Hey, can any of you guys tell me how the engine braking on the AC 650 performs. If in 4X4 going downhill, does it "drag" all 4 wheels? I heard the polarises will only drag the rear wheels when engine braking downhill.

 

Dear Insane Ape,

I have had my 650 for about a month now and I am pleased with the engine braking. It does not drag any of the wheels while going down hill. It free wheels a little bit more than my yamaha 650 but not much more. Hope this helps.

 

The engine braking is more than I want sometimes. Works as good as any shifter I have ever ridden.

 

Engine braking is great on this quad. When going down hill if your in 4x4 engine braking will be applied to all 4 tires. If in 2wd, only the rear wheels. In low range going down hill it crawls, on small hills it can almost stop.

 

My Cat 650 engine braking isn't as good as it was on my Prairie 650, I think the Belt is still too loose. I had the belt adjusted but I still can hear the belt squawk now & then, which is not a good sound to hear. I plan to reinstall the .8 shim along with the shim that is already in & then put in the EPI Black Spring, from what I have read on other post, this should cure my belt squawking & greatly improve my engine braking.

 

Mine works perfectly. Even in the mountains, I rarely have to touch the brakes when going down hill in low range. I did have to have my belt tightened a little after 70 or so miles, but 100 miles later, it still works perfectly with no slipping, chirps, or any negative behavior. I couldn't be happier with the machine.

 

Thanks for responding guys, it's just what I wanted to hear.....the AC 650 is still at the top of my list for my first 4X4. Just need to save a little more $$$!!!

 

I own a 2003 polaris 700 and a arctic cat 400 and have owned hondas and yamahas.
When going down steep hills my arctic cat and hondas-yamahas work alot better than the polaris rear wheel only ebs as a matter of fact i wrote polaris telling them i think there ebs is dangerous.The first time i rode my 700 we went down a rather steep trail I went down the trail trying every method i know to keep the machine under control but was in a dangerous slide all the way down to the bottom and was lucky i wasen't hurt. the other 2 machines that were with me a arctic cat and a honda went down the hill under control and they hardly had to hit there brakes[boy was i mad] . this was just after polaris sent me a letter saying if i dident attend there rider saftey coarse they would void my warranty. One of the reasons i buy 4wdrs is for the control going down hills you would think for 7.600.00 you would get more.

 

Don't get me wrong here.
I know the Cat 650 too has excellent engine braking, mine just isn't set up right yet for my liking. On my Prairie 650s I had the Kawasaki High Altitude Clutch kit installed & one of the shims removed. One of my buddies had the Black Spring & also one of the shims removed & both of our P650s had excellent engine braking with no-locking up of any of the wheels no matter how steep the down grade was.
I do have all 5 of the needed shims & when I get the time to do the belt adjustment, I will get the right combo of shim/shims & the Black spring to work correctly.
