Re: HPA vs. Blackhorn
Art, if your numbers are without any (DJ-) correction factor, they are VERY impressive!!!
The Super Flow dyno is about 10+ % less than a Dynojet dyno!
I had my XR also on a Super Flow dyno without any DJ-correction factor and it was 85hp; 5 more horses than the Buell XB12 on exactly the same Super Flow dyno / the XB12 was 80hp; they also dynoed the XB12 on a Dynojet; it showed 94hp / +14hp.
Here a link that might be interesting to you / Alex is in Germany like your Boz in UK; we dynoed my XR on his Super Flow dyno.

Re: HPA vs. Blackhorn
Wow cool! I did not know that.....that I did not know. Thanks Tom, you put a smile on my face with that info. I know it runs sweet and has more power than any other I have tried and has an extremely smooth delivery. Whatever the figures are this bike never fails to put a smile on my face. The only one I know that can beat my power delivery is Scotty’s 1450 carburetor bike.

Re: HPA vs. Blackhorn
LOL, I like it when you smile! 
and just for fun, you should also test it on a Dynojet!

Re: HPA vs. Blackhorn
Might try to see if I can get the FB on a Dyno, be interested to see how it compares with some of the well set up XR’s on here.
After me you're first
Re: HPA vs. Blackhorn
Hi Folks
I've just got my paws on a HPA (from the almighty TwinMotorcycles). Does anyone have a recommendation for tuners in the UK (north)?
