OK, what am I looking at:

This is advertised as a 122 ci SS motor putting out 280 hp. I have to assume it's boosted somehow, but it doesn't say. I'll bet someone on here can tell me.
I'm not going to ride or buy it, just curious. Also sounds like a lot of bang for the buck.

No way you get 280 at the rear wheel (thats 310 to 330 at the crank) from a normally aspirated S&S V twin on pump gas.

Just my .02

Several things look wrong with this bike. First that MPH doesnt match that E.T. I would also think 280 HP on a slick tire bike would do better then a 9.80 the MPH seems right for about a 8.80 could be a misprint, also isnt that a supercharger hangin off the side of the motor?

It looks like some kind of fuel injection/throttle body, and that gauge on the left handlebar looks like a pressure gauge. Maybe a 100hp shot of NOS. LOL

Nope, not a blower. Looks like an amped-up carb with a velocity stack.

I think you are right

This is a 350 CC Yamaha, Fast lil chit
RD350LC drag bike. John Floyd on a slower quarter mile run at Santapod in 2006. The world record which he holds in that class is 8.87 sec @ 146 mph.

The e.t. and trap speed definently don't match up unless that thing spun through 1st and 2nd gear. It probably is running a 100 shot (maybe as much as 150) of N20.

He could be running nitromethane in it too, some still run that. And with that trap speed he should be in the low to mid 8's, not high 9's, unless it has one heck of a top end charge.

I like the way it is listed as a Harley drag bike. How many HD parts do you think is on that thing?
