Building a LIGHTWEIGHT Mtn Sled Part 2

[@skidooboondocker]

I love Carl’s sense of humor, makes me laugh!

[@Justgaragenit]

That’s an awesome build. Really cool to see your able to shave that much weight. Even with going with a larger skid/ track

[@CarlKusterMountainPark]

Thanks, we have some fun updates in the near future!

[@jackcoveproductions]

Fantastic project, I am amazed at the ready to ride weight savings already!!!!! your killing it Mr.Kuster! I can't weight for the end result......lol

[@KyleHaley864]

Where did you get your Titanium fasters like the clutch bolt and other bolts?

[@jgofast9249]

What does the lynx weigh? I read they drop some weight form the factory.

[@hebbs68]

Very nice !! Do you know of any one that makes a flat gas can that hooks in 4 linQ brackets and also you could stack a 4 bracket bag on top of it ?

[@CarlKusterMountainPark]

Backyard Bolt-Ons has a 14L prototype that is exactly what you are after.

[@hebbs68]

@@CarlKusterMountainPark thank you I’ll check it out!! Thank you so much !

[@800tundra]

Speed holes , need to drill lotsa speed holes. 😜

[@IdahoMthman]

Great series. Thank you for sharing. What is the cost for this light weight build?

[@CarlKusterMountainPark]

This current build is roughly $8,000 CDN in parts listed in the description. We are still in the experimental stage with hopes of one day having a refined product for Ski-Doo owners.

[@beeh1763]

Was curious which machinest you got to make the p drive titanium flange bolt?.. and wondering if it messes up the weight of the clutch?.. was thinking about sending the chain tentioner bolt away to get made as well...

[@CarlKusterMountainPark]

We had all our bolts titanium and aluminum made by a company out of NJ, Very timely process as we had to take measurements and create CAD files individually and now that we are on the Gen5 platform as well as learning lots of what we need more of in titanium vs aluminum we are hoping to find a supplier a bit closer to us on the west coast. Regarding the pDrive flange bolt, we have never had an issue with the clutching throughout numerous builds.

[@beeh1763]

Thanks for the reply! I ended up ordering some short stock rounds online and maybe found a machinest in williams lk that can do a nice job with the flange and tentioner screw :) they should start coming stock built out of titanium lol

[@susanhenderson2322]

What is the cost so far ? And list of parts # would help

[@JBracing2s]

Where do you get the titanium bolt kit

[@CarlKusterMountainPark]

We have them made for our projects, they will be for sale in the near future.

[@quentinstore1464]

Why not put a belt drive on it?

[@CarlKusterMountainPark]

Takes up to much valuable real estate on the right side.

[@JBracing2s]

Where to buy the titanium bolt kit

[@CarlKusterMountainPark]

We will have them in stock soon.

[@jackcoveproductions]

when are ya going to have part 3?

[@CarlKusterMountainPark]

Working on it!

[@revrdr600ho]

Why no belt drive?

[@backcountryshitok]

Do you what the difference in weight between the lightweight freeride hood and the rs hood is ?

[@3DProductions]

any reason for no belt drive?

[@208Ridgerunners]

I was curious to this as well….

[@nickraces]

What are you doing for an air intake with the RS hood?

[@20kcstudlee]

Why wouldn’t you bring on the shock not the sled to fit shock

[@adampetten1009]

What spring and helix are you using in the Team? I actually put a QRS on my 600RS because it was a pain getting a helix that worked and had reverse.

[@Yz4Life]

Delete the oil injection! Save like 10 pounds by taking the pump and reservoir off who cares if you have to mix gas lol also notch the track, titanium shock springs save a lot of weight,

[@grgsrvc]

How do you oil the crank case then on an efi motor??? That was a cool weight loss truck on an old carburetor style motor but when you are injecting the fuel at the last moment before the compression stroke there isn’t any air fuel/oil mix in the crankcase.

[@Yz4Life]

@@grgsrvc the crank case of a 2 stroke is constantly bathed in the oil/gas mixture. On higher revving engines you drill passages in the crank case that connect to the bearings and they will be oiled. Oil injection does not send oil to the bottom end. It just mixes it with the fuel before the reed cages lol

[@grgsrvc]

@@Yz4Life you are right if it’s a carbureted motor.

[@grgsrvc]

@@Yz4Life the fuel injectors add fuel to the air after its has gone through the crankcase. Having oil mixed with the fuel in this style of system is pointless.

[@Yz4Life]

@@grgsrvc you making no sense? No air is going through the crankcase lol

[@jordanzagar1622]

Belt drive! -5lbs

[@scp8412]

Totally! That's an easy 5, more like 8lbs

[@gymkhanadog]

So basically you have to spend 5-6k to shed real pounds. I had considered doing all the bolts on my sled in titanium but maybe it's not worth it. I am building a carbon fiber hood and cowling though, that should be good for a lot of weight on my Edge chassis.

[@Ride4life311]

3200 km is actually just shy of 2000 miles
