Rear Shock Poll

[sledheadgeorge]

This is what happened to my sons GT.
500 miles- shock blown. Replaced under warrenty. Dealer said it needs heavier rate spring. Jr. is only 190lbs dressed. So I argue........Why does he need the heavier rate spring? Anyways, installed heavier rate spring (which had to be paid for)and now electronic feature works properlly (you don't have to ride it full dampning so it doesn't bottom out all the time, and it can accually be adjusted) but #1. there is hardlly no weight transfer even with W/T adjustment set to almost max. #2 the new shock only goes 2000miles and is blown again.
I think the valving in this shock is all wrong and so is heavier rate spring. The valving should be changed and the stock shock spring should work fine.
I think Yami spec'd the shock from Olins wrong and does not want to admit it.
I think its BS to have to pay for some Engineers screw up of specs.
Along with the HANDWARMERS THAT DO NOT WORK PROPERLLY I was going to snowcheck a new sled this year and desided not to because of these issues. I HAVE YET TO RECEIVE ANY NOTIFICATION FROM YAMAHA ABOUT ANY SOLUTION TO THESE PROBLEMS. I don't mind spending more for a quality product, but if I have to come good for any updates that should have been worked out before I purchased the machine........ .......I take a very dim view of that. THE WORST IS NOT GETTING A DIRECT ANSWER. YES or NO This is very frustrating.........................

Something is not right with the Ohlins EC Rear shock in the GT's. I was talking to a guy who rebuilds ohlins and he told me "In His Opinion" there was an internal wear issue with the EC shock. From the way he described it I took it to mean the shock looked like it had more miles on it Internally than it actually did. I said "I thought that was there (ohlins) claim to fame. Not have to rebuild them as often as regular shocks?" He told me that was never an issue with the front ohlin shocks.
He also said he has revalved some stock mono's and they looked pretty good internally.

Both of our sleds attak and rtx have standard shock package and both now still have stock spring,now as some of you know,i started on the attak and upgraded to the big boy spring,than swapped the skid out to matt,so now i have his short track and stock shock less big boy spring,and his shock remains in stock c clip setting,and it does bottom but rides very nice,now my boys stock rtx has stock spring on 2 nd c clip setting and is almost perfect,all but needing some revalve attention,at least new heavier oil and gas,and same for mine,sweet set up now i really love this shorti of mine,all it needs is another pair of floats and simmonds skis...

I have stock Apex. I have not had leaking problems but have notice the shock and spring are fading after about 2000 miles. I plan to go to heavy spring next year, but am concerned this might be harsh in terms of rebound. Should help the fading and bottoming though.

If it is only now after 2000 miles that it fades,than its time to change oil and regas,and i would have them add a heavier weight oil,and if you are under 200# get rid of the big boy spring and set the c clip on 2 and adjust up your cam adjuster and set your transfer rod to near min.. happy trails.

Thats fine for a stock shock. But we are talking about the Ohlins electric rear shock on the GT

I think the poll gives both shocks as an example of which ones are more prone to failures,and our sogi shocks are ready for a rebuild as well,now the gt with the ohlins shock that rides with us,broke his shock and it was replaced by yamaha,but is still at 06 yamaha specs,and he has the 5.5 spring and he only weighs 150# wet.

I think the valving in this shock is all wrong and so is heavier rate spring. The valving should be changed and the stock shock spring should work fine.

For aggressive trail riding I am quite sure that you will need both the stiffer spring and more damping.
Please keep in mind that the european GT is delivered with a 46% stiffer spring and almost 100% more damping than the american GT.
I have tried variations of this shock package in three different sleds (-05 RX-1, -06 RX-1 and -06 RX Warrior).
With the european setup all of them performed very well on rough trails.

More dampning I agree, But we do not have the same trail conditions that you have in Europe here in Canada.

According to my experience, the stiffer spring is necessary if you want to stop bottoming out in g-outs (the load in a g-out is acting for a long time - sometimes too long time for any damping to stop the shock from bottoming out).
Also according to my experience, the ride does not get noticeably harsher from a stiffer spring. Though, if you use a too soft spring and just crank up the damping you will end up with a very harsh ride.

I have an ER and was thinking of putting the Ohlins electric shock on. Would a re-valve cure the premature wear mentioned above. I currently have my stock ER shock at the shop getting a re-valve for more bottom control.

I have 450 miles on my sled and my shock blew out about 150 miles.I just got a dealer to replace it undr warr.They keep my heavy spring though.

Yes, that re-valve will definetly help. I truley believe that the 06EC's only have a valving issues and it's not there shock itself and I bet if you wait the 07's EC will have much better valving and we will be able to update our's to match the 07 valving.

Most of the guys I talk to are very happy with the EC rear shocks.
Some of them have a small oil leak in very cold temperature but they have got it fix by a Yamaha or an Öhlins service centre.

The first ride on my 06 apex was nothing less than bottoming out. I sent the shock to Pioneer Performance and requested a heavier spring and the European dampening option. Flawless; except then the wire broke to the shock (I did install the wire as it was done by the factory). I only realized this since the control didn't work on the dash. After fixing the connection, the EC dash control only works for the first 2 seconds when the snowmobile is first turned on. The MODE BUTTON does not toggle between the hand warmer and the EC Control. ---DOES ANYONE KNOW ANYTHING ABOUT THIS???????????----The circuit board most likely shorted when the connection grounded to the frame(since the 10 amp fuse didn't blow like it should have)

Anyway, the grease fittings are welded so they leak and 1 has broken off. The paint is coming off and the suspension is rusting. A M-10 will be the solution for this and the old suspension will be thrown thru the window of my local yamaha dealer.(just kidding)

The front end squeeks loud enough to get though my helment to drive me crazy. The steering adds a 1/2 inch of play to if every time I sit on it. Pretty soon I'll have to spin the handlebars a complete turn before the ski's will move.

What do you expect for 10 grand plus!

A x-package ski- doo would have been a much better decision!!!!
