New Custom Mountain Sled Build

Today was pretty productive. I have a few days with no customers' shocks to work on, so I needed to take advantage and get a bunch of stuff done before the next round comes in.

I got a new crank from Ski-Doo for a rebuilt price. I also got all the parts back from being hot tanked and cleaned. The Iso grease showed up today so it was time to start putting it back together.

I got the lower end all put together. I also installed the new recoil ring and the new recoil. I installed all new seals. The PTO and MAG main seals were replaced. The waterpump gasket was also replaced.

Everything was cleaned before being put back together. Here are the shots from today:















 
I forgot - Kelsey got the cheater done up. I should be getting that in a couple of days, he finished it up earlier this week.

The cylinders are done at US Chrome and at Big Johns waiting for the new pistons to get the correct base gasket.

Here are the shots of finishing up. I put the MAG and sensors and flywheel.















 
Nice job....keep up the good work!


Thanks. I just spent 13 hours today in the shop cleaning and putting stuff away. I have the old mountain sled and the trail sled off to the side. I have a clear shop to start work on the new project.

I just have to put a new reverse chaincase in my wife's sled, and add E-start then I can start the actual build process.

I am going to be bending my own tunnel on the this sled, too. It is going to be similar to a VanAmburg Boondocker style tunnel.
 
Well. I'll keep you posted for now. But I am not paying to use the site when it goes PPU.
I got the top end stuff back from Big John and dropped off my pistons to Cool Concepts on Friday. I picked up my pistons from Cool Concepts today. Rick does excellent work, excellent prices and superior work. Kudos to him.

Anyway. I done with the shocks around 6p, so I decided it was time for a little "me" time. So I dropped Rob Zombie Dragula on the CD player and started to put the motor together.

This is a good shot of the quality of work Big John does. I can't imagine anyone taking of business better than he does. Big John and Sled Head Racing are top shelf all the way.

Kelsey's head machining is second to none. Everything bolted in place, everything dead on....and it still looks like an ordinary 800HO motor.....mo-ahahahahahahaaaaa.

I assembled the motor with Ski-Doo mineral oil. That is all the all the oil I use, even when riding. That is another thread at another time.

Here are the shots from this evening's build:







Here are the pistons back from Cool Concepts with the Thermal Barrier coating. Big John's pistons come with poly on the side skirts.



The old RAVEs were junk from piston contact. So I have BJ machine some new ones from a good set I had here.



These are the new caged bearings that went into the brand new 800HO rod:



Ready for final assembly with bearings, wrist pins and circlips in place:











This is installing the Boyesen reeds. I will get stainless bolts to hold them upon install in the sled:



I always use Nordloc washers on the Y-Pipe. I have the pipe installed for now to keep dirt and the like out. I will be sending that in to be coated in matte black high temp along with the expansion chamber and HPA can.





Done....looks completely stock.
