2013 XTX new to me with 3000 miles on it.
Bone stock powertrain.
Unstudded oem ripsaw, groomed trail riding.
I went over the sled entirely when I bought it, clutches look good as far as components.
New slider buttons and a new oem 8DN belt installed now.
There is a pink spring and stock helix in the secondary at 3/3. ( isn't the XTX supposed to have a white?) and all other clutching/gearing stock.
Sled slaps to ~10100 and then runs at 10300~600 at full shift and so far has run out to 178kmhr speedo on snow....haven't had a chance to run it hard and see what full shift rpm/speed is on real hardpack or road yet.
It feels like it isn't pulling as hard as it could up top? Is the pink spring binding?
I'd like it to rev out a lil farther to 10800 or so?
And what should this thing do on the speedo on a hard flat snow surface?
What about the Dalton red DPSS-YMR spring? Supposed to be same side belt pressure but won't coil bind and a tad stiffer finish rate?
Is this the right addition to stock clutching on a stock sled to get a lil better top end?
Poss have to either machine the helix or shim it out?
If using this spring what wrap or position?
I want full shift rpm, great top end and solid backshift...willing to sactrifice a bit of gas mileage to get it
My 1st Apex. Relatively new to Yamaha too after 30yrs of Polaris.
Feedback and advice on tweaking the oem clutching for full rpm and top end for trail riding high speed packed trails and lakes.
NOT interested in a clutch kit or mods....just the best setup out of the oem sled.

BTW....
The EXUP was adjusted to factory spec using the ridiculous idle/start sequence.
I have heard there is a better way to set I for confirming full opening at WFO?
I'll be taking a long hard look at a header for this thing that deletes EXUP......IF the header retains the stock midrange and top end......hopefully better top end??
Pricey lil bugger tho especially considering it looks like it doesn't offer any significant power gain?
The EXUP cable design is a gong show of poor engineering...the EXUP system itself is brilliant...poor execution with exposed pair of cables in a watery enviroment
