'10 IQR 600 high alt. clutching help

rheinss10 · Jan 30, 2012

My buddy is taking his stock '10 600 IQ racer on our trip to Cooke city and lookin for some help on which weight to go with. He runs 58g 10-58's here in MN. I was guessing that he should drop 6-8 grams but want to look for a little help first. Any help would be awesome

I run my 09 at 6 - 10000' with 10al weights (53) 140/330 primaryspring, black silver secondary with the 70 side of the helix...20/44 gearing and timing sensor on E with pump gas. Spins 8300 until you get way high in a climb it just won't pull the weight unless I take time to re jet... 370 mains...40 piolt...I love it! Oh I also have a 136 on it too...but motor is all stock...hope this helps

Sled is a blast with a 136!! You'll love it. Stock iqr skid with ice age rails stock shocks. Actually does quite good in powder. The wetter the better the real dry fluffy dream pow it will struggle a bit and you may have to track poach a bit but will surprise you in its powder performance. Plus you can still beat on it and it will hold up!! Oh yeah vanamburg tunnel extension

Your running 370 jets at 6-10K? I run 390s here in the flatlands. I was told you could go down to 320s or so? I will be going to togwotee or Centennial in about a month. Kinda looking for some advice as well.

I have a 2011 and ride at Toqwotee. I ran 10-64 weights and the sled maintained its rpm's. I believe I am running a speedwerx primary spring and I wanna say its the almond purple or almond red. hope this helps

I will be in togwotee next weekend thru the first, I run 390's with the needle on the second clip. I never had a bog or fouled plugs. This year I will be running an atacc.

Huh? 64s at 8000+ft on a 600?? No way. I ran 60's and 62's on my 800 Monoblock 8000 ft last year. I guess you could run a very unusual primary spring. But 64's are higher than most run at sea-level on a 600.
