| Got the same JHP/Techtronics on my 999, use it all the time to be honest, had a similar item on my 998S, but have now switched to the race pattern on the 999, brilliant bit of kit to be honest.
As has been said it is switcheable so you can turn it on or off.
I was speaking to JHP re:- dynojet q/shifter via my PCIII but he/they said they've had loads of problems trying to get them working consistently |
