Dyno - 4/5/2008 1:27:47 PM

I had my bike dyno'd today, and I only got 95.6. I was curious, do different dynos rate bike higher or lower?

I have a Barnette kevlar clutch with a Two Bros pipe, K & N air filter and a 520 conversion -1.

My friend did his all stock and got a 93.

Did this guy who dyno'd it do it different, he rolled at full throttle in 5th gear for the peak test. Any advice?

Weather - dyno - etc all will play a part. That's not outside the range of what I would expect.

I'm looking forward to getting mine dyno'ed this season. A local shop is having Dyno Days on Wednesdays to try and bring in the large riding group we have every week, and $25 gets you three dyno pulls. The same shop wanted $350 to do a full tune, so I'm hoping they'll bring it down on those days.

numbers will vary some from dyno to dyno. they will also vary from one run to next on the same dyno. usually, when you get a bike dyno'd, they should make 2-3 runs, and usually throw out the first one. for some reason the first one is always a little low. I dont know if its becuase the bike is usually cold or what.

They did 3 runs and the 3rd was the best. But i don't think this guy has ever tuned or callibrated his. He got it on Ebay and has only had it for about 4 months.

Every Dyno is diffrent.

Keep in mind also..

That weather and elevation play a HUGE HUGE part in a Dyno.

If it's humid you will lose Horsepower, if you live in the Mountains high above normal elevation where the air is thin you will lose horsepower.

you could Dyno your bike one day then the next day dyno it and get 5-10 more HP then the previous day.

just works like that.

Thats pretty close to what I got with a JArdine midpipe, a PC and a tune. What brand of dyno was he using? I believe that brands differ somewhat, and also lots of day-to-day variability, operator difference, lots of other factors. Compared to a bike like a Bandit 1200, adding power to a f4i is going to be very expensive and come in small increments. I was fine personally with the power of the stock F4i until I changed exhaust to get more ground clearance. Then I had dyno tuning to smooth out the curves. You wont get optimal results just by adding a PC and downloading a map. I doubt any F4i would make much over 100 hp without help from Erion and HRC on the same dyno you ran.

Depends what dyno it was done at, what settings were used on the dyno, etc. Like others stated weather effects dyno.

With mods a LOT..Better throttle respsonse over and above what a downloaded tune does.

Mine is smooth as butter and gets the same gas mileage now as it did when it was stock but making more power.

Sounds about right, I got 94. Depends on the person running the test and the equipement. I've seen the mobile dyno trailers tend to run a bit high and may not be accurate.
