I am going to change the spark plug on my 250. First of all, where is it (lol) and what should I use as a replacment? Anything that people have had good luck with? Also, what oil should I be running? I am starting to get a little low, so it is time to buy some.

 

the spark plug it should have is the NGK BR8ES.

 

clicky here for parts Polaris 1996 Trail Blazer 250

 

we used synthetic 2 stroke in our trailblazer. it cuts down on the smoke and the smell. the plug is in the head top of engine.

 

i only run the pure polaris - stroke, it runs the best this way.. i put a qt of some valvoline in it cause i did not want to make to 40minute drive to the dealer to re-supply.. this thing ran like crap, i got about a 1/2 gas and started noticeing the difference.. i ended up draining all that oil out and went to the stealer that polaris stuff aint cheap... long story short i re-filled the oil and bleed it ..ran fine again.. i have a yamaha snowmobile and its the same way if you dont run yama-lube ,that aint cheap either... hope i could be of help.............................

 

I know what you mean. I have a Yamaha 30 horse outboard on my boat and it runs like junk without Yama-Lube. How much is the Polaris stuff per quart? How long would a quart last me?

 

i have had the bike 2 yrs and it gerode alot in the summer and some in the winter also, i probaly go throiugh 2 or 3 qts a year.. dont really use a lot of oil .. i think about 7-8$ a qt.. put some valvoline in a i dare you( dont just kidding).. i also run the ngk plug it does not like champions either.. my yamaha sled dont like chams either ,, runs like a mother--- w/ ngks go figure...

 

so what happens if I put yama lube in my 250 trailboss?

 

I would run a champion RN4YC and polaris ves gold synthetic oil. Plug costs 2.40 and a gallon of oil is 34.00 a gallon.
