2004 Sportsman 600 Radiator Tabs Broken

Came back from a 120Km ride and half way in noticed the 2 radiator mounting tabs at the top of the radiator were cracked and one was completely broken off. Limped home for 60Km after some zip ties and duct tape held things together.

Before I drop some money on another radiator, has anyone had this happen before?

Quad only has 850Km and I want to make sure this isn't something that will happen again.

What other years does 2001 plow mount work on

I have a Polaris Glacier plow and mount from a 2001 Sportsman 500. The mount will not fit on a 2004, the front mounting bolts are different than the 2001. What other years will it work on? I think up till 2003 but not sure on the older versions before 2001. If anyone knows can you please post what years are the same mount as the 2001. Thanks much

Need some more help with brakes

I posted another thread about a week ago but it has died so I thought I would try a new one. There's a fall festival this weekend that I would really like to ride in.

On my last ride, I lost all my brakes, as in the lever went to the handlebar and didnt stop. I got home and realized fluid was pumping from the upper reservoir to the foot brake reservoir and vice versa when I pumped either brake. I replaced all pads and my rear caliper, and it didnt help. Fluid is still pumping between the two reservoirs and I have no resistance at the levers. I agreed with the advice that I got here, in that the only place the fluid from the upper and lower systems meet is at the rear caliper. So I'm wondering if I could have gotten a bad caliper, or if a bad master cylinder could cause the same symptoms? I am removing the masters right now to try visually inspecting them but would love some advice on what could cause this. I have bled the brakes with a mighty vac, and even tried a zip tie on the foot brake overnight to get any air out. The brakes bleed fine, and they do grab when I squeeze the lever, just not enough to provide resistance at the lever. I would think that SOME resistance should be there if everything was working properly but I still had air in the system. I also hear a bubbly sound in the rear caliper when I push the foot brake. Its faint, but I hear something in there whether its air or just fluid moving.

Demand Drive Fluid Question

I had planned on changing the hub fluid tonight and riding tomorrow for the first time. Only problem is no one stocks this fluid locally. The one Polaris dealer does not sell it and only offers their services to change the fluid.
I have read that Amsoil ATF may be a equal replacement but am not 100% confident yet. My machine is a 1997 Sportsman 500 and the documentation I have read suggests only using part number 2871654 Premium Demand Drive Fluid. Can anyone offer suggestions about the Amsoil ATF for my vehicle please?

Sportsman SP 570 vs 850 high altitude

Hi all,
I am considering purchasing a sportsman ATV. I am new to ATV's. Have a 2006 Yamaha 450F dirt bike and 2013 RXR 900XP Walker Evans edition 2 seater.

I could try and sell RZR and look for 4 seater or buy a ATV for wife or I to ride with RZR.

Questions:

1. Is the SP suspension with dual A-Arm and more clearance that much better than standard Sportsman with McPherson strut? I am a bit spoiled by the plush suspension on the RZR so I want to get the best riding ATV.

2. I have the original XP 900 27x9x12 and 27x12x12 big horn tires on Polaris Black crusher wheels. Will those bolt up to a 570 or 850 Sportsman?

3. I ride at high altitude 6000 ft - 8000 ft mostly but sometimes 10000 ft. Is the 570 enough? Is the 850 based on the RZR XP900 engine?

4. I wouldn't mind buying a clean used model. I have a 78.8" long standard bed truck, I could possibly get tailgate closed if I buy or make wheel lifts to raise front of atv?

1000 vs 1000R

Am planning to purchase a Maverick Sport DPS in the next 6 months or so. Is it worth $1500 to get the 100HP 1000R or is the 75HP version enough for normal trail riding. Is the new flip up windshield durable and worth the $1000 price tag?? Thanks for all replies.
