Doruin on ebay $1500 buy now

Hobot · Mar 30, 2011

It is the last best version and its complete plus extras. If you just can't live w/o it
jump on it and spend another $700+ to upgrade bearing support, balance lighten
impeller and way it will go a long time. Price/inflation going up, I paid $1500
for two complete ones some years ago, plus the upgrade cost. One of them
has been in about daily use last 5+ years on a stock 850.

Not me. That extra 13 hp is more than this old man can handle.

Doruin ads brag 58% more 750 power on the torque side of equation. But then again Doruin power graph extends to 8000 rpm > 7:1 ratio = 56k impeller rpm.

I can definitely think of better things to spend my money on than one of those.

Doruin or Drouin?

The Drouin. Although, what's on the ring would still be pricey.

There's also one on the SF Bay Area Craigs List...

I don't know anything about these, so I have no idea which version it is. Asking $1750.

Sheesh - I just looked at the ebay link and it looks like the same unit. Sorry for the double post.

Great! Just what I need, something to make my bike even faster. Like I don't get in enough trouble.
