Will possibly be buying fuel programmer to try and correct stalling issue on 2007 Grizzly 700. I was wondering if there was one particular brand or model of programmer that had good ratings from a lot of people. Also was looking for one that was pug and play....or maybe they are all that way.

Also, does anyone know if sock on fuel pump is replaceable? Has anyone had problems with fuel sock getting clogged with debris of breakdown of ethanol clogging sock. I believe these socks (filters) are made of several layers of filter like fabric.

lastly, I've seen many posts about setting idle and tps setting through pod but recently had dealer tell me that he didn't think you could make any adjustments from pod on this year of ATV. Appreciate anyones knowledge on these questions.

I have an 08 and the stalling issue was helped greatly from the dynateck PC3. Unfortunatly the pc3 quit on me (was 6 years old) odly enough havent noticed the stalling issue with it since go figure.

The stock fuel pump is replaceable i did mine in about 5 minutes. (i made a cut on one side of plastic under the seat support and bent it over so i had easy access.)

the pod mod on my 08 was possible but i never do recall if it actually helped much or not. Honestly i think what made mine go away more than anything was upping my compression ratio.(obviously not a simple thing to do)

Before assuming you have a fuel related problem causing a stalling issue, I would first inspect valve clearances. This is a maintenance item that should be completed every so often anyway.
Once valves are verified in correct clearances, then look into the fuel programmers.
EHS Fuel Programmers are very well liked around here....and he is a site sponsor as well. Makes great products and knows the Grizzly engine very well.

Surprised to see your thread having gone unnoticed for over a week, that usually doesn't happen unless no one knows how to respond. Chances are a lot were busy and your thread slipped by, I know I've had to travel for work the last few weeks.

Changing the fuel filter would be good maintenance but definitely follow dezz's information concerning the valves. The thought of valve adjustment get mentioned a lot when there are stalling issues and takes care of a good amount of those issues. Here are some good instructions to follow if you do it yourself, you will need a few tools to do it, mainly feeler gauges. But you'll also need a large metric hex key, I forget at the moment which size it is but I believe it is bigger than the largest 10mm that comes standard in many sets.

The '07 700 does have the availability of adjusting fueling via the POD but chances are, as dezz points out, it is your valves. But, it doesn't take long to check the POD to see if it is set to something other than default. I've used these instructions in the past to check and see if the used '07 700 I bought had the POD adjusted - Grizzly - Pod Mod - MudInMyBlood Forums

Thanks for the advice. I will check valve clearances. I didn't mention it but stalling is intermittent. Wouldn't an out of adjustment valve be more of a regular thing....in terms of stalling....as opposed to being intermittent? Appreciate advice in advance.

On my 08 the intermittent stalling was fixed with a HMF optimizer which is plug and play but I keep my valves adjusted so I knew that wasn't my problem.
