I can't believe this rear sprocket!!!!!

[deathman53]

I have a 84r extended axle on my 86 200x, I ordered a 36t sprocket for it from sprocket specialists, there isn't even 10 hours on it, its half worn and it starting to hook. I used a new front sprocket and new chain, how is it that the rear sprocket is worn and the front and chain are like new. We aren't taling about a $30 sprocket here either, a $80 custom sprocket. I ordered a sidewinder sprocket today, most durable they have to offer. I'm gonna call sprocket specialist and tell them about this, maybe they will send me another sprocket??????

[Billy Golightly]

What kind of material was it made out of? If its an aluminum one its gonna wear no matter what...

[Dammit!]

How tight/loose is the chain? If there's more than an inch and a half slack with a rider sitting on the trike, that's why. When the chain is loose it has nothing to hold it down in the bottom of the sprocket groove so it ends up riding high on the teeth where they're the weakest. You can shark tooth them in a single ride on a powerful machine that way. Keep the chain tight and they last a long time.

[deathman53]

but not even 10 hours????? I had a aluminuim sprocket on my crf450r quad and it wasn't new and it lasted me about 5 months before it got as bad as ths sprocket did in under 10 hours of riding. By the way, the chain was adjusted right.

[deathman53]

I got a hold of sprocket specialists and they said to send the sprocket back to them and they wll send it to warranty dept. and look at the sprocket and possibly do something.

Try denniskirk. Their sprockets are decent

[deathman53]

try to find a 36t sprocket for a 84r, standard sprocket was 41t. I looked long and hard. sprocket specialists and sidewinder are the only places I found. I have to use that sprocket as my 200x had a 84r extended axle, and the 38 is not high enough, (1st and 2nd gear are useless with the 18" tires and this is even with a 14t front, I was able to do 3rd gear holesots without hesitation). The 36t works well with my motor and this is before the cam and 12:1 piston I'm gonna get.

[xman23]

yea i have a 35 tooth on my 200x, i think its a sunstart if that sounds right, but its been holding up real well

[86waterpumper]

this is why I say to just buy cheapo sprockets, like titax from rocky mountain or something haha even sidewinder high dollar ones will wear out, ask billy :P

[TimSr]

If it wore that bad, that fast, there was something wrong with the metal temporing or alloy. There is no way to wear out the rear sprocket without wearing out the front sprocket a lot faster regardless of chain condition, adjustment or anything else. A steel rear will outlast 3 or 4 front sprockets. An aluminum rear will still last 2-3 times as long as a steel front. Do the math. How many times does your front sprocket turn for every turn of the rear? Thats how much faster it will wear out.

[Billy Golightly]

Yeah even the Sidewinder Titanium sets will wear out, although I got a good 3-4 years of abuse out of mine.

I agree with Tim though, something was wrong with the material it was made from which is why I questioned, what was it made from?

[deathman53]

sprocket specialists said to take it off and send it back to them. I will take it off and send it back to them as soon as I get and put my sidewinder sprocket on. I couldn't understand how it wore so fast, either. I know it will be some time before they get back to me on wheather they are gonna send me a new one or not. That is why I bought a sidewinder one, I only have 1 atv and one dirtbike operating now, so the $100 is worth it for a few weeks of riding. I really wish I could get a steel sprocket, but nobody makes a 36t for a 84 250r. I don't have a stock or aftermarket 200x axle in my 200x, its a 84 250r extended axle, that is why the specail order sprocket.

[hrc85250r]

umm, sidewinder will custom cut any sprocket you want, reasonably too and quick.... i know they have a template for a 84 R....sidewinder chains are junk though dont even bother with those....sprocket seem pimp though...all of our drag sprockets are custom aluminum, we run a 56 tooth on the drag machine.... dont even bother with aluminum rears, last one i had lost teeth in a few weeks from some logs or something in the trails....

[deathman53]

I remember on my warrior, I had a aluminuim rear and it wore great, but I dumbly didnt use a skid plate and it hit the rr tracks when crossing and it cracked, by the time i got home, i was on 1/4 of the sprocket. this bike is for track use, and xc will have a skid plate, so I'm not too worried.

[hrc85250r]

i dont understand...why would you buy an aluminum sprocket when you could buy cr-mo or some type of steel sprocket when you know that they last longer( not generic steel) for around the same price?

