Just bought my son a 2010 Mini Dragon. Looks like a solid sled. A few scuffs on it here & there, but its a used sled, so that was expected.
Is there any MUST DO's??
Also, when we fired it up last night, it started fine, but the idel was rolling the whole time it was running. I was guessing old gas or a fouled plug. Any thought on this.
My plan is(I haven't even told my wife I bought it yet). I'm going to put it out in the shop & have my son go out there Christmas day & find it. He's gonna go f'ing crazy when he see's it.
REAR SHOCK KIT: I installed the rear shock kit (instructions are on
www.hardcoresledder.com, 120 section) It utilizes a Arctic Cat front ski shock. Shafts are 5/8" diameter steel, threaded for 5/16" coarse on the ends, spacers are 1/2" gas pipe, cut to fit. Works really well, reduces the bounce.
PARTS NEEDED
Start with a 77-78 Arctic Cat front ski shock, KIMPEX part # 08-114-14. approx $25.00 from mail order houses, Keep in mind that it's an oil shock, skinny shaft UP (fat body down) in order for it to work.
(1) 10.82" long 5/8" diameter steel shaft, threaded for 5/16" on the ends
(1) 5.28" long 5/8" diameter steel shaft, threaded for 5/16" on the ends
(3) 6" lengths of 1/2" gas pipe (from the hardware store) serves as some 5/8" I.D spacers to center that shock, or you can use those 5/8" locking collars with a set screw holding 'em in place.
(4) 5/16" coarse thread bolts with flat washers and lock washers
(4) 5/8" I.D. flat washers to fit over the shafts and go up against the shock rubber eye mounts
INSTALLATION
Drill (2) 5/16"DIAMETER holes in the tunnel (just forward of the upper rear bogie wheels) as per pix below, make sure you're into the steel back plates and just clear the upper rear bogie wheels
Drill (2) more 5/16" diameter holes in the aluminum rails per pix below (APPROX 1" FORWARD OF THE EXISTING 5/16" RAIL holes=drilling approx 14" ahead of the rear axle)
DO NOT CUT/MODIFY the suspension swing arm. As long as you follow the placement of the holes as outlined above, the shock will clear, it's a little close, but still 1/4" + clearance.
TIP: I located and attached the upper shaft and shock first, then temporarily located the lower holes to check clearance prior to drilling.
ROLLING IDLE: Rolling idle?? If the idle speed is "SURGING' the idle speed is too high. Lower it a bit and that will solve it.
SPEED CONTROL: You can adjust the speed by the 3 holes that the spring fits into, and / or by placing a small plastic wire tie (RED PLASTIC WIRE TIE in the photo posted below) to hold the spring in the CLOSED position.
OWNER'S MANUAL: The attachment listed below is the official 2008 POLARIS Owner's Manual, in case you didn't get one with the sled.
Santa brought a 2008 PINK 120 DRAGON to my daughter on Christmas Day 2007. I hope your son is excited as my 3 1/2 year old daughter was with her 120.
