Default 37 uh

Here's a 37 UH engine mounted on the test stand. Engine has T&O 4 3/8" flywheels. Oh, the test light at the very first is connected to the oil sender for confirming oil pressure.

if this works...

Fuck yeah, that thing sounds very nice. Was that the first fire-up? Musta been warm already, right? Sounded like it settled right into a nice idle.

So that's a low compression 80, brought up to what, 84" or so? And compression came up, too... so, 7:1-ish? I bet that bike pulls real nice. What gears is he running on motor and trans?

That was the second start. First time it fired we had an intake leak and only run for about 30 seconds. Replaced the new Colony intake seals with used oem seals and a bit of sealer. It's now 84.14 something cubic inch. Have no idea what the compression ratio is now past it did bump it up a bit.

Whole lot of bits and pieces of un related 80 inch shovel parts...



and a 80 inch snow shovel...


Here's a 97 inch evo with stupid high compression from a while back...

Had a 30 model DL on here years ago, no need to show that one again.

That franken shovel seemed to spin up quickly. Light wheels?

Now this got me all hot and bothered to build something, which I don't really need to do right now. (nor could I afford it!)
