Original Topic above moved to here where the discussion should be.
I'll try to summarize once more my problems and then any help you guys can give, would be appreciated. There are a few postings I have done previously trying to get this bike running. Some are irrelevant as a number of things have been done and redone since those postings.
I started this riding season discovering #3 cylinder was not firing. A compression check revealed low compression on this cylinder, which was ultimately cured by new rings and a valve adjustment.
Compression now sits at 150 even on all cylinders.
Bike will start and run on cylinders 2, 3, and 4. #1 will only start to run at higher revs (i.e. 4000 RPM) Bike sputters from a stop and doesn't even out until 60-70 km/hr
I took the bike to a second mechanic as the first guy was unable to fix the problem. (He was a friend and I worked with him to do all the work up to this point, mostly him, not me!)
We replaced the intake boots and the O-rings. The airbox has been sealed around the covers as a precaution to there being a leak there. I am reasonably cofident that I do not have an air leak. He took the carbs apart and cleaned them (although I am not 100% certain he did everything from the carb cleaning series on the homepage). The bike runs marginally better than when I brought it into him, however as mentioned the carbs cannot be synched at this point. When he tried to sync the carbs, he could not get them to be even. His response to me was that the carbs were no longer servicable. No specifics as to why just that they were worn out. He replaced a couple diaphragams from a junked set of carbs and also replaced the needles with new ones.
The question really is, do you think these carbs can be made servicable or am I better off trying another set? Is it worth spending the time to clean them myself? I certainly have limited mechanical abilities.
