JCZ In just two months of being on the site I've gotten a lot of good info, but often the talk turns to aftermarket products.This thread started on Rineharts which I like, run on my bikes and tell my friends to if they don't have em already. So, aftermarket is good thing in my mind except where motors are concerned. S&S, Zippers, TP, Patrick Racing and many others produce big inch, powerful motors. Jim's is the only aftermarket manufacturer H-D chose to have a relationship with.Why? I believe because as was noted that the Jim's motor in a 1hp to 1" config is reliable.My dealer doesn't seem interested in promoting the Jim's motor. I am trying to find out if anyone know's why that might be before I pop for the $$ to buy one. I'm not looking to find out about who makes the biggest baddest motor I could buy to drop in my SERK. I live in SoCal man, that's a no brainer - - - pull out your wallet and 1000 shops between Dago and La La Land want your business. So I'm cool with the chatter, but was trying to avoid the dicussion gettin round to aftermarket motors.Guy who lives down the street from me has got an 01 SERG that smokes the tires goin down the road with just a twist of the throttle in 3rd, 4th and 5th: BUT he's in the shop more than on the road. nuff said
