I Need New Sprockets

[coryatver]

After having my 400 for 2 years the stock sprockets are worn out. The front one broke off teeth and there is only one tooth left and the back is pretty wore down.

I do not know much about sprockets and I was looking through magazines and there are like 50 different kinds. What kind should I get. I don't race or anything. I also plan on replacing the chain at the same time. So does anyone know of good sprockets and chain? And wheres the best place to buy or order from? Thanks ahead of time.

can't go wrong with sidewinders i have their new "survivor series" sprockets & chain, they maybe more $ but they will last you more in the long run! hope this helps

If you replace the front w/ a 14 tooth sprocket ; you will pick up a lot of acceleration. Only drawback is you will lose a little top end.

Acually I was thinking of going to a 16. I ride fast and my trails are pretty open but I think I will stick to stock. I was looking through my Rocky Mountain catalog and they have rental sprockets. Does anyone have renthal? What is the best chain to get? They also have a lot cheaper ones from "Primary Drive". There probably junk.

I bought Primary Drive sprockets from Rocky Mtn. ATV. So far, they are fine. They look exactly like the OEM stuff. I don't think you'd be disappointed in buying them. I have them on a strong running 85 ATC 250.

My Question: Anyone using a 40 or 41 tooth rear w/ the 15 on the front on a 400EX? I don't really want to drop a full tooth on the front and want something in between. Suggestions?

I pick my sprockets the same way I do my women... any teeth missing and I start looking for a new one.

Well I can recommend what not to get. I bought a Sunline sprocket for my 400ex (front one). After comparing it to the stock one....the Sunline one is VERY thin....I'd look for one that is the same thickness as your stock sprocket.

sduncan,
If they are pretty much the same as stock i think thats what i will get. I don't race or anything so i don't think i need gold teeth. For anyone else that might need sprockets hear is some prices i found.

From Rocky Mountain
Primary Drive front #36215 $6.99
rear #H01-HC0-000R $14.99
The renthals cost $21.99 and $49.99. Why do they cost so much more?

I also looked up the stock parts on Service Honda. The front cost 23 and the rear 56.20.

I know for a fact +1 1/4 swingarm you need 2 more links over stock length so maybe 3 at the most..

ive heard that Sidewinder Survivor sprockets are strong as heck!! thats what im getting when i need new teeth:D

[coryatver]

I ordered the primary drive sprockets and already got them. They look exactly like stock. I hope they last at least as long as the stock ones did. But i got the wrong chain so I have to send it back. I thought it was a o-ring chain but it wasn't and rocky mountain is sooo slowwww. I guess I am stupid becuase i have ordered from them 4 times this summer.

[400exRacerX]

Sidewinder makes top quality sprockets, and i am a high believer in "you get what you pay for" and primary drive sprockets are only like 6 bucks a sprocket, doenst sound like they would last too long.

[coryatver]

I just wanted something made to O.E.M specs.

["BLAHH"300!!]

Are you sure you just don't need -braces ?:D

i know this sounds kinda dumb but i saw a dude loose a race last weekend over this put your master link on the correct way...when it is on the top it should have the open end back...you probably know this but i figured i'd throw it in there just as a reminder;)

[coryatver]

Thanks a lot man. hey has anyone noticed the stock chain doesn't have a masterlink? :eek:
