I have an 83 cb125tdc superdream that despite my best efforts I cannot get it to run properly.
It has decent compression 120psi LH cylinder 130psi RH cylinder, and has good spark on both plugs, valves all adjusted correctly and timing marks all line up.
When I try to start it from cold and on the choke, it turns over for ages before it fires, when it does it just about explodes revs straight up to 6/7k revs then dies as soon as I try to back off the choke. Sometimes it will run thereafter after a lot of turning over again but there is a noticable weakness on the right hand exhaust compared to the left and right runs hotter than the left.
I'm lost for ideas what to check next Looking for some guidance on what I could check next to get it going again.
Thanks
Alan
