Spark plugs, Pipes and questions

Post by pgb123 »

Good people, my bike sat again for years untouched. I gave it a fresh battery, fresh gas and started it up. Runs, but A) won’t idle and conks out with a clack. B) loses power when I tried to ride up a hill in first. C) Battery doesn’t seem to keep a charge
.
I know i need to work on the carbs. I intend to clean the baffles, if I can get the screws off (which I can’t)

I’m curious what the following means to you experienced folk. Compression in left and center piston chamber is 130psi. Right side is 125. Left and center spark plugs seem oily, right side looks dry. Left, upper and lower pipes are black and oily. So is right upper. Bottom right is dry. Right pipe smokes a great deal. See pics and video https://www.dropbox.com/scl/fi/5xy692qm ... 3y6id&dl=0

Sort/clean/service the carbs & go for a long ride.
Think of how stupid the average person is, then realise that half of them are more stupid than that.
