There is a 03 700 sks for sale near me. It has 10,000 miles and never been rebuilt. I was wondering what I should expect? How long can it go? It has the stainless valve upgrade.
My 05 went 13,000 before it needed attention.
I think 10,000 is the point were you tear it down and do a rebuild. That way you know what you got going on in there.
at 10k, I'd do a piston swap for sure, just for peace of mind. If bone stock, the 03 SKS did not have the hottest ignition or the sharpest carb setup, which both should help it last longer due to less stress
Thanks guys, My buddy just picked up an 03 600rmk 136. First thing I did was pull the valves and check with a magnet. I am glad he will not have to spend the $300 on new valves like I did!!!!
Thanks :bc:..yammie is the 4stroke god if anyone can get it done, its them. I would personally love a 4stroke, but 30-50% of my riding is off trail,soooo no 4 for me yet lol
I would think at 10k miles you would want to give the chassis a good going over... things like boggie wheel bearings, heim joints, spindle bushings, etc.
Motor wise, pistons for sure. I'd also check the carb sliders closely to make sure they haven't worn in the bore.
That's why they got the viper chassis from arctic cat. Check out the comparison test on you tube vs the RMK and summit. It was visibly biased (look how much snow they left on the rmk for the "wet weight") but the numbers look good, especially in higher altitudes.
Ive ridden with and xf800 (same chassis with a 141x1.375" cobra and AC 800 motor) and that sled is good in the deep stuff, not my RMK, but good. I also rode with the viper xtx on the same ride (same sled but yamaha 1000) and it's not quite as good, but still respectable compared to any other 4 stroke I have witnessed. I am sure the MTX would be a great off trail sled!
