Hey Glennbo,
Do you have any idea what you will be using for forks? I have a shockmaster with
great chrome and terrible paint filed for a 3/8" axle if your interested.

Now that's more like a proper frame! Looking forward to your progress, but I still think you're going overboard on the engine

The big HF is a delight for power, but vibrates like crazy.
I rode around a lot today, with the way above normal temp for November. I could ride a lot because I mounted the engine on isolators below and rubber restraints on top. My engine is mounted on a gussetted horizontal plate, I am curious if the guys who mount the engine upright have the same vibe issue.

I have two mounted upright and it does not bother me. I just think anytime you solid mount an engine you are going to feel it.

And it feels like power! I love the big 4-strokes and the vibes don't bother me either.....certainly no worse than your average china girl on a bad day.

What is the goal for a 212cc monster like this engine?

Using the GTC (Comet 30) and a 212cc Pred. I find anywhere between 10 and 12:1 to be the range that suits what I need for power and acceleration. That ratio does not include the torque converter's variable ratio of course.

There isn't a specific goal per se, it depends on what you are going to use the bike for with a maximum sized motor such as the 212cc.

I wonder if that roadmaster frame is compatible with the tanks that sportscarpat makes for the Schwinn Panthers?
