Sprocket Replacement -
1. Set the quad up on its rear bumper... nose straight up in the air.
2. There is a plastic skid plate with 3 - 10mm bolts. Remove that. Careful you don't pull the hose off the motor.
3. You will immediately see the sprocket. Pull the bolt out of the end of it (14mm)
4. Slide the sprocket off the end of the output shaft and out of the chain.
5. Slide new sprocket on the output shaft and replace the bolt. I dont know how tight to get that bolt, but I dont remember mine being very tight. I put mine on tighter than it was to come out.
6. Put the skid plate back on with the rubber hose and put the quad back on all 4's.

Chain Adjustment.
1. Refer to owners manual. Very easy.

Should you turn off your fuel? (I can't seee why you would for fuel injection)

I bought the 700XX manual over the weekend, I'll post the recommended torque specs and bolt sizes.

Great job, and thank you.

I didn't. I did have a little bit of fuel come out of the vent for the gas cap, it drained on the floor but dried up quickly.

Great tip, thanks! :tup:

Where did you get your 13T sprocket from? Did you just buy the stock 450r front sprocket. Seems like a great cheap way for some low end power.

Rocky Mountain ATV has them and you can also pick them up cheap off of eBay. You can spend more and get the Honda one or you could spend a LOT less and get a Renthal.

Very cool. For anyone who has already done this, can you tell a bid difference in one less tooth? I know in a different thread everyone said it "probably" would be quite noticeable, but I'm just looking for someone that has done it and proven it to themselves.

I've done it on other quads and it was a much better improvement. On the 700XX it will make it to where you can idle in 1st gear while on it and not kill. It will also make it to where you can climb obstacles that you would have to feather your throttle and clutch to make it up.

5W0P has done it and loves it. I've been too lazy to change mine.

 

[TRX_Sixpac_700xx]

Sounds like I found my first upgrade! I'm waiting to do the big 3 all at once.

 

[scuzz]

Yeah, you can't beat that for $21 plus shipping.

Something to be aware of though, make sure that if you get some paddle tires that you stay with 22" tires, otherwise if you go with 20" tires (like I did) your gearing will be very, very low and make 1st almost too low.

So, when I have my paddles on I will stick with the stock 14 tooth front sprocket. With the stock tires on I'll have the 13 tooth. (once I get it)

 

[TRX_Sixpac_700xx]

Thanks for the suggestion. I don't think I would get any type of snow tires for awhile, whether they are the zippers with the short paddles or any other type. I don't get in enough winter riding during the snow yet to make it worth it, but when I do get the chance it is so easy to forget about the cold when you rip through a drift!!

With the Big 3 I can ride in gear while idling, Your bike will not idle with just the filter? If not the exhaust must be the big killer on these bikes stock

 

[TRX_Sixpac_700xx]

Stock mine will sometimes idle and sometimes kill the engine. I would think the filter would help.

 

[scuzz]

It will, just nothing like it can with the drop in front sprocket size.

But yes, the stock muffler is VERY restrictive even with the spark arrestor off and it sounding like a fart can.

 

[TRX_Sixpac_700xx]

I went to my local dealer today. They told me a stock 450r 13 T front sprocket is about $26.00 and the Renthal is $23.00. I wouldn't really expect there to be much of a difference between the two. Any idea if the teeth may wear sooner on one than the other? Since there isn't really a cost difference I think I could go with either one.

 

[5W0P3]

I edited the original post for my sprocket bolt size to 14mm.

I'm going to pop my stock sprocket back on today/tomorrow for our trip to red river saturday so i can see the difference.

Big 3 + sprocket = HOLD ON! Draggin on the sand, launching in second is almost 12 o' clocking the quad, so i let out, and get back on it and it comes right back up - IN THE SAND - NO PADDLES!

I really like my bike just the way it is right now - ALOT. The only thing that has really consistently beat me is a raptor 700 with big 3 plus port/polished head and stage 2 cams. And we were even on the big end, i was just already a few bikes back, but he wasn't going anywhere.

FWIW, I paid $28 for my Renthal.

 

[smo0oth1]

It'll be hard to keep the front down regardless, The stock gear should make it pull harder though. I wish I would have recorded the races we done here before the tear down. Launching with about 1/4 throttle and staying on two wheels till mid third is pretty exciting

So, you're going up there this weekend? Saturday?
