I started my 2000 suzuki Marauder today after it sat for 4 or 5 months and it started, but idled very high and alot of crackeling from the exhaust pipes and then where the pipe meets the engine, smoke started coming out, so i shut it off and it backfired. What the heck just happend?

Hi, Could well be carburetor misadjusted. Too much air to fuel mix
Also if the bike sat for a long period, it may have gummed up jets in carb. Clean out and you'll be good to go. Hope that helps.

The engine on your 2000 Marauder 800 is the same 805cc engine as on my 2006 Boulevard S-50. They take two spark plugs, one per cylinder near the exhaust ports. I recommend NGK- 5129 gapped at 0.035 inches.

The only other factor is the throttle cable. See if there's an adjustment at the handlebar.

If the bike ran fine prior to putting it in storage and all you did was drain the fuel and disconnect the battery, its likely moisture ( condensation) developed in the carbs while it sat. this type of thing happens when fuel is drained. Your best bet is to remove the carbs and clean the jets. Its my opinion and experience to put fresh fuel in a bike along with (stable) fuel treatment prior to storing them. With the stable added to the fuel, the fuel will hold good for about 1 year.. Replacing the battery and starting them and letting them warm up to operating temp monthly while in storage is always a good idea..
I hope this helps..

This is fairly normal for the model Suzuki you have. Because of the manual choke, of course you have to do this by hand as you are doing. Newer models have automatic chokes.

Be sure the wires are hooked up, and it may not have gotten hot enough to turn on the fan in just a few minuets. Ride it close to home, up and down the street for a bit to see. Just do not go far until you know for sure.

well 1st budy try a new plug sometimes the case and get back to me if no change

hi your exhaust is a sealed item,also your bike is a 4 stroke,why would you need to clean the baffles?only reason these would block up is if you are burning oil,if you are then i would think about a top end overhaul
