Hi all. I have just purchased a 1985 Suzuki GSX 550 EF, at the bargain price of $650 and in condition good enough to ride away!!! First things, I did were replace plugs, oil, oil filter and air filter. Bike was idling badly (if at all) when cold, the choke is not reliable, and when warm still has no power below 3500RPM. Apart from these issues all was good until I decided to try adding some carb cleaner to the fuel. The morning after, my bike would not start, and no fuel was getting to the engine. So, next step is to find a friend with more mechanical smarts than me, then remove the carbs, to clean the jets and float chambers. When we reach this stage you can see carbon buildup on one of the 4 Throttle valves. Before I reassemble the engine is there anything I should be worried about, or anything I should do? Thanks in advance, and glad to be with you all on the forums!
