Bonneville America Forums Forums Technical Forums Performance Mods 68.5 hp

Just fineshed jetting on a dyno ,actuly had dealer do it after mant trys.I have the freak 145 mains 45 pilots TBS needles with 1 shim.Dynoed at 68.5hp@ 6450 rpm and 55.8Torq@64.50 rpm.I am in NY not too far above sea level. ;

Forgot to mention the epco's

NICE Torque reading :-) That's alot better than the advertised 44.1 @ 4000. I'd love to see what my CRS carbs would do on the dyno :-(

Nice numbers! How much did they charge to toss it on they dyno? Also, any idea how that translates to power at the crank on our bikes? I wonder what they dyno for RWHP in stock form.

Have you drilled out the vacuum port on the carb slide yet? Do you plan on it? It won't give you any more HP, but it'll increase throttle response. I imagine that with your setup you'd see a noticable improvement.

I paid 270.00 for the dyno run and jetting on the dyno.

I dont know what that would be a the crank,but i believe a stock bike is around 50hp at the rear wheel.

$270
Ouch, I hope they bought you dinner too.
But well worth it if you get those results, worth every penny.
My dyno dood charges me $30/hour and I do my own work while it sits on the machine. He works on the hogs, runs mine, gives me a printout and I change parts while he goes back to trying to keep the parts from falling off the HDs. I get done with a mod, he comes back and runs it. I asked if I could just run the thing and I think he has gotten to the point that he may even let me run it myself next time. I'm gonna call for an appointment for next wednesday to see what the BB kit gave me and dial it in before the Jaw-ja trip.

Stock, the wheel HP at/near sea level on a "standard" day will vary from around 51 to 54 HP depending mostly on tire inflation and chain tension and condition.
