Question about 2001 Suzuki VZ 800 Marauder

1 Answer

I have a 2001 suzuki marauder 800, i have been having a backfire/ stalling problem. the baffles have been cut out of the exhaust and i heard this can mess with the pair system. i bypassed the system and tonight i had the same problem, however this time i noticed that the lights would dim and flicker right before the bike would backfire, and then the last time it back fired, i lost all key on power, checked all the fuses and while they were fine, i noticed several melted spots, and that someone had done a hackjob on the harness. any help or suggestions?

Hi, William and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a "LOAD" test "WARNING" you can have 12.5 volts or better but little or zero amps and the battery must be replaced.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

SOURCE: Exhaust Pipes on 1995 Suzuki Intruder VS

Hi Lcyr. 
Any changes you make to the exhaust system will alter the sound the bike produces. The more you cut baffles,and open up the exhaust, the louder it will get.  What you do alter to a greater extent,is the state of tune of the motorcycle. Any changes to exhaust or inlet plumbing will require a retune of the engine to suit the modifications. This can be subtle to dramatic. Opening up exhausts can often rob low end power where exhaust port scavaging is relient on some back pressure for maximum effect.
 Best to work directly with an engine tuner to do the mods that are known you can get away with, or buy aftermarket prebuilt pipes that have a known previously tested state of tune. Nothing worse than doing something, that then costs money to put back the way it was on finding out it didnt work as well as was hoped.. Hope this has helped you steer your custom mods a little.  I can say with certainty, that I have ventured to do what you are doing many times in the past, and it has always cost me more money in tuning and... and well more parts :)  Cheers
regards robotek

SOURCE: remove baffles from mufflers on a 1998 Suzuki VS 800 Intruder

there will probably be a couple or rivets close to the end of the muffler. drill out or chop off with a chisel. pull out baffles. but beware it will be loud. i did this to my dragstar/v star and ended up putting them back. you could just remove some of the fiberglass packing from the baffles, the cops will give you sh*t if you run straight thru. aftermarket pipes would be the real way to go, you may need to re-jet the carbs though. my bike also lost power with no baffles as engines need back pressure and all pipes are designed to give this.
hope this helps

How many spark plugs in 2000 suzuki marauder 800


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.

Many of the Suzuki's including Boulevard, Intruder and others have cut off switches in the kick stand. As long as the stand is down the engine will die when shifted into neutral.

I have a 2001 suzuki marauder 800 that just had cobra exhaust installed. what size jets should i put in it?


I purchased this kit for a 2003 Suzuki Marauder 800. Much to my disappointment, it did not come with any new jets. All it does is basically shim the needle valve using a washer. This is something you could do on your own. Just take the old washer and move it up 1-3 spaces depending on your elevation. Although this does come with new needles and washers, you could just use your old ones and acheive the same thing. It does include the tools to remove the plug for the pilot screw but again, you could probably do this with tools you already have. I am very disappointed i spent so much money on this.

Bike stalls out in neutral and wont start back up while riding


It sounds like the battery may be bad in spite of Auto-Zone's pronouncement. The connectors to the battery may be bad enough to make a poor connection to the battery posts. Is the battery water level up to the line in each cell?
Re-jet one step bigger as the baffle removal will make it run lean.

I want to clean the baffles on the exhaust of my 2002 suzuki


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
