Hello, I have a 2006 RR6, And I had the intake flapper done so it stays open but I have put a power commander 3 on the bike takes about 5 attempts to start from cold, but if I close the flap it starts first time. I have been in touch with Dynojet and they haven't been able to find out what the problem is. So tonight connected the vacuum pipe back up. But now when started and in gear when you put a few revs on the flap closes. So for some reason it's the opposite way now. I'm sure that prior to removing the pipe and blanking it off you could open the throttle and the flap would open with the engine switched off Can anyone help with this. Thanks Tony
