Is there an adjustmetn on the engine braking for the 360? My engine braking seems to be letting loose quicker then when it was new, my belt deflection is TIGHT .73 inches, & squels at idle, so it's not a belt problem. Maybe I'm just confused, but it sure dont seem to work as well as it once did.

Yes there is a adjustment on the rod from shifter, I think there is a write up on Master Nyrocs site.
mine kicks out witha rattle like its trying to grab. engaging and disengaging at a fast rate. if i hold the shifter ahead when in low range it stops and stays engaged. It never does it in high range.
Next time i have the cover off i will adjust it.
Check past treads on this i believe it is a common ailment.

 

I think Uinithas is talking about the engine braking system itself, not the transmission linkage adjustment. The engine braking is self-adjusting, it resets itself every time the key is turned on and off. If your belt gets a little glazed on the sides it may cause some belt slippage and loss of engine braking. I buff my belt with coarse emory cloth any time I have the cover off.

 

Hello. I am new to the forum and I joined to talk to some people who own a Prairie 650 four times four. I going to buy one eventually no matter what but, what I really want to know is how the Prairie does on sand dunes. My wife and I ride our Raptor and 250EX on the Oregon coastal sand dunes frequently and there some very steep dunes to pick from there. Completly absent from any ATV magazine is a 4x4 shootout on sand dunes. I know the prairie is light and very agile, but do you think it is enough to keep it up on top of the sand? If you have not had yours on the sand, can you refer me to a Prairie owner who has?

Thanks, Craig

 

If you going where you want to go on a 250EX, the P650 will go anywhere the 250EX will, only a lot faster!

 

So adjusting the shift linkage is not going to make the engine braking stronger right? I will try the coarse emery cloth, & see if that helps out. Is that about all that can be done?

 

There has been the odd engine braking servo failure. I'd take it back to the shop if it still doesn't work after roughing up the belt.

I dont believe its your belt at that spec. but low range gives a lot better engine breaking then high range.
engine breaking will dissengage at real slow speed, i never checked to see how slow in low range, but i knew it has been necessary to use some throttle to get down some steep hills i have been on, olso i have been giving some throttle to get the breaking to engage and stay engaged to slow decent. i hardley ever check speedo i believe its instinct or using the force.

 

Hey stocker660,
Even with the stock tires, I have run with and outrun Scambler 500 H.O.'s with paddles at Glamis and the dunes at Waldron, Colo. It is not going to perform like an ATV designed and set up for dune running but you can go almost anywhere you got the ***** to ride it.

 

Thanks GeeBee. That is pretty much what I figured. I only asked because the Prairie 650 is one of the few flagship four wheel drives that I have not test rode yet. The ones I have (Rubicon, Rincon, Grizzly, and every 800 pound Polaris model) have been good in the dirt, but complete terds on the dunes. I not going to expect the Prairie to go everywhere where my Raptor goes on the dunes, but I have read somewhere that the Prairie actually makes about 10 horsepower more than the Yamaha Raptor. So it would make sense if you threw paddles on the back axle of the Prairie it should climb a pretty steep dune. My Wife's 250EX is pretty limited on the dunes even with six lug paddles. It did better after I installed a Big Gun full system, jet kit, and a K & N Filter. Our 250 EX is the camp workhorse / thrashing vehicle when we go to the dunes. When my wife is not looking, we usually grab it and see how big of a load of firewood it will pull back to camp while mainting a wheelie. Instead of putting the poor little 250EX through such abuse, I need to just buy a Prairie after I finish up college this year, 10-4!
