler heads here. Thanks in advance.
