I would like to say kudos to Ultimax. I purchased a belt from them in April of 2022. I used the belt the last part of the winter of 2023 and put 800 miles on it, i wanted to get a few miles on it, so i switched out my other Ultimax which had 1,800 miles on it. In March off 2023 i noticed a cord...

My 2011 nytro xtx with a 1.75 backcountry and hindle exhaust will do 91mph in 660ft on draggy and 106 on a snow-covered trail all with 14,000 miles lol

My limter straps were in the 3rd hole, just put them in the 2nd but to mild slushy to test, I am still playing with my center spring also, cat 160/260. Great on trail but if there is snow where the skis floats it is very unpertucable.

Just bringing this back up for suggestion, sled is great on trail, no issues no dating, tracks straight, but if you have to go off trail( leaving home to get to groomed trails) if there is snow where the skis float it wants to throw you off, tried shimming, adjusting ski shock, center shock...

I have 3 belts here, 2 for the winder 1 for the Nytro(Nytro had less as i was running it around the yard), all 3 had what you described on them, i just took the airhose and blew them off, nothing was embedded and it was on the surface. See what happens.

No laughing at all, all learning. Now you have a baseline for the tune/conditions you had. Only thing i would do is use the tune you are gonna ride/race with the majority of the time.

Wellll how is it running, assuming you some baseline draggy times, or gonna keep the competition in the dark..lol

Yes they do, td recommends. .020

Keep it simple, put stock pump back in, check all lines, filters, etc when doing so. Start chasing your tail real easy.

Put stock pump back in and try, quick and easy.

I was in a large field so i had lots of shutdown room, but the Nytro was only doing 90/91mph. I only made 1 draggy run with the winder on the 290 tune(before changes that i have not tested yet, now running 3inch td stock mod, larger fuel pump, flashed to 290 lean), speed was 105, assuming you...

I would make 2 runs(3 if it was a bad launch/rev limiter etc) making sure they are valid and consistent, then i would make 1 change, you can chase your tail real quick making two many adjustments at once( changing a helix and a spring at the same time, ex which made you quicker/slower) . I tried...

As sideshow said any and all is good. Last year i dialed my nytro in on draggy, made 25 runs in the morning/afternoon in a field with snow with no tracks, kept moving to the side to keep each run equal. Started off running 7.64/7.67@88/89mph to finishing up running a best of 7.49 at 91.44 and...

Very good explanation for the guys who think mph wins drag races, et does, not mph. PPl look at mph to much. i'll be interested to see mine this year since i made major changes since that run, 3mm taken off secondary( locked down secondary), got rid of d the ggb can(came on sled, would never buy...

Notsure if you get the ms17 lean as it requires the big pump. I ran ms17 last year with 91 and no issues, but I don't run wfo for miles, 100%trail ride with sine 1/4-1/2 mile run thrown in.