Lighter...

[deathman53]

they are extremely hard to find in that size in steel, aluminuim was my only choice. I will buy a steel one, if it can be found. 84 250r 36t

[TimSr]

Sunstar makes a 15T front for that if it has the room up there to handle it. They have them at Bikebandit among many other places. It wont compensate for the 36T but it will get you half way there.

[deathman53]

thanks for doing your looking, but remember this a 86 200x, it just has a 84 250r axle. I just was looking and sidewinder's sprockets(I already ordered one, top of the line they sell for a 36t 84r) isn't made from aluminium, its made from a militay spec grade alloy, it is lighter than carbon steel and 1.8x harder than carbon steel, I think this sprocket should last awile. I know the reputation that sidewinder has for sprockets that outlast 3-4 sprockets. It just sucks that to get the sprocket off and change it, I need to remove the axle. I was assured that the sidewinder sprocket will last along while on this bike.

[hrc85250r]

Lighter...

this is true, but the difference for guys like us is not worth it unless you are racing pro.

[deathman53]

and the pro's tend to get new sprockets between moto's

[jason 32]

the alluminum ones are not regular alluminum ,they are a alloy they usually last longer than steel ones-- as long as they are the good allum ones and not elcheapos
check the chain !!!! ihave found that a bad chain will ruin a rear spkt faster than the front
what u check -is the rollers ,because they will shift the chain towards the front
and round off the sprocket
to check the chain for correct tension-- u really need the shock off to collapse the
suspension all the way other wise when u jump or ride 2 people it sits lower and
on some models the chain gets tighter with the suspension travel

my brother in law runs a 92 lt 250r,geared super steep for trails.he weighs around 300 lbs.he runs sidewinder stuff only.he buys the ti-moly series stuff. runs him like over 200 bucks for the whole kit.he gets about 2 years out of them. he runs their chains too.if he uses like a d.i.d. or rk oring x chain,his weight makes the links peel the sides off the chain. the side winder stuff is the only brand he can get use from.i have seen there stuff personally.it is pricey but it does hold up real well.

[86waterpumper]

Correct me if I'm wrong, but at least with the sidewinder sprockets I have purchased in the past, for a kawasaki kdx and klx 650 dirtibikes, the sprockets and chain both were not actually 520 they were something a bit bigger like 530 or something, I know a regular master link won't work on them either, so I would think if you were running sidewinder sprockets you would nearly have to run their chains as well. My sidewinder chains stretched plenty even though they said they were anti stretch, but I do agree they are beefier in thickness and on the sideplates than standard chain is. The sidewinder stuff without a doubt holds up better, but whether it's worth the extra cost depends on how much you ride, and how long you are going to keep the machine I guess. If sprocket specialists sprockets are that crappy, then for really odd sizes on most machines they are probably the only game in town.

[deathman53]

I was told that 520's work, but they recomend their chain. I will find out when I get the sprocket.

[mudbogger]

I had Sidewinder cut all of mine for my 350, I have had good wear on them to date, they have a bunch of new metals they offer as well for wear, etc.

[deathman53]

did you use sidewinder's chain or a different brand???

[TimSr]

I ran a Sidewinder on my TRX250R for a couple years I bought used on Ebay. I think I ended up shipping it to Billy when I got rid of my 250R stuff, syillin good shape. It was like a 48T or something. I ran a few different chains, and none of them were from Sidewinder. I know one was an ORing from Parts Unlimited. One was an RK Standard non Oring chain I ran in an emergency. Dont remember the 3rd one I ran. The sprcoket was in size #520 so the chains were #520. #520 means #520 and #530 means #530. You will get what you order, and you need the # chain to go with the same # sprocket. These numbers are industry standard metric measurements, and do not vary from one maker to the next. They may very well make a custom sprocket in size #530, as it will last longer, but it will be a #530 sprocket, that you can run any #530 chain with.

[mudbogger]

Yes, I purchased the chain as well from Sidewinder and it is 1 of theres.If my memory serves me, they are #530's but I may be wrong on that -if so they are # 520's and they made sure at Sidewinder that the sets matched.They were not cheap I'll tell you, it was a good penny for them for sure.
