Check the cam shaft. The exhaust lob is the weak spot. They will wear down to nothing.

SOURCE: 2003 sportsman 700. no spark at plug. off/ run

Have you been running the bike with a low battery? Have you changed the spark plug? Have you checked that a fuse isn't blown? Check these items if all is good, chances are that the pulse coil or pick-up coil is shot, could also be the stator. Have someone who knows how to check it for hons of resistance.

SOURCE: my 2001 polaris sportsman 90 is having problems

Had the same problem with my 2001 sportsman 90. Weak spark, sometimes no spark, would only run for a few seconds, ect. I found a partially burnt ground wire coming off of the coil. the coil is just above the carb mounted on the frame. Mine was the small black wire on top of the coil and it fixed the five second stalling problem immediately.

SOURCE: Polaris 500, starts fine but when you give it gas is stalls

check the exhaust lobe on the cam. these are prone to wear if oil changes are neglected. try to run it with the airbox lid removed and see if there is any change.

How do I adjust seadoo RFI mixture?

There should be an adjustment screw that looks like a "t" on the side of each carb. Screw it in 1/8th turn at a time to lean it out. Too much and engine detonation. I would recommend getting the retrofit kit to block off the oil tank and run mix fuel. Then there are no issues with too lean/rich, oil pump failure, plugged oil filter, broken or collapsed oil lines etc.

2010 sportsman 500 hd runs then dies turns over won't start

My opinion, it's running rich and letting it idle for 5 minutes doesn't help. Whether it's carbed or EFI, when the machine is cold, it needs more fuel. As engine temperature increases, it doesn't need as much fuel, and the carbon that started building up on the plug is burned back off. When a machine isn't ran for very long, carbon deposits continue to build on the plug. The carb itself may need to be rejetted/adjusted, it it's running rich,

Keeps fouling plugs

3 things are the main causes of black soot. 1 not enough air, check air filter. 2 running too rich, lean out the carb. there will be 2 screws on the carb 1 to increase idle speed and 1 for air mixture. While running turn the mixture screw in until it sputters then back it out 1 turn. 3 bad timing. If the mower hits a rock or branch the shear pin can get creased and change the timing(it is to protect the crankshaft from breaking) Here is a link to a youtube video showing how to change the shear pin.

My 04 harley night train keeps fouling plugs left and right i richened the mixture with a 52 pilot jet. ran fine for awhile then fouled again could this be an electrical problem?

A #52 pilot is a bit on the rich side in my opinion. I usually use either a #48 or a #50 but each machine is a bit different and your location effects it as well. I wouldn't think an electical problem is the cause or you'd notice erratic engine performance prior to the plugs fouling such as misfiring, coughing or spitting back through the carb. How long are you running the enricher when cold starting the engine? This is the biggest reason I see for fouling plugs. People will start the engine with the enricher and allow the engine to run while they put their riding gear on, sometimes five minutes at full enrichement. This will foul the plugs quickly. The enricher uses a different fuel circuit than the normal running operation uses. It draws fuel directly from the float bowl and it's a very rich mixture. Try starting the bike with the enricher and once you can keep the engine running with the throttle, turn the enricher off. Use the throttle tension knob underneath the throttle to hold the throttle open enough to keep the engine running until it warms up.

Good Luck

I have a 1995 Honda 750cc Magna. I have to change spark plugs about every 100 miles or it don't start.

Here's my $.02. Your plugs are getting fouled cause the bike is running rich. Adjust the air/fuel mixture screw to make it run leaner.

I just got a 2000 zr 7 and it has good compression but smokes after a few minutes of running. The far left cylinder fouls the plug, as I said it has good compression, but has been sitting for 3 years, how...

What color is the smoke? A blue-ish smoke is burning oil, a blackish smoke is unburnt gas. If the plug fouled with gas or oil? Does the plug foul at idle, or while riding it? Full throttle? or partial throttle? Answer those questions and you will know if you have a an oil leak in the head or overly rich mixture at idle, or during an open throttle position.

It sounds like too much gas (since you say it has good compression -- did you do a real compression check?). I'd get the carbs synch'ed and make sure they all have their idle mixture screws set correctly.

Spark plug fouls out after 5 minutes of running

If plug is sooty, this is due to mixture being too rich. This can be caused by dirty air filter,
Clean or replace the filter and if this doesn't improve the situation, adjust the carburettor to ensure the mixture isn't too rich.The procedure for this is to turn the adjustment screw (if there is one present) slowly anticlockwise until engine almost cuts out, then turn the screw clockwise until engine almost cuts out. Set the screw halfway between these two positions.
If the plug is black and oily this could be due to engine bore wear and oil getting up by the piston into the cylinder (in the case of a 4 stroke engine) or due to an excess of 2 stroke oil in gas (in the case of a 2 stroke engine) Gas / Oil mix should be in the ratio of 50:1

I have a 85 gsxr 750 running rich on the left

Hi Chris,
You will have to recheck the float level (in the float chamber) of those two carburators, reset if necessary.
You may also have to reset the air-mixture screw for both of those carbs. Standard procedure to set htem is tighten them all the way in making sure not to over tighten to avoid damaging the sharp end of the screw, and thn to open 2 and a half to 3 turns.
You can thn reset them as the engine is running + -- either way.
Hope this helps!

I have the Suzuki GS 750E, the spark plugs are constantly becoming fouled, how do i correct this problem

sounds like its running to rich, check your air filter is clean, set your carb mixture ,
turn the screws in untill they bottom out ,but dont turn to hard !(they have a fine needle point end and are easy to break leaving the broken point inside the carb making adjustment impossible )back all four screws out 1.5 turns and start from the bike and adjust from there to rich turn out to lean ( weak turn in ) a good web site for these bikes.

good luck
