Engine braking

Just purchased 06 650LE , first ATV ever, after my son bought a 500 auto last fall, and of course after riding his I just had to have one of my own. Was very impressed with the 500's ability to crawl some very steep and rough stuff, but thought I needed a little more 'hit' when I thumbed the throttle. Chose the AC650V2 after looking at specs of all major players in the ATV market. Am not disappointed with the performance, either, but immediatly upon off loading my new work/play toy from my pickup, I found an annoying problem, or what seems to me a problem. When I started down my drive, arather mild slope compared to where we really ride, the bike began free-wheeling, the engine braking, then free=wheeling, while simultaneously making a 'clack-a-clack-clack' noise. While I am not a professional mechanic, the shade tree mechanic in me says this is not a healthy sound. It really got hairy when I started down the nearly verticle trail leading down to the bottom of my property, requiring continual very firm pressure on the brake lever to keep from a total runaway with the Clacking sound in accompaniment til I got to the bottom of the trail.

On the other hand my son had only to touch his brakes occasionally, and not a single unhealthy mechanical noise. What gives? I realize his is a Suzuki single with a different tranny arrange, but it is hard to think that my bike is acting normally for a Kawi setup. Any other 650v2 riders out there have this problem?

I went on to ride 64 miles of trail, and the problem seemed to diminish as the miles accumulated, but never totally resolved. Rode again a few days later, same problem. Also noticed I can not climb as radically on the 650v2 as on the 500. Maybe I should have gotten a 500, as I have been reading a lot of negative reviews by 650v2 owners (after I made this purchase, of course). On the other hand once I get off the rocks and steeps, mine is more fun than the 500, and I can ford an inch deeper with out having to lift feet to keep them dry.

Anyway, anybody got any wisdom about the engine braking situation? Different tires might solve the climbing issue. Thanks for any helpful input.

P.S. New to this site, too, as well as new to ATVing. Don't have any pics, but mine is the Tony Stewart Edition. Bright! Hard to lose it in the woods. Thank God for the winch, used it several times already to get out of fixes on steep slopes.
By the way I'm 57 and I'm having fun, though I told my wife I needed ATV for 'work' LOL. Don't get along with computers, and haven't figured out how to use the 'clickables.

welcome call :site:

Hi, I can't say I have ever had mine freewheel when going down a hill. I normally have to give it some gas. The V2 setup is a little noiser then most IMO. It's possible that the actuator(I think) is screwed up. Are the clutch springs stock? That will make a difference in the engine braking too. Also, make sure the belt is on the tight side of deflection. That is the best thing you can do for the v2.

Anyway here is a free bump. Someone should be able to fill you in better.
As for the Clickables, just click on them and you will see some added text in the text area. :chug: :lol: :moon: :D :thumbsup:

Welcome to Arctic Chat! :site: Never had a problem w/ my 650V's engine brakes or heard the sound you're describing? I dunno Maybe a return trip to the dealer is in order. :( Good luck and keep us informed! :thumbsup:

problem is when you are going real slow correct? the engine brake dissenguages at a certian speed (3 mph roughly) and if you are going from 1-6 mph back and forth then it will do what it sounds like it is. kicking on then off while jerking the machine some. this is somewhat normal imo. some people i believe unplug there eb then the clutches are you engine brake only. what i did notice is when after brake in i took my belt cover off to check defelection (which was loose) and when i took a shim out to tighten the belt the eb worked alot better and down to roughly 2mph, also gained a tad lower start gear due to it riding up on the secondary clutch higher.

play with your air pressures but you will come to the conclusion that the stock tires preaty much suck as many of us have replace. i only run mine in the winter for plowing.

lots of good info on this site keep looking around you will find a answer to just about anything! by the way WELCOME!

I also have the TS editon V2. I have A Dalton high altitude clutch and a VDI chip. I run 28'' outlaws but wish I got the 29.5''. I put the matching hand guards on too! I also got the matching TS helmet. Anyways First thing first.. check your heat shield on your exuast... mine and most all 650 V2 are touching the plastic. I got back from hunting in September and I had a melted little hole in my rear fender. I took it to the dealer and they bent it back outta the way and gave me a new one on warranty. I also have gone down some steep hills and have never experianced the crackling engine breaking sounds you have. I do how ever have a grosse sound when I have my locker on sometimes when its working really hard. I don't like the sound, but I guess it hasn't messed anything up yet. I have also took off my muffler and then zip disked the end off and drilled 6 - 5/8'' holes all around through the 2 plates and then welded it back up. I would say it added a few horses.. you can notice it anyway and it doesn't even make it louder! So all in all you get that checked ou so you can enjoy your TS as much as I have!

I think Kevin nailed it with tightening your belt. They come a bit on the loose side (sometimes out of tolerance) direct from the factory. Go figure. At any rate, that will have an impact on your engine braking. Get that belt checked out.

With regards to the issues on a 650 V2 that you've read, you're in good shape if you ensure the belt is good and tight.

I might recommend checking out a thread I posted (not patting myself on the back here at all....seriously). Might help you with the V2 right out of the gate.

:site: Seven replies to a query posted at 3:eek:o AM this morning!?! Awesome. Thanks Sanny, Whiteone, Green Goblin, ZH1, Kevin, Dezfan, and Molsondrinker.

Great pics of your ATV/submarines, Whiteone, and beautiful scenery. Thanks. Read and re-read your thread on 650v2 need to fix, Sanny651 --informative and very well done. Thanks to you, too.

