Question about 2005 Suzuki Boulevard C50

1 Answer

Suzuki C50 Boulevard (4k miles) backfires during deceleration when under pressure. (the clutch handle is not pulled or it has just released.) It really gives one loud POP! The rest is the usual sounds of stock pipes.

Backfiring when the throttle is closed shows a lean mixture. Either you, or your mechanic should take a look at the mixture, and there's a 99% chance that that was the cause of your problem :)

I have a 2005 Suzuki boulevard C50, it starts just fine in neutral but when I shift into first gear with clutch handle pressed it pulls forward real hard and then dies. Tried adjusting the clutch cable but...

Hi, this is a clutch adjustment issue. If you have maxed out the cable adjustment at the clutch lever, you will have to make adjustments down below, where the cable contacts the clutch cover. There's a million YouTube videos that will walk you through the process. If the bike still pulls forward when the clutch lever is engaged then your cable has probably stretched past its adjustment range over the years and needs to be replaced.

This spring my bike ran great for 200 miles, than began lose power and backfire. I took it to a dealer and they cleaned the fuel injector and then it ran great for about 4 mo. Now it is doing the same...

There is no filter, but a screen over the fule pump intake in the tank. You could put a filter into the line from the tank to the injectors, just make sure that there is no leakage under pump pressure.

For pollution control, the bike is equipped with a pair valve. It injects air into the exhaust to burn wasted fuel. Many companies sell block off plates to remove the pair valves since they are so annoying.
