    Quad Jerks

    When im riding in any gear and then i give it no gas and roll and then when u get back on the throttle it will jerk and jump when u first give it gas. Its not smooth at all. it only jumps when u go from no throttle to giving it throtle and its annoying. what could it be?

    Thanks

    It could be that you have alot of power in your quad.

    I don't really understand what you are asking.

    my 300ex does the same thing. I think you are talking about the chain stretching and getting really tight when it is loose. I can feel and hear my quad snap forward when hitting the gas from a standstill/slow roll. I am almost positive it is the chain -- and yes it is adjusted correctly. Maybe it is time for a new chain.

    i have a 300 ex and when i ajusted the chain i have a 180-200lbs person on the quad then make sure it has 2 " of movment. Only becasue if you ajust the chain then sit on it you wil see the chain get so tight it looks like it want to explode. Try this!

    well my quad is totally stock. has stock jettin and the chain is at the adjustment it came with and seems to be right. It does it warm or cold.

    Its hard to explain whats happening but i dont know any other way to say it. Its just when u first get on the throttle from no throttle the quad will all of a sudden jump instead of the power coming on smooth. I just hope its normal

    too loose!!

    what will happen if your chain is set too loose! mine is set to 1 3/4" with me on the bike. if i set it like in the manual once i get on the bike the chain makes a binding sound like it is going to snap. witch must be hard on the bearing in the tranny
