A taller gear ratio with a 23/49 isn't horrible but you have to have the clutching to pull it.

A 20 should fit with no issues with the stock chain. It should actually take some of the dog leg out.

How many miles are on the Primary? The primary and secondary springs are likely sacked out already and everything else could use a refresh, buttons, orings, rollers, spring cup and shieve bushing if you have over 1000 miles on it. I lost 400 rpm from last winter to this winter. After a few rides this winter I rebuilt the clutches, first ride I was already back down to clicker 2 from 6. All last season I maintained 3 after break in.

Suspension, for climbing, not a lot of preload on the ski shocks, about 2-3. Limiter in stock hole or suck it up one. Center shock back off all the preload then just 2-3 tuns of preload. Rear springs, if you have stock rears, set on 4 or 5 depending on riding weight. Heavy springs, 1 or 2.

my '12 completely stock gearing and clutching gets a full shift at WOT, and average 50mph while climbing in decent fresh up good pulls with excellent back shift. A 20T would likely get you a few more mph.

What are your peak RPM's while climbing? Make sure you don't go over the 7900 if everything else is stock. Except the can, but a can wouldn't get you a peak rpm change.

I only have 400 miles on the sled. Runs good but ever since the clutch and gears it doesn't perform the best.

It's the spi clutch kit in it.

Rooster built kit in mine 21 gear pulls awesome.

Why did you change it? What did the stock clutching not do that made you change to a kit like the SPI?

If you have all the stock components I would put them all back in. SPI offers lots of aftermarket items, one thing I never really see much of people using is their clutching.

The '12 stock clutching (which I believe is the same for '13 in the XM) has its shortcomings. Overall it is not a bad package. It tends to be a dog off the line, but these aren't drag sleds. The backshift is good and shifts out well.

Actually come t think of it, I think it is a 23.

My 2012 etec800 154 is a trenching pos I got a clutch kit in it and put at 23 top gear in it. It trenches like crazy and I only get 40 mph out of it climbing. Any suggestions. Thanks.

First off, spi clutch kit does not work, cut your losses go back to stock, or buy a roosterbuilt kit.
