I just bought a 1993 Polaris RXL650. It runs excellent except for a bog on take. my problem is PLUGS. Every day when i start it up for the first time that day i foul a plug taking off. i let it idle about 4 minutes before taking off and when i take off i keep at low rpms and a steady throttle position. after i changes the plugs im all set for that day but the same problem occurs the next day. i tested my battery and all is good. i run br9es. i was wondering if there is any special way to take off or if there is anything that could be fixed to solve the problem. Any sugg/tips would be realy helpful. this site is awesome and very helpfull keep it up!!

It sounds to me like you may be "loading" your sled up with gas. Put the track in the air and keep the revs up a little so you can clear it out. Letting it idle for 4 minutes eems a bit extreme i think you should let it idle for about 2 minutes revving it up a little at a time. The ride it around increase how much gas you give it as it warms up more. I think the key is, is clearing it out whens it starts up.

It could have to do with the temp. is still warmer the usually in Maine right now. Run a br9eya if your fouling plugs, how is the sled cylinder compression.

Is yoiu sled carbed or fuel pump? Thia is a strange prbolem because you said it ran better in warmer weather so you shuld generally richen the sled up a little bit cause cold airier is thinner making it run leaner. What i owuld do is RAISE the clip on needle one position and see how it runs this would drop the needle a little lower maing it run a little leaner. IF this doesnt work try changing your main jets or going to a different needle.

*cough cough* rxl...fuel injection

With that fuel injection system there has got to be some sort of air density sensor, begin with checking that. But first get a manual for the thing as it'll make fixing it much easier! Besides that you might want to try the BR9EYA as suggested, or a BR9EV or BR9EG...they are the higher performance, thinner electrode plugs

Win if you can...
Loose if you must...
But NEVER stop trying!

I dont know jack Sh!t aoubt fuel pumps. but as extreme said there should be an adjsuter on it. Try running a br8ev cause it s a hotter plug. i think you'll foul the 9's. But check and see if your fuel pump can be adjusted.

fuel injection. no carbs. when i said it runs better when its warmer i meant it doesnt foul plugs but when its warm out it bogs alot when it cold out it doesnt bog too much but it fouls plugs esier.

I just sold my RXL , you should be using the br9es plugs , when the machine gets flooded pull the white connector off behind the key cylinder under the hood ,pull once the reconnect that connector , the RxL waz bad for flooding
mostly when warm outside or after the machine had been running , dont wait 4 mins for take off , get on pull & go , thats the golden rule with the RXL , remember this because this stops continuos fuel from spraying into the engine
The Rxl waz a great machine will blow the doors off many of the new machines out there today , Had mine up to 120miles per hr on lake temagami last season mind you it almost fell apart lol , (not recomended )
If you have any questions email me @ [email protected]/snofan/../images/users/machz2000/POLARIS.jpg

I also own an RXL and experienced the same problems the 1st season. This is what I found. First I started with the air density sensor which is located on the right side of the air box , upon my brothers inspection he found a broken connector, we fixed that problem and it kept it from loading up when at an idle or slow trail speeds . But I was still having trouble fouling plugs . I took it back to the garage , did a compression test to find the stator side cyl. was low on comp. you should have at laest 125# per cyl. a variance of 15# is unnacceptable. I tore it down , the wrist pin circlip had popped out and scarred the cyl. wall along with catching the piston ring and tearing it out. Luckily I caught this before the eng. totally blew up , I still had to sleeve the cyl. Comp. tests are easy to do and could save you alot of cash.
