I recently removed/cleaned/synced the carbs and noticed when I (and my motorcycle mechanic friend) were doing this, that 3 of the 4 diaphragms were showing signs of wear. Not having new ones, we reused the old ones. Still, after doing this, the bike ran better than ever as the carbs were WAY out of sync. Just recently, though, I've noticed that it doesn't run quite right. The only way I can explain it is that it seems like the timing is retarded (although I know that you can't readily adjust the timing). At the low end, it seems sluggish but runs okay (but not great) in the mid and upper end. At mid revs with a constant throttle, I notice some slight surging or missing. Could all this be attributed to the diaphragms having finally went? Like I said, the bike did run really good after the sync (for about a month now). Thanks in advance!
