High Idle Help!

Alright I'm new to the forum, and I have huge problem with my 2004 Grizzly 660.


The problem I'm having with my Grizzly, is a very high idle.

This came about after having starting problems. First, I replaced the starter relay, and that did nothing. So, my father messed with the carb to get any water out it.

Now,

High Idle
The auto tranny won't shift unless I choke it.

I have no idea what the problem is?
I would rather know what needs to be done before I take it to a shop and get raped for the fix.


Please Help...Any suggestions would be appreciated!!

Thanks

It sounds similar to a problem I had with a Griz 600. Even after a carb cleaning I had a "random" occurring high idle. It ended up being the enrichment plunger (choke) and cable. After replacing both I had no problems.

Perhaps if the setup is similar on your ride you could push/pull on the choke cable while it's doing the high idle thing. If RPM changes it'd be a good clue that's the problem.

ok first of all you have an idle set screw if you turn it counterclockwise does it idle down to where you need it second thing you need to check is did the throtle cable get moved your idle is set by the length of the cable if you moved it to where it is in a bind meaning pulled tight your idle will increase it may look ok at the handle bars but be pulled tight under the tank.
