The factory primary is a yellow/green (mine was TI) it is a good choice. Make sure it's not broke first, that happens a lot. Factory weights for altitude were 69g on my '05 and they seem to be a good choice too but 67 may be better for you. A track upgrade from the A20 usually requires change to a straight 51 or 49* helix in the secondary to maintain backshift. Factory spring in the secondary is red/white and I have had no issue with it.

Is this sled new to you? What year?

The 035 belt works better and lasts longer than the 020 but is more $$$

Didn't know there were still any A20's still kicking. I pitched mine after one ride when the sled was brand new.

I used one 020 belt last season(500 miles last year) and I only changed it cause a new one was $55.

haha ya its a useless track , but its like new , so i flipped it around , and i will ride it for the rest of the winter like that . although if i keep the sled for any amount of time ,, a new track would be a good thing for it ,

Not saying the 020 is junk just that many people, myself included, have found a slight performance gain with the 035. Also the 035 is a little harder so wears better.
