So far I have broken a rod but then again I believe the rod breakage has occured on the drag only engines but I believe I heard one report of a street ridden one breaking a rod. I can say for sure if I break one the way I ride they definitly have a problem.:yes:jfritz_drfritz. said:1. You can purchase a Jims motor from a harley dealer and have them service it. See what kind of response you get when you phone the sales dept at S&S.
2. Various sources have noted that the S&S 124 has a nasty habit of breaking connecting rods.
3. The S&S catalog touts the virtues of the VFI fuel injection system. Try phoning one of their "S&S certified" programmers - I did and every one of was either not interested or tried to talk me into a power commander. Also nice that nowhere do they mention that their tuned injection system won't fit on a bagger with lowers.
4. S&S has unresolved issues with the twin cam patent and is currently being litigated by HD
5. Performance seems to be roughly equivalent as far as I have seen on dyno charts

These are real numbers you can look to get 118 -123 hp and approx the same tq. There are several versions of the 124 though but the base model is making about 1 hp per cube which is great, but those that think that you will get 130 TQ from a 9.1 comp Jims, Not going to happen, I have dynoed plenty of the 120 and they run great and as I said put out approx 1 per cube. With more work to them they become a really great running engine, but that equals more money.
Ok now if you where to take your current set to a 114 you would be money ahead and make more power. And retain your factory cases, many place there are tons of hoops to jump through when it comes to swapping cases. ANd not just state/ fed regs but with insurance comapnys. Like it or not you need to do the right thing when changing serial numbers on the cases. Wreck the bike and find out that the insurance company tells you that YOU failed to let them know about the engine deal and have them tell you that they will not cover it is a VERY real deal. Been there done that, THEY will leave you holding the bag.
I like the Jims over the S&S but for money spent I am left wondering why?? Why spend that muchmoney when there are less exspensive ways to build a engine??
Wrench,HDWRENCH said:Build cost can vary depending on the level of performance you want but The cost is much less than buying a crate motor, and will out perform it as well. WE have been making 130/130 on a regular basis with the 114 with out ANY trouble and cost wise approx 3000 less than a crate motor. But again some guys have a big t/b and a sert and a good pipe or have a source for a use unit and so on. Please give me a call ans I will be happy to talk to you about a 114/

Even in C$ the unassembled motor shouldn't be more than $7500. I haven't heard how much they are selling the assembled motors for.wyodude said:
