Then it weighs the same as a nytro mtx. Nice sled
Thanks !
I saw a Nytro MTX 162" with Timbersled skid, fox floats front and back and no turbo but with trail tank weigh in at 644LBS full of fluid so its close.
My friend whos has tried lots of sled said that it feels like a heavier PRO RMK and not like the Nytro, i have almost no expereince of the Nytro but will compare it with both the Viper and Nytro this season (and other sleds i can get my hands on).
Now its time to ride

Still waiting for some good snow, so i made some small mods.
A lower riser, feels much better.
"Blockoff plate" in the front.
Another short clip, didnt have my helmet on so it was Cold...

During my last ride i had some over boost but i found the problem.
The hose to the Wastegate was rubbing against the "airbox" cracked and came lose.
way to tight.
I had plenty of material in that spot so i grinded it down and attached the hose again.
Made a short test run to the gas station and filmed the ASA Pro front shocks in action.

Awesome build. Loving the grafting job, the RMK front was most impressive.....but for me.... the doo tankage was even kooler. It definitely fixes some of the weight balance issues of the nytro. So turbo'd, your coming in in the low 600's (pounds) with a full tank? If my gutted NA MTX is coming in a 565, a turbo is a 35lb (16kg) add??? Make sense?
Thinking turbo maybe next year, but don't want a huge weight adder for the extra 40HP. I'm probabley at 145Hp now.
Great build. I hope you put a tonne of miles on it!!!!

Thanks !
Its actually a Lynx gas tank, similar to Ski doo but narrover.
It may be a bit on the heavy side but the weight distrbution probably is a bit different.
there is a couple of easy pounds to remove but where do you start to notice it ? 10-20-50 lbs?
the difference between emty and full gas tank is not dramatic.
i think i will tune and refine some stuff and maybe up the boost. But for a much lighter sled i probably start with a chassie from scratch. I have some really cool ideas but it will have to be a later project.

Sorry for the lack of updates but the weather took a turn in the wrong direction we pretty much had melting temperatures and rain since three weeks back...
the trails are ice and off trail its rock hard snow.
Drove a couple of miles but it sucked and i drove back home.
we have one trip planned late march but other than that i dont think there will be much more riding this season.
I have been talking to Erik at McXpress and i think im going to up the boost a bit as a summer project.
With a thin headshim and increased fuelpressure 210-220 hp is possible. Extra injectors and IC would need major rebuild so i dont think i will go that route.
If im able to get a IC installed there is an option to rebuild the stock injectors for more flow at a reasonable price, that would be a interesting option.

Still no riding and it sucks, next week we are going on a trip so i got some inspiration to make some progress.
Scratchers installed.
Started on some covers to seal the gap in front of the gastank and the brake caliper that i had to make a hole in the side cover for.

The weekend trip was really good with nice weather but the snow was hard as rock, i was really happy that i installed the ice scratchers Before the trip.
rode about 400 km in total and the best part was that i got the chance to try some other sleds and see how my sled compared to them.
When i started my build i had not owned a sled since 1998 and never ridden a rider forward sled, so i put it together the way i belived would be a good sled.
The first day i lost a nut from the left upper ball joint but saw it in time Before i destroyed the spindle, thank God Polaris has metric bolts nowadays, i could borrow a nut from a friends ice scratcher and i was good to go.
In the fleet of sleds we had a Viper XTX with MCX 190 kit on it so i tried it and my sled had a bit more power so that felt really good, my cheap home made turbo kit is working better than expected.
But the handling of the Viper surprised me the most!! it felt bulky and did not sidehill with the same ease as my sled (i know the XTX has wider ski stance)
after that sled i tried a M8000 and it was better than the Viper but i still prefer my own sled.
Finally i tried an Assault and felt more home on it, easier than my sled to handle even with the wider ski stance, But when riding the Assault i found out what has been bothering me on my sled. I have the handle bar way too far forward. that will be my next mod.
the day after i got to try a Nytro MTX and it had nothing in common with my sled other than the feel of the Engine until my boost kicks in.
some pics.
When piercing the hard surface there was lots of snow.
