Nice bike. I don't know what your budget is, but it seems like you are going to spend more than a cheap dirtbike.

Is it just me or does this thing look like it would fit in some pretty tight confines?

Haven't started a build yet still just looking.

I put the 6.5hp version of this motor in a beach cruiser. I'll post some pictures when I figure out how...

I think I figured out how to post a picture. Try this link.

SDP....good job there. Im sitting here now drooling over that HF 6.5 and wondering how it would look with a 49cc sticker on the shroud! LOL! Nice job!

How fast does that thing go lovehamr? Do you have to strap your hands to the handlebars to hold on? What size of sprocket are you using? Nice looking build!

A new BIG engine (not really big lol) for the bike! ON THE BIKE!

It's 79cc and 2.5HP @ 3600RPM, so this baby should have more torque than a Honda GXH50.

I just got one of these engines Friday, and I'm awaiting my 4 inch 40-chain Hilliard Extreme-Duty Clutch for it.

I plan to mount this engine over the back wheel and use a chain drive. Similar to what the Honda GXH50 guys do, but with a larger engine. Shipping sticker on the box says the engine weighs 24.8 lbs, so it hopefully isn't much heavier than a 50cc 4 stroke. Either way, all that matters is that it will mount up properly, and I can keep the bicycle safely balanced and not fall off.

You will be happy to know that the HF 2.5 engine can be rack-mounted and won't throw the balance of the bike off. I just tried my build out today, and the only time I noticed the extra weight on one side was rolling the bike around to a pole to lock it up. I have a friction drive not a chain drive, so my weight offset is likely as bad as it can get.
