[highlight] I have been thinking of the new 113 set-up. Do you know anything about what's involved? Looking at what's available from the MoCo, it seems you need new heads and obviously cams as well as the jugs and pistons. What about the new 50mm EFI unit ? Also, with bumped up compression do you need high tensile studs, stronger rocker arm supports, big roller lifters ? And here's something I know will start a debate; are roller rockers necessary ? Are they really worth the cost? [highlight][/highlight]
Spyder,
You must have the cases milled to accept these larger juggs, you should look at an aftermarket throttle body like Zippers or Horsepower inc 50, 51 mm throttle bodies as these have cruisecontrol on them the HD does not.
With the larger pistons/juggs you will want roller rockers, new lifters. I would look into a schim for the oil pump and possibly changing to a high flow oil pump like fueling. I have not heard you "The recommendation for new heads come froms the fact that on the CVO bikes we have Hemi shapped heads and not dome shaped" The pistons in the kit are for dome shaped. YOu could have your stock heads welded up and redone if you wanted stock effect.
The juggs are currently back ordered last time i was at harley. If your having to have the cases milled you might as well also do the timken bearing.
Is it worth it .... Depends on where your at if your at 94/98 and you want more like 120/120 - 130 / 130 depending on how radical you want to get. Although one knows they can get to 118/115 for the cost of heads / cam / tuning using stock cast piston. Have to decide how much you want to spend and is this much enough or do you need more and do you want to pay for more and possibly give up reliability.
Hope this helps Spyder
