What if I told you that you were only ever using 90% throttle

Check this out. Your throttle might be only opening to 90% or a little better (both my engines' throttles are like this)

Will this, if corrected, free up a little more tq/hp on the dyno?

Discuss!

Before my engine build, the triumph tech who worked on bike put a clamp in a place where the throttle was only opening to about 75%.

Dyno showed 12 HP less like that. I'd imagine there's a little gain from 90-100, but not a ton with stock engine.


Definitely one of the little differences from bike to bike that'll show on a Dyno.
This is one of the changes maxxbore does when boring the TBs, he filed the stop so it opens fully.

Good find!

How do you make the throttle squeeze all the way open?

File the stop on the throttle cam

The average rider will very seldom have the throttle open over 20% in fact I would say the 3-10%range is far more realistic.

Throttle? Isn't it a switch - its 100% on or its off?

Surely is.

And of course I had to read it in his voice

On the Rocket I think 90% is enough.
