I have a 12 1100t,and was thinking about jackshaft upgrade,I see the '15 has a new stronger shaft,was wondering if anyone has seen one,or just go with an aftermarket. I have a 2.5'' custom intake and would like to know if it would be ok to vent the Boost Recirc Valve to atmosphere ?I had that on my TRX with no issues.With the open intake the BRV is a bit loud for me.My intake is behind the windshield so you really hear the BRV.I am running a Boondocker 2.0,pretty happy with it but sent it to D&D for the booster reflash to rasie shift rpm to 82-8300.Has anyone tryed leaving the tps wire not hooked to the sled just hooked back to itself,supposedly helps with throttle response.Is it ok to raise the idle speed a little useing the set srcew at the throtle stop?
