Further to this topic , I have just finished tuning a 2006 Classic with the Jardines of that day and my baby street cams. The RAMAIR filter worked very well, I ended up with a real smooth power curve and 172 hp and 163 feet of torque. I have never got better with this combo of parts. Bike started out with the exhaust on board, but stock style filter and a PC USB tune at 141hp. The owner will be pleasantly surprised I think to pick up 31hp and 23ft lbs for fun. Cams and filters and tune only. So now I have 5 RAMAIR filters on the shelf for those who wish to keep the bearclaw.
