I also wanted to add that the 124's on granite are not stocked on the shelf just yet. We have ordered one for one of our customers here on CVO forum and these engines are built to order at the moment far as I know. We offer a great price on them and we can rent you the jig to drill your own external oil lines and sell you the kit to install the external lines or you can have us machine the lines internally but this process increases prices substantially because the engine must be taken apart and the cases have to be split to do this machine work properly. The new granite motor we ordered this morning will not be available and ready to ship to is from S&S until July 7 so that should be good info for you guys considering these motors. I run one in my own bike and although I don't make as much money selling crate motors as I do selling complete builds, I believe the quality, the power these motors make and the warranty that comes with these motors serve the customer best for their hard earned money and my shop thrives on giving customers top notch dyno tunes and engines that stand up to the standards you expect when you she'll out the money it takes to play with the big boys without breaking things. These S&S motors are just a fantastic engine from the bottom end up. Their oil pumps move nearly 32 psi on a hot motor running Redline 20-60 synthetic oil in mine at idle. I don't think those motors will have the lifter problems we are seeing or any other problems for that matter because they are so beefed up. The new cases they come in (T2) are cast and machined to accept the Timken crank bearings, their is no modification needed to install the Timken as their were with the SE cases and if you do have a problem, my experience is S&S comes running to help, there's no hassle like the MoCo tends to do. I've seen S&S take care of problems on things that had expired the warranty so you can sleep well at night after a long days ride of you heard a knock or something that would worry you if you were still riding a factory MoCo warranty. Sorry for the long post, I'm just excited about these motors, I run one in my own bike for about 6000 miles now and it impresses me every time I ride it even on just crate form. My warranty is now over so the heads will probably go to John Sachs when the snow flies and we'll crank up the compression to probably around 11.25:1 and burn pump gas at sea level with not hint of a ping. Bottom line, these motors are bad ass bang for the buck and the run very quiet. All I hear on mine with a wrath 3" baffle pipe is the exhaust and when it gets hot, I hear the roller rockers at bit. The valve train with the 640's sound exceptionally quiet. I ride with a grid I build a 120R for and changed the valve springs to a lighter PAC beehive, Feuling race series 120 wall adjustable pushorods and a great set of lifters and his bike sound like a thrashing machine compared to my S&S.
