Hey, i just bought an 05 M7 that is all stock with a 153" attack 20 track. I just bought some Cutler IT adjustable weights and was wondering if anybody knows or has seen any elevation charts for the M7. I need to know how much to load up the weights for each elevation. At home i am at about 1600 ft, but also need to know what weight to run for the hills, about 3,000-5000 ft. And should i get another primary spring? Any online charts you guys have seen? Any help is very much appreciated.

According to ac 3-6k is for 70g weights. Best idea is to just run it and make sure you are right around 8000rpm when climbing/wide open. If not, add subtract weight accordingly.

If i remember correctly there is a chart under the hood for springs.

Ok Thanks, how about the weights themselves, anybody have experience with Cutler IT's. How do i load them up with 10 grams if the body of the main weight isn't long enough to screw any more into them? And does anybody have advice on whether or not to toe load the weight? Thanks again, any help is appreciated.

If I remeber correctly its about 68.5 grams when you load them all the way up and have part of the inserts sticking out the top. Performance of the weight is pretty decent. Some have had problems with the set screws not wanting to come out.

At home i ride @ about 1600 ft, but would like the ability to ride in the in the wyoming bighorns, maybe around bear lodge or gillette, which i think is about 4500+ft; correct me if i'm off though.

Factory clutching a stock M7

6-9,000 -68 grams
9,000 & up -65 grams

If you are riding around 8 or 9k I would try 66 grams maybe?
