Don't trust the rev counter...

When swapping out an ECU to a DP RACE ECU will the limiter change its cut in range ?

Depends on the bike, I know that the 696 goes up, but not for the 796/1100

And I know that running a duc at high revs is a bad idea.  It's why they dont run ducs during the IOM TT... that kind of constant high rpm racing suppsedly kills duc engines.

Hahaha, this reminds me of my motocross days, when the 4 strokes started coming in, on two strokes especially 125's you wring its neck and pretty much control power with the clutch. Kids coming off 125's and riding 250F, poor dads(of fast kids) were rebuilding clutches and engines almost every race! Anyhow, when I finally got my YZ250F, which actually revved higher than a 125, if you believe it, I had to learn to ride it different, going off jump faces, you didn't dare chop the throttle or you were going for nose dive(an experience I had when I brake tapped and stalled it mid air, lucky I had a good trajectory for the landing). Rev limiters cut all forward momentum, and in the dirt, where one's body position is usually forward when on the gas, it throws you forward, YOU KNOW IT!! I thought I'd share this one.

Whoaaa, hold up.  I have been going about this all wrong---usually shifting around 4500rpm.  Didn't know I was missing such sweet music. [immediately runs outside to ride bike, front door left ajar, water boiling on stove...]

To be fair, this is my first Duc (got it 3 weeks ago).  My other bike is a 78 Honda that is ALWAYS at its tach limit 'cause that engine has seen better days (plus it's just damn fun!).

Thanks, folks.  Learn something every day.

Hard rev limiters do suck.  Though I remember once on my M600 with no limiter trying to ge through a yellow light and hitting over 12,000 rpm.  I upshifted and it came into the power like a turbo when it spools up, not what I was expecting at all

i love the "accidently hit my rev limiter"...

I keep my 620 over 6K at all times, and my 916 over 5K. They just don't run quite right below those points, I feel like if I let them spend too much time down there the engines will rip themselves apart...

I would think the reason they don't is the ducs before the 1199 just didnt have the top end pull for the sustained higher speeds
