I knew it made a big difference on my bruin 350..never thought about trying it out on the grizzly.
Dude do you have pictures or videos and mor info thanksThis is probably the most obvious thing to everyone but me, but since I have owned several Yamaha Grizzly ATVs over the years, and just discovered this now, I thought I would post it. The Yamaha Grizzly 700 is governed by the throttle stop screw on the handlebars. I read about the Can Am 800s being limited by the throttle stop screw, so I removed the throttle stop screw on our Can Am. Removing that throttle stop screw made a huge improvement in top end power, with at least a 25% increase in top end power. I liked the results so much that I decided to adjust the throttle stop screw on our Grizzly 700. I backed it out almost 1/4", and retightened the lock nut, and then took it for a ride. It didn't make as much difference as it did with the Can Am, but there is a very definite increase in top end power. I would estimate that the increase in power with a Yamaha Grizzly is at least equal to the gain that is typically acheived with an aftermarket exhaust system. And the best part is that it is free.
DesertFox, I can't provide pictures for the Grizz, but when I do this with my Outlander, I will take pics or video and post it for ya. The over-all concept should be the same. In the meantime, you may want to look in your users manual to see if it mentions it in there. If memory serves me correctly, this was also an option on my 07 660. (I won't swear to it though.)Dude do you have pictures or videos and mor info thanks
That was my take on the situation. I figured you didn't want to leave a hole in that box to let moisture/dirt in, but I also figured you wouldn't have left any restrictions in place.Battlegun,
I completely removed the throttle screw on my Can Am as well. But the Yamaha throttle housing will get full of dirt if you don't have the throttle stop screw in there. You just don't want it threaded in far enough to actually limit application of full throttle.
Not real sure formguy, but it wouldn't hurt to take a peek. I feel that this is something that is used across the board, but that is just a hunch. Look at the photo posted by 3TV. My screw looked identical, but without the throttle body. Let us know what you find out. This is one of those ever-so precious free mods!I wonder if the rincon has that problem.
