Dyno results....Re-dyno after reflash?

[peterbaron]

I just had my bike Dyno'd today. I have a TSR air funnel K&N air filter and a custom slip on exhaust from cone engineering. I had the mods on before the tune. The baseline was 86.39 hp and 68.22 torque and I ended up with 91.19 hp and 71.40 torque. I'm pretty happy with the results. I plan on getting my bike reflas he'd in the future to remove all the de tunes just to have a little more response and a little more on the top end doesn't hurt. My question is would another dyno be worth it after a reflash or will the reflash just improve upon my previous dyno?

Not to offend you
theoretically.. 4.8 HP & 3.18 torque more = = sorry, but for me not worth digging (compared to baseline). How much did you spend on mods?
I'd like to see results BEFORE mods, for further assessment please.

pb The benefit is in cleaning up throttle response, reducing driveline lash (fuel cut eliminated) and popping, more efficiency, and generally improving the rideability of the bike. A little bit more power but an improved power band can really help the feel of the bike.

That said, I never did get around to sending my ECU to Don Guhl because the 2013, mine anyway, ran very well.

I would not want to think I'd have to reflash a 2017 to cure any problems. I hope they've gotten that sorted out with the Euro 4 and so on.

How about an image of the dyno run to see the entire powerband?

Dyno image BEFORE and after mods, otherwise not interested...

Generally agree with your statement ULA..makes logic sense...I used to modified 2-stroke engines with very great results (much cheaper/easier than 4-strokes)....four decades ago = history.
My point is , that aftermarket engine electronics offer so much bull poop in "increasing HP" that, I want other members to be aware of it, before $pending. Your bike, your time, your pleasure/satisfaction and money spent....is it worth it in this case?.. I someone tells me this: I have larger: valves, intake/exhaust ports, diameter exhaust pipes, higher volume fuel pump/injectors, different shape of combustion chamber, lighter pistons, with connecting rods, cams!! and completely reprogrammed ECM +++ more = big bak$ spent = for sure more power...now another issue comes into consideration:: pollution, heat/NOx.....and there we go again into another "argument" = friendly
Hope to talk to you soon

So easy to work on 2 strokes!
Before Yamaha utilized reed valves on the intake (1972?), a fair amount of HP was easily gained by skirting the intake side of the piston by ~1/4 inch and by replacing a stock exhaust with an expansion chamber.

Thanks for the walk down memory lane.

+1 and even more and more, enlarging ALL ports/canals ++++...still love 2 strokes!!!!!!!!!!!!!
