Same thing happend to me last autumn. The advanced timing was way out... Strangely the engine sounds OK and runs fine, so I decided to run it this summer without any rebuild. Tough machines, they are.

No idea about the handle bars, but you have for sure mounted your tank badges the wrong way around;-) Now the fly backwards!

OK and thank's lm. By the way, what is the purpose of the air vents, i.e. ventilating what? Never seen this on any motor before.

Thank's for info lm. Will do some re-piping now. However, my air filters, both the original very old and the new from Apex Cykle, only have one connection each. Can I simply let the vents from the cylinder end where the pipes from the carb floats end? Have seen this on another Swedish bike.

Have a CB72 1962. From the cylinder between the carbs are two pipes (Air vents, pos 23?) connected to the inlet filters. On the top of the carbs ("Pipe, Power Jet pos 1?"), there should be some pipes going somewhere, but I only have two nozzels screwed in there, connected to nothing. Can anyone tell...

OK, that makes sense. Will check and revert regarding the positon of my washer. In late September, as I am on the road now....
