Delay'd shift into 2nd gear under full throttle

[Wildrice]

It is. Maybe "passing thru the neutral selection" when going from 1st to 2nd has something to do with it?

Could be Chuck, I've had air shift solenoids on 3 bikes & never encountered this magic delay.
But worse yet--I've misplaced my 2 cluster 6 speed tranny from a Hayabusa. I hate misplacing things:bdh:. I was going to take a few photos & attach them. considering the consistent delay & the short distance the gear forks have to move the gear--it seems unlikely--But I don't have a better idea. Someone on this forum stated they have the same problem but in a different gear change. The gears usually only move less than 1", especially being consistent. Stock ECU's should be flashed the same. Could it be a marginally weak solenoid --not impossible I guess but seems unlikely. The delay seems like it kills the engine which is what the air shift sport bikes do(ground out the coil packs) for approx 50 milliseconds . Which makes the problem an engine kill delay time[. I think "Diginurds" are involved ...

I Think He's right wild rice The problem is of the solenoid too slow, I on my previous bikes I always had the power shifting, and I had never problems to do 1 °-2 ° even at 14 RPM!!!!!

If the problem is with the solenoid causing the delay--the tach should show bumping the rev limiter--does yousr bump the rev limiter during the delay??
Most motorcycle tach's read a few hundred RPM higher than actual RPM at maximum. The Hayabusa's were off by 400 rpm. If yours is stock ecu set at 8100--run it up into the rev limiter in 1st or 2nd gear & see what the tach's rpm shows.
If have the stage 2 MFI upgraded ECU set to 8600 & I've seen 9000 rpm on the tach.

If the problem is with the solenoid causing the delay--

What I meant by possibly being too slow, is that it just doesn't react fast enough to make the shift so the ECM/TCM has to hold the delays put in place for the request. Again, logic would state that this would happen in all gears.... but depending on the programming and what the parameters on your specific byke are at the time of the shift request may "create" the problem. As does mine at whatever the throttle position/ECT/IAT parameters are when it happens.... Gonna prob be one of those questions that never gets sorted out fully....
