Water cooled engine. Looks like a Daytona swing arm. Just thought someone might find this interesting.

Curious what guts they put in that Banshee engine.  I can't imagine you're getting more power than what guys are getting from the 400s.

Looks like a slapped together tweaker project. No footpegs? So much missing, cobbled together, and still to finish. I don't see $3600 there. Doesn't even mention if it has a title or if the engine runs.
Swingarm and rear brake caliper are Daytona, wheels and front end are 76-78, seat cowl looks like '78

Easy to make way more power than the 400 with the watercooled banshee motor as there are so may options available. As cast 421 top end with decent pipes will make mid 80's hp and almost 100 with some porting.

I knew tweakers who did better work than that, but yeah

Along with the lack of details, they can't even be bothered to drag it out of the corner and take some decent photos. Warning signs right there.
