Just given the bike a blast without the Db killer inserts in.
Motor pulls like a train. Fairly noisy under hard acceleration, cruising speed is fine, idle is quite loud and shakes the ground a bit. Also the whole bike felt more vibey through the rev range. And the AIS pipe DEFINATLY needs pluging in full fun mode unless your a fan of 21 gun salutes.
I'll be putting the inserts back in tomorrow.
