Have an Indy XLT Special 97. I think that i may have a weak Coil. Is there anyway I can test the coil with a volt or OHM meter? Is very boggy and smokes (white) . is there any special carb adjustments I can do? Ran perfect last year with new plugs. About once a day I would have to change plugs because of very poor power and throttle response. Now I cant get it to run worth a dang. HELP ME OUT FOLKS!!!!! Thanks.

Strange.....Did you put diesel in it by any chance?
It has happend to my dad so don't say it can't. That will create low power, fouled plugs, and white smoke. Umm, I have no clue if you can check the coil or not. I dunno what else could be wrong?

Hows the coolant look? do you ever have to add any coolant? If you have to add coolant, and you dont know where it is leaking i would say you have a bad head gasket or cracked cylinder allowing coolant into the cylinders. This would also give white smoke and could possibly cause the plugs to foul. As for the coil test, you can buy an adjustable spark tester from autozone or the like for about 5 dollars (U.S.) and check between all of the cylinders for equal output of all coils. If you have a weak coil you will continiously foul out the same spark plug time and time again. The first thing i would do if the sled has sat all summer without fuel stabilizer is to drain all of the old gas out, clean the carbs and refill with fresh gasoline.

On a side note...you shouldnt have to change plugs that often unless you foul them out, in which case you need to rejet your carbs and or move the needle.

Have checked fluids. Havent drained gas but will tomorrow and post again. Not diiesel fuel. All gaskets are good, all 3 cylinders have about 180 psi of compression. Have SLP pipes. Maybe need cleaning?? Thanks for the help so far. Anyone know what type of jets i need for this sled? 97 XLT Special with triple SLP pipes??? Thanks.

Your jet size should be different from stock because of the pipes. You will need to get into contact with slp for correct jetting.
Also...if you have no coolant leaks and the gasoline is in good condition the smoke may be normal. What type of oil are you using...the oil may be producing the white smoke instead of the classic blue smoke especially if you are using synthetic oil. If the oil is causing the smoke it may also be fouling out your plugs...you may have an overly rich mixture. Check your jetting to be sure it is correct. Make sure your air box isn't plugged and make sure you exaust pipe isnt clogged with a mouse nest or the like. If this all fails you may want to check your oil pump adjustment to make sure its not over oiling the engine...(i have no idea on how to check or adjust it...maybe polaris man or erick could shed some info on that)
hope this helps...snowed today...triumph roars to life!!!!!

Alright Folks Thanks for the help so far. I tore into it yesterday and drained the gas and put fresh premium in it, drained the oil and put in Polaris 2 st. oil, drained and cleaned the float bowls, totally cleaned the carbs, counted turns of needles and air screws to specs, called SLP and I have the recommended jets. I also check my fluid levels (water and antifreeze), ran it for a little bit, and checked them again. It built up pressure like it is suppose to, and i didnt loose any. Brand new spark plugs yesterday also, AND STILL THE SAME SLOW BOOGY START AND BOGGY TOP END. I dont know what else to do. I took the coils off and took them to my local racing snowmobile shop and all three tested great. I am totally lost on this one. I still havent messed with the oil pump to make it leaner because i dont want to blow it up, but i think that is the only thing i havent tried.

You may also want to check the "E" clip on the needle in the carbs to be sure it is in the correct position. This probably should have been done when the new jets were installed. Also you may want to have the carbs syncronized to be sure they are opening at the same time.

just my .02 cents...take it for what its worth

Dood, when you checked the compressesion did you make sure all the plugs were out? I had a comp test on my motorcycle once and left the other plugs in only to find they were bleeding into the next cylinder through the head gasket. Make sure you had all the plugs out when comp testing. Just a thought.

BTW, I agree with XLTman!!

OK HERE IS THE UPDATE I have synced the carbs, new gas, coils tested perfect, been checkin fluid with no loss, did a cooling system pressure test with perfect results and no loss of psi, brand new plugs, jetting is correct. Still running really boggy and no low end, and it still seems like i have some moisture on the plugs. If the pressure test was perfect, how am i getting it on the plugs still HELP HELP HELP

I tell a lot of people this.

The low end troubles can maybe be easily fixed, following this:

Check how high the belt is riding in the secondary clutch. If it is not about 1 to 2 mm above the sheaves, there is a cam on the side, loosen the 3 bolts and turn it, I think clockwise. Then tighten it back up and take it for a spin, then see how high the belt is riding. It should be 1 to 2 mm above the top of the sheave. This will greatly improve bottom end. If you make it ride too high the belt gets too tight and the belt squeals when the machine is idling and it sometimes even drives away at an idle.

Try it out.

Have you checked for vacumn leaks, spray carb cleaner around base gasket and crank seals while engine is running. Also did you check the pilot jets for gunk while cleaning the carbs??
