Alright I'm the proud owner of a yahama rx50 it has the same PowerPlant as the ysr50 but looks like a "cruiser". The bike had been sitting in the back of my garage for to long so I decided to fix the throttle cable and take it for a spin.
Long story short it's running like shit it bogs and bogs until you get into the PowerBand then runs like a runaway train.
The bike has always had stupidly low compression. You could push the kick starter down with your pinky finger ( I'm dead serious). It also has a oil injection system that seems like a ticking time bomb. Tops out at 35 but should go 55
The bike was sitting in a "shed" most of life's and still has the original tires from the Mesozoic age, I have had to put near 500 miles on it and have somehow not busted my ass.
It's sad to pull a bike apart at the start of summer but It really needs it. I am going to try to keep a consistent build thread going on it but no promises.
Thanks for reading, please send a prayer out for parts availability.