I had suspected poor belt tensioning might be a culprit in the problem. I will be taking ATV in for 100mile service soon and hopefully the problem will be resolved.
Dealer is about a hundred miles away, so wont be running down there on a frequent basis, know what I mean? Could have bought one closer to home, but for 1300 dollars savings I can drive a hundred miles now and then. I called the dealer and talked to a mechanic and he said problem is abnormal and to bring it in for service. Talked to local A/C mechanic and he said all 650v2's act this way :oops:

Anyway, encouraging that none of you are having this problem. I would be very :angry: :angry: if I thought I was going to be hung with something that doesn't meet my expectations. Want to stay "Smilinjack"

You'll love your V2 smilinjack. I adjusted the belt myself, and I'm no ASE certified mechanic. :) Plenty easy enough to do, and it'll save you money. However, in this case it might be good to bring it in and have them take a look at it after the breakin period. Give it a good once over.

Well you beat me to it, Iwas going to recomend reading your post. I think that every new 650 owner should. :beer_cheers:

Doing the belt isn't to bad. Do it once and it will no problem the second time. Lots of info on here and nyroc's site.
Also, keep in mind that you don't need to get it serviced at the place you bought it. Needs to be a Cat dealer. I take mine between 2 places when needed. One where I bought it and one a little closer to home. Some prefer to deal with the guy that sold it to them though. Im' not picky, whoever can get the job done right is what matters to me.

I'm curious, when you say "free-wheel", how fast will it coast down a fairly steep hill? My engine brake actuator died at about 500 miles and I could get the bike to coast up to 20 miles an hour down a steep hill (a pretty good indication that the engine break wasn't working!). The actuator was replaced by my dealer under warrenty.
The other thing to check is if the engine breaking is different when you are in high vs low. In low going down a steep grade, the actuator is constantly going on and off, and it keeps you going real slow. In high, at least on my bike, the actuator doesn't seem to alternate on and off, but allows the bike to go slightly faster. It's much quieter in high.
But if it's actually freewheeling down a hill, at least as I understand freewheeling, your engine breaking can't be functioning properly, even with a loose belt.
Definately have the dealer check it.

I know what he is talking about, the 500 makes the same sound if I slam the brakes on real hard on a hill or anywere enough to slow you down pretty fast. Someone on here said it was a sound to keep the gears from binding up inside the tranny so u dont ruin them but if it is reeal loud it dosent sound healthy. Also mine slips outta gear if a lock the brakes i just need to blip the throttel to get it back goign again but i though i would throw it out there aswell.

:super_happy: just got back from a night ride, and yes, kevin the problem seems to be most evident at slooow speeds going down slopes that might qualify as extreme (certainly well beyond the 25 degree slopes warning in the owners manual) :D The engine braking seems to work fine at higher speeds on slopes less than 45 degrees. However my first 150 yards of trail down to the national forest trails is as much as maybe 70 degrees in places and I have to ride the hand brake and foot brake hard to keep speed down enogh to dodge trees and rocks.

As for gtdoctor's question, the above should let you know... I don't have the luxury of letting it go to see how fast it will free wheel. Those trees and rocks are big, solid, well rooted, and the terrain is unfriendly too. I do know that it doesn't free wheel on normal sloping logging roads, but I didn't buy it to ride logging roads :D

Still great fun, challenging, adrenaline pumping, coming back up that slope in the dark, front wheels off the ground several times, leaning over the handle bars as far as I could, thought I might flip it twice, kept it on the trail and out of the trees, pulled into my driveway with a big :D . I better do something about those tires soon.... later, y'all. :trail: :D jackflash

Hey slim.
I dont think it should free wheel at all. Take it to the dealer while it is still under warenty. I think there is something wrong with your acuater or it is in the limp home mode. My 05 650 has great breaking. Even if it's 100 miles git it fixed asap.
good luck

Love the pics, my style of riding and looks like my backyard :thumbsup: It's a shame your in Alberta, it would be nice to join you on a ride.

Thanks GG! It is awesome riding there. We go every long weekend and we find new places every time! The guys I go with have been going to the same spot for 8 years and still find new areas to go! I recomend taking a week holiday and visiting the area. It is 46 km west of Rocky mountain house on Hwy 11. Exactly on the 46km mark turn right into a place called Jackfish and take that logging road about 15 km back! It's good because its not quite the mountains so you dont get the hard trails and rocks.... Just good Ol fashioned loon :turd: !! If you ever go maybe we'll meet up for some :beer_cheers: !

Is the clicking/clacking coming from the differential? I noticed mine doing the same thing going down hills. It will only make that noise in 2wd, right? If you keep it in 4wd it won't make the noise because the front end is engaged. If I know I'm going down a steep hill I make sure to put it in 4wd just so I don't have the clacking because it doesn't sound to good for the parts. If anyone knows what actually is bouncing around in 2wd when going down hills I sure would like to hear what it is.

take some pics of those slopes that looks interesting. :trail:

Hey, Crashnburn! Been out of pocket past few days, just got back to forum. My Cat Clacks in low range 4wd the most, not so much in 4HI, and haven't noticed it at all in 2wd, but then I'm not often in 2wd. The clacking seems to come from down in the pwertrain area. The last time I rode, last Thursday night, I tried to pay close attention to all the feels and sounds. Seems the longer I ride the less the thing lurches and clacks.. I tend to agree with the others comments that my belt just needs adjusted properly. Sure hope it's that simple a fix, anyway. Don't know much about all this stuff right now but I'm a quick learner (used to be anyway :D ).

Yeah, Whiteone, I told my wife I thought your pic were taken in the North or Northwest, judging from the flora and fauna. Beautiful. 4 wheeling is great, lets you see the country from a whole new perspective. :thumbsup:
