We're just a week or two from this build looking like an actual snow bike. But for now, the devil of this build working properly is in the details.
You can't just take a single-cylinder, big-bore two-stroke engine (and a 28-year-old one at that), drop the trailer ramp on a 10-degree F morning and have all be right with the world. It's probably not going to be smooth sailing.
To correct that, Evan Hoge (builder and also Klim Product Line Manager) is counting on a little magic from Starting Line Products and Thunder Products. SLP modified the carburetor as part of its cart-engine build on the CR500R powerplant. And to help the bike adapt to the cold air, fluctuating barometer and rapid elevation changes, Hoge is installing an Intelajet system from Thunder Products. In a nutshell, the Intelajet adds two nozzles that spray an additional fine mist of fuel into the carburetor's airstream--all adjustable by the rider via an external knob. Hoge will be able to make adjustments to the fuel delivery quickly and without tools. (For more info on the Intelajet, click here: https://thunderproducts.com/thunder-products-intelajet/ )

There's an old-school carb with new-school fuel injection. Just not electronic...
Now, about that custom pipe. Hoge says that when SLP's Allen Roberts offers to hand-build a custom pipe for your build, you drop everything and get the bike to his shop ASAP. Roberts is one of the best two-stroke engine gurus in the world, and has been behind decades of sucessful performance exhaust systems that SLP has produced.
If you sucked at math in school, pipe building is probably not for you.
This is about as much of the Allen Roberts handicraft Hoge is letting us see so far. Just don't miss Hay Days, where you can see the finished bike and this sick pipe.
