Anyone put anti ratchets on a new IQ without a set back?

The first of the M-series cats had poor geometry that tightended up the track when it worked thru the travel and caused all kinds of problems that was the big factory push to extros and the one that gave the extros and stabbing a bad rap.

Polaris used Extros on thier race sleds last year and this, Ski-Doo and Yami now (both have very large R&D budgets as does Cat)...

Again, this is IMO....

I don't think either of you are off base with what you are saying. It is not practical to expect performance out of an extremely loose track!

I have designed packaging machinery for quite a few years now and could tell you that nothing in the "mechanical world" was made to flop around a drive mechanism and last very long. The best thing an extro can give you is some... some insurance, when tensioned properly!
