I see very little info about these carbs or at least I can’t find what I’m looking for. This is the one part of the bike that I have very little knowledge about. If you see in the picture the “air screw” has a stopper that only lets me turn it a max of just under one full turn. I’m not even sure if this is the proper screw but I read that it should be lightly turn in to stop then out x number of turns, also this has the mechanical arm which operates all the carbs, not individual cables to each carb so if I was to use a vacuum gauge to sync the carbs this is where I adjust the needle in or out ?? The bike runs pretty good, pops a lot on deceleration, I did try pods at one point but ran like crap so put back the air box since my limited knowledge of carbs kind of scared me off playing around with them. There is quite a bit of chain rattle at idle which maybe syncing would help. My plan is to tear the motor apart this winter to freshen it up, burns some oil, oil from oil tank leaks in to motor when sitting for a while, change cam and primary chains etc but I would like to know how these carbs work and what screw does what so I can tinker with it this summer and before I tear it apart. I realize these are fairly simple carbs but it’s something I’ve never taken the time to learn about so any info on these particular carbs would be great. Thanks in advance.
