Default Drivetrain problem, at low speed, with some ideas

Sorry if this has already been addressed on the board I'm to the forum, and could not find my problem.

03' Raptor. With the rear off the ground idleing in first gear, it seems like soemthing is binding up. It is very difficult to explain, but every so often like every 15 - 20 seconds it's like the rear axle wants to stop.

I have checked the chain tension, it's ok not to tight/loose. The adjustment screws are a little off the brake side one has to be backed pretty far out to get the rear end to come in to alignment, and it is still slightly off.

The quad has never had any kind of real serious damage however was put up on it's side (left) and had the handle bars replaced, and rear 6-pack rack. both bent.

Any Ideas? Keepin mind I'm a computer geek not extremly mechnical, if it electric I'm golden, if it's mechnical I suck! So I may not know all the proper terms for the parts!

Thanks inadvance.

Sounds like the carrier bearings could be going bad. Jack up the rear end and spin it to see if you can tell anything.

Default Thanks for the quick ideas

I tried it, I can not get it to duplicate with it in neutral, spinning the wheels either around the same peed as idle, or faster. It's SMOOOOOTH. But in 1st 2nd or 3rd WITHOUT using the throtle it does it, after thrid when the drivetrain is moving faster it does not. Also if I use throtle in first it does not do it.

Again thanks for any ideas

I noticed if I have mine jacked up in the air and let it run in 2nd or higher gear, idle only, it seems that it will build up a little slack in the drive train causing it to turn the wheels erractically. When I would hit the gas it smoooths right out. This happens on all of my freinds rides too. I dont think its anything to worry about. Just double check all you bearings and make sure your chain is adjusted properly though.

It would be interessting to see if other people have seen this too! Your discription matches my problem perfectly, except mine does it in first as well. Thanks for the info

Wow I feel real welcome in the forum. Thanks for the info. It does not really tell me why it does it, but at least it makes me feel better that something is not wrong with my ride in particular.

If I had to guess...imagine everything that has some kind of backlash, the transmission gears, countershaft sprocket to chain, chain to the rear sprocket, and rear sprocket hub to axle. Then, think of every one of those "loose" points having backlash at the same time.
That's the best explaination I can think of. If any one else has a better one,...

i would buy that WYORIDER. like driving an old truck that has a manual transmission.

im sure you guys have done that.
put it in first and idle down the road. it does the same thing as your quad.

Nice my 03' raptor similar to an old truck!!! Yeah I think I see what you mean. I never checked to see if it did it with the factory front sprocket, but like I said if no one else is having problems, I feel better.

lol, i did not mean to compare your 03 rappy to an old truck,

i just meant, what i was trying to explain was driveline lash.


this will bake your noodle. next time your on pavement, shift up 2 gears higher than you would normally ride, and GAS IT. the damn quad has so much torque that it will not bog down the engine, instead, it will shake the tires.
when i first seen that i thought something was wrong. But after talking with other raptor owners, its perfectly normal because the engine has so much torque.
i have NEVER been on a quad that had so much torque it would not bog, but instead it would shake the tires.

Nothing to worry about. Mine does the same thing. 1st, 2nd. Itís the chain. The chain when you feel is has some friction and is quite tight where the joints are. Just try it yourself. Pull the chain up and down and youíll see it sticks either up or down depending how you pull it. It also means your chain is in a good condition. When it stops having friction, you need to replace the chain. When you run it off the ground this friction sometimes causes the chain to stick a little and it will sound like something is catching. It only happens when you run it off the ground.
