I only used SCAR as a reference, not to give credit where it wasn't due. I knew you guys that have been doing this for some time would know what I was talking about. I used SCAR because anybody else that is newer to carb mods would most likely have read about "SCAR" before and would have an idea as to what was going on here. Just trying to make things easier to follow for us rookies.
Got the carb back together and the bike runs great. Nice snappy throttle response off idle now and runs well in the mid range. Didn't get a long enough run to really get it up there but should be fine. Either cleaning fixed the throttle issue or something was stuck/jammed. Either way it looks like no damage to diaphragms was done. WHEW!
OK Charlie, here's what got me to try this failed initial action in the first place. You had suggested to myself and others to do a jet cleaning(not by stuffing a rag in the carb lol), on another thread, to straighten out vibration issues that we are having. Carb cleaned and tuned now but vibration is still there. There has always been a RPM range that gets the right harmonics going and vibrated, not terribly hard but a good fast buzz through the entire bike. Last time I headed out for a ride it seemed to be suddenly worse starting at lower RPMs and increasing intensity with engine speed. Not the usual sweet spot. Almost like a weight fell off somewhere or a crack. Using automotive terms, like a flexplate cracked making a normal little vibration much more intense. It goes away instantly when the clutch is disengaged so it has to be engine related. Any history of that? I just don't want to be buzzing, literally, down the road and have some disintegrate.
