Working away on reassembly of my bike, encountered a condition I thought I should pass on before I finish up.
My bike was garage stored for 20 years, a 1991 model with currently just over 20,000 miles. The PO had a shop bring the bike back to life before he sold it. One of the tasks was a carb rebuild. I had to remove the carbs to replace the hoses which I am done with and in the process of reassembling the bike. The clamps on the #1 carb manifold were both loose, both screws were misoriented. I put the new manifolds on the same orientation. Popped on the carbs and the throttle would rotate only a fraction. I thought some twisting may be causing shaft binding so off again. Throttle worked fine. Carbs back on, no rotation. Finally noticed the #1 clamp screw was interfering with the synch bolt. Off again. Turned out the #1 manifold was out of position by 180 degrees, putting the clamps that much off also. The misoriented manifold inspired the carb rebuilder to simply push the clamp heads out of the way and leave them loose. So, I fixed it, reinstalled the carbs, tightened the manifold clamps and the throttle linkage worked just fine.
When/if you do this job, note that the manifolds can be installed 180 degrees out and the index marks and locators are symmetrical. If the clamp screws end up between the 1/3 or 2/4 carbs, you will get interference with the throttle shafts that run between those carbs. The clamp screws should not be located between the carbs, but fore and aft.
So, there you go. Little problem. Short story. Long version.
