My project is moving along nicely. Cleaned the whole bike, got the front brake setup in working order, cleaned the carbs, replaced the battery. I changed the oil and filter, cranked it with no plugs and got oil pressure. Not bad after 19 years of sitting in a garage.
I re-mounted the carbs to see if it will run. It kinda started but was only firing on one cylinder, three cold headers. No spark on 1 and 4 and dry on 3. Cleaned the plugs, points and adjusted the points. I got all four to fire after some priming, but here is where I am at. It will only run with full choke and even then 1 and 3 (cooler) are not running at the same temp as 2 and 4 (hotter). It will not idle at all. Opening the choke causes rpms to drop and additional throttle does not help. Temps tested with the wet finger on the header test. So, I think it is safe to assume that the points and coil are OK considering that the two cylinders that are hotter are each on a separate coil and all 4 are warm. I did not use re-build kits on the carbs, just a good cleaning. My thoughts to are rebuild all four since all are lean (full choke) and 2 are very lean. Lean means more heat right? Am I one the right track? Any other thoughts? Also, I am ready to buy tires to replace the dry rotted ones. JCWhitney seems to have a nice selection. I am having trouble sizing though. My front show ML90-19 (goodyear) and rear is 4.50 H 17A 4PR. On the rear I can get close based on their sizes. Anyone run a more standard rear? On the front, what does the ML90 convert to in standard size. I search for some conversion and they all reference 90 series but two or three aspect ratios. IE: 90x90x19, 90x100.19. Anyone know what the ML90 might be? It looks like they used the first two letter to designate the aspect at some point in time. Jack
