420cc HF engine

[sportscarpat]

I'd have to agree with Lurker on this one. The 212cc is a nice powerplant capable of plenty of power in a nice small package. I considered the 240cc version of the same GX style engine but after making a few measurements decided the benefits were not worth the added weight and size.

My 2 cents, which is just that......I personally would never try to cram a HF 420cc into anything less than a tandem, for several reasons. The main reason would be as Lurker has suggested....the weight and power of a stock HF 420 and a more practical application of a HF 212cc with a few mods.

I've seen Scott's frames (Silverstate) and a few of his builds and I just don't see a 420cc being a practical or whatever option for a build in that frame without some modifications.

Do what you wanna do though, cuz that's what I do I do like the electric starters on the HF 420's.....you almost need one for that brute

Scotto , my HF 420 pull starts as easily as the stock 212 does. my 74 yo. father pull starts it

Maybe you think the 212 is good, maybe you think the 420 is too much or even better. But here is a link to a guy who used the HF 670 V-Twin. I know you've all looked at it in Harbor Freight and thought, I would love to try that on a bike but it's probably too much power or weight. Well, here is a link to a guy who did it by making his own board tracker from scratch. Tubing is .120 DOM.
