New take-offs on my old Sportsman

I’m looking at some new take-off wheels and tire packages on Craigslist. Is there anything I need to consider when choosing what take-offs to get? There are a lot of good deals for ATV and utv take-offs that are the same tire size I have but I’m but sure if the rims are the same offset. I have a 2004 Sportsman 400.

2001 Traxter 500XL wont idle up and backfires

My Traxter 500XL cuts out when reving engine. Can get more RPMs with choke on but still cuts out and backfires. Mine has not been run in 10 years. Gas is new, Fuel pump is new, carb has been cleaned professionally with new jets and everything is very clean and all wires look to be in place. Very low hours on this machine. Have not done the fuel filters yet because they are in the tank. Tried looking for vaccume leak by spraying carb cleaner did not find one. Any help would be appreciated!

Coolant for hot environments

Hey guys, looking for some advice. I have a 16 grizzly that notoriously runs hot. I run mud and water in south Florida where its hot, and typically find a place to dip her and cool her off, and YES I CLEAN THE RADIATOR Religiously AFTER RIDING, but when I’m dry riding she overheats. All the time. I don’t want to relocate my radiator if I can avoid doing so. I’ve heard there is a particular coolant that I can run that will help keep the engine a little cooler, and at this point anything I can do to keep her even a little cooler would be great. Any ideas on what this magic stuff is?

Thanks in advance 🙂

2008 sportsman 500 efi

I have fought with the wiring on this bike right from the start. most of the wires in the handlebars have been repaired/lengthened. NOW, it runs for ten minutes or so then shuts down, just like the kill switch was hit. the error codes are 55 and 58. i have taken the front end plastic off now and found one broken wire there and repaired it, no difference. the fan runs when hooked to 12 v. when started, it will idle for ~15 mins then quits and will not start, rolls over fine but wont start, checked plug, has fire.after it sits for awhile it will start again. the fan doesnt run during this test, im thinking it is shutting off due to high temp but there is no HOT display on the dash?? Sooo,my question is its either broken wires to the temp probe or a bad temp probe? were is the temp probe located? thanks to anyone who can help out.:angryfire:

Yamaha C.V.T. Belt Wear Open Discussion…..

During the time I’ve been a member here on G.C., I lost track of the number of threads started to ask about C.V.T. belt wear.

I’m opening this discussion to bounce a few thought around the membership to discuss what really needs to be known to determine ‘How Much’ is ‘Too Much’, ‘What kind of wear is bad’ and what is really going on under the C.V.T. cover. (Like which came first? The Chicken or the Egg.)

First, I decided to start this thread from a recent thread about belt wear on a very new machine, and the dealer replaced the belt when it looked like new, probably just to sell parts and service.

First of all ask;
How would a worn belt affect C.V.T. performance?, and is all belt wear bad?
When the machine is brand new, with near a 2.5 to 1 ratio, (remember I always recommend knowing ‘your’ actual stock ratio to understand future performance). The belt is not riding out of the secondary, which means it is riding high the primary. (Not near the collar the movable sheave sides across)
If the belt wears (narrows) 2 mm’s, it still doesn’t ride out of the secondary and does not bottom out in the primary, so if it doesn’t slip, what is wrong?

Many members add shim to widen the primary to raise the ratio which causes the belt to ride out of the secondary and lower in the primary. I say adding shim is like running a narrow belt, so in effect a worn belt is a good thing as long it isn’t slipping.

On top of that, some Grizzly owners machine material off the movable primary sheave which widens the gap between the sheaves the belt runs in, causing the belt to ride lower in the primary, higher in the secondary, like a worn belt.
Additionally, some members combine shim and machining, but still the belt does not slip. Then going to another level, I played with narrowing my belt while adding shim and using machining for max ratio and still the belt did not slip.

It is my thought;
Not all belt wear is bad!
Yes if you run aggressive C.V.T. mods it takes less narrowing of the belt to cause the belt to ride on the collar causing belt slip. Generally the belt rubs the C.V.T. cover long before the belt rides on the primary collar. I do know of one member that experiments with C.V.T. mods, for racing applications, that experienced the belt riding on the collar, but that was a very rare situation.

I feel most members need to be concerned about the belt failing from cracks in the material more than from narrowing of the belt.

Those that need to watch for belt narrowing are the ones running C.V.T. mods with the belt rubbing into the cover. Any additional belt narrowing causes more cover rubbing which eventually causes a hole in the cover.

I say ‘If it Ain’t Slip’in, it’s O.K.’
And if it is slip’in, find out why.
Is the belt bottomed out or is the ratio too high for the secondary spring.

If you want to know the difference between two different belt, install each and count the ratio with each. A worn belt will produce a higher ratio, but again if the belt is not slipping, what’s wrong with the belt?

Post your personal finding and lets see where this goes:)

Check your front driveshafts

Just a quick heads up, check the coupling that goes over the output/through shaft and the front driveshaft and make sure its tight. Apparently the bolt that holds it on backed off on mine and now I get to pull the motor on a 10 month old machine and split the cases it to replace that through shaft thanks to Can-am’s poor QC and terrible design. :th_smiliepissed: So check it out on your machines, and maybe it’ll save someone a big headache…..

99 Scrambler 500 Camshaft

Hi guys,

I have a 99 Polaris scrambler 500 with a worn camshaft and rocker arms. I know this is a common issue so was wondering if theres any aftermarket companys that make anything more durable? Does anyone have an extra laying around in decent shape they wouldn’t mind getting rid of?
