To help with the hard rear suspension, it appears softer front springs would fit, I did order me coupple from dealer already but didn't get them yet.
Will le tyou know if it works.

 

The Polaris ATV Team Tips bulletin #A-06-06-04 lists all the parts changes for recalibrating the carb for a machine built after 3/7/06, quads built before this date have different parts/settings.

 

Vlastic:

You are saying softer front springs. Do you mean the stock front springs will fit on the rear? If you do, that is very interesting because I came to the same conclusion and also ordered new springs. They will be here on Wednesday. I hope they fit and that they are not too soft. On saturday, I weighed the left front wheel and then the left back wheel to see how much of a weight different there was between the two. I concluded that there was only about 5 pounds difference. If that is accurate, then I don't think the front springs will be too soft is used in the rear.

Let me know how it works out for you.

I just got a call from the dealer who I ordered the springs from and they had some good news. As she was calling to order them, the rep told her that they have had so many requests for softer springs that they have a set in the works. They did not have any more information than that. So I don't know when they will be available or the price. But it is good news that supposedly something is being developed.

FYI: The dealership also gave me the spring rate numbers of the rear and front springs. The rears are 140# and the fronts are 60#. So the fronts may have indeed been too soft for the rear.

 

Of course it would have been great if they had done their homework prior to releasing it so we wouldn't have to buy them and install them ourselves. Nice work Polaris, same goes for the carb jetting issue. One test run up a hill at 3000' would have told them they were way off on jetting.

 

Got it........the wife has had jetting issues with hers also, 10 to 15 MPH and that was it and yes the IDIOTS you call to ask for help don't know anyting. They couldn't even tell me if fixing it was under warranty or not....(Sir, you'll have to contact your dealer for that information) If I have to contact my dealer why in the F.... am I talking to you, and what is your job again....to tell me to call the dealer?! Thanks for the service.

HERE'S THE FIX...........
If your dealer won't replace the jets and wants to drill holes, keep in mind the jets are under 10 bucks and the labor should only be about 30 bucks or so I was told. I'd rather spend the cash than have 6 holes in my airbox.

Carb Pre 3/7/06--------------------------- Carb Post 3/7/06 (The right one)
Main jet 147.5----------------------------------- Main jet 140
Pilot jet 42.5--------------------------------------Pilot jet 45
Jet needle 4HB42-5-------------------------------Jet needle 4HC57-3
Neddle jet 04-m-----------------------------------Needle jet 05-m

Post 3/7/06 Altitude--------------------Below 40 degrees F ---------------Above 40 degrees F
0-6000 feet ------------------------------------145-----------------------------------140
6000-1200 feet------------------------------- 140------------------------------------135 or 6 1/2 inch holes in top of airbox....(stupid)

According to Polaris the dealer can either replace the jets or (stupid) drill 6 1/2 inch holes in the top of the airbox and you can self adjust by removing the rubber plugs in those holes, again (stupid)

Again Polaris is asking them to place this info in their service manuals but not telling the little guys, or admitting to it and recalling or fixing it with "no questions asked".

 

I did test the front suspension springs at the back and the're way too soft, the bike just sat down even after I did try to set the adjustments at it's hardest. If front number is 60 soft and back 140 softness number, as one of you said, then number 100 would be my next bet - if I can find it.

 

Good News! Finally got the Hawkeye rejetted at 142.5. It now runs like a charm. Dealer indicated that Polaris was not paying them for this service and that they had to absorb the costs. Is it true or not? I do not care as it did not cost me anything. I am now happy with how it runs. Now we have to wait for the spring issue. We will see what Polaris will do with this one?

 

Hey. I was waiting for a helmet to come in before riding my Hawkeye so I had time to get it ready. We live at 5000 feet and can ride up to at least 7600 feet. I read about jetting and stuff. I went down 3 main jet sizes (I think to 135), got a K&N air filter, installed a TPI valve, and a Dial A Jet kit. It would sputter a bit going up hills if not on the right setting. With a Dial A Jet kit you can add more fuel (increase jet size) by turning a setting with a flathead screwdriver. It will climb up hills with 4X4 that I really did not want to go back down, way steep rocky and loose, while leaning clear over the handle bars. Yes, way beyond the 25% incline so they are not liable for my stupidity. This thing rocks, and almost acts like a bigger quad, except for the small tires (rim dings). The only problem that I've had is a broken sub frame in the rear, where the front of the A-Arms connect on both sides. I thought the wheel looked crooked and realized one side was cracked and the other was about to fall off. Just dropped it off for a warranty repair. They should have used a much thicker gauge of steel in this area. Before riding INSPECT the rear sub-frame for cracks where the A-Arms connect!! I bought Polaris as I like to buy American and hope they can fix this defect.

 

Hawkeye Truly 4x4 Independent Suspension!
Today I got the idea to disconect rear IRS torsion bar just to find out what effect would that have.
To my amazement it softened the whole bike suspension like a magic. It appears to me the "stiff" rear springs are correctly rated after all - provided all four wheels work truly independently.
Yes, the bike tilts little more left and right in turns now but nowhere it is bad. It actually makes me feel like the whole bike's suspension came alive for the first time as in complete opposite to the bike's body simply following the rear axle as do bikes with one solid rear axle - you know what I mean.
All four wheels will balance itself against each other in harmony.
Next I went to find out if the machine will tilt when riding 25 degrees hill sideways but it doesn't show any noticeable difference.
I went spining circles on the gravel flat, and again no roll over here either.
I went some 20 - 25 mph jumping humping and again I lost no control.
40 degrees straight up as ussual no worries.
5 hours later coming out of woods I loved it.
These are results for 200 pounds weight man with 1300 miles on this bike previously.
I didn't test it at higher speeds since I go mostly over forest trails, dry river bed boulders or sand at rather slower speeds given 300 engine size, but don't think I'm gona put that bar back on.
It's possible Polaris put that bar in mainly for liability reasons, in case idiots roll over and sue because it wasn't there. In any case, your own test drive is only two unscrewed nuts away and free of charge, that is if you are ready to take the "training wheels" off :-)
