I went down this road awhile back with one of my first posts. Not knowing anyone on the site, I clammed up when everyone told me to buy a Jim's, or a Zippers etc. A few hundred posts later I have this to say. My dealer will install a complete 113 in my 03 SERK for 5K. He wants 7K for a complete and ready to install Jim's motor. (we'll leave Mr. Zipper out of this for a moment) So a motor swap out books at about 8 hours at $80/hr, so we have another $640. Now I have a good relationship with this dealer and the they know my riding habits. They advised me that I would not find the JIm's motor to me MY personal reliability standards. That'a MY standards just to be clear. AND, the cost would be at least $2,640 more. And, according to them to be legal I would need to redo my California registration to include the VIN on the Jim's motor. Bottom line for me is that once I get done with the other projects I've got going at the moment, I'm going with the dealer installed 113 and save money and hassle. Will there be speedbaggers out there who's taillights I must see on occasion. There's always someone faster somewhere. Even my 150 mph SE V-ROD got beat one day. But, the guy that beat me that day has never gone more than 2,500 miles without his bike being in the shop for MAJOR repair work.
