Looks good! Other than the Doo engine (gag, hurl).

If you want some lighter drive train parts PM or text me. I have a couple magnesium cases from that era that I modified to fit the lighter Wildwood caliper, Aluminum ceramic brake discs with 7075-T6 aluminum hub, Titanium jack shafts, Holz gun drilled Chromoly drive shaft, triple roller chain and aluminum sprockets. From my competitive hill climb days.

I'll see how i like the concept before adding mods I suppose......

I don't mind the doo 800r, little slow revving but makes respectable power.......
Plus i have about $200 total into the motor.

(Sold more parts

Turning this thing into a snowbike.

Well the sides of the tunnel will be reused, that's about it.

WTF? What did you tell the kids about their sled? LOL

VERY cool project though!

Sheetmetalfab · Oct 22, 2016

Picked up the kids a different sled.

22 slices and 5/8" added in to replace the .045 bandsaw slices.

Very cool

Awesome job.
I really like the way this is turning out.
It looks radical.
Every time I see something like this it makes me wonder what it would be like with a cat laid down motor and bdx diamond lite drive.
Keep up the good work.
Your doing a great job!!!

I am wondering where your fueling this beast from?
I was expecting your exhaust outside the front like a 2-stroker mx bike and filling in the engine compartment with a tank?!
How much fuel do you plan on housing?

Super cool build!!
looking forward to seeing your progress!

I was with you. Sort of. I was expecting the cylinders to be turned around on the cases so the intake could be routed up to the steering neck and the pipe out the back, and the tank under the seat.

Not so easy with the reeds mounting to the case.
And the cooling path through the cylinders would leave a super hot exhaust. Etc. Etc.

Fuel in the bike tank and a mid sized tank on the tunnel with a transfer/vent hose. Probably 7-7.5 gallons total.

If I stick the pipe out the front that would put the motor forward into my legs.

Besides as it is now i can enclose the pipe and have consistent pipe temps.

I had a 2010 m8 in the garage and stared and measured quite a bit before selling the thing....... (spare sled)

The lay down motor plus the overall height of the pipe TB's etc would make the bike 5" taller than it is now to keep from sitting on the pipe. Believe me I wanted to make that work...........
