Will do. I've contacted them before about fitment of mag alt covers and they were very responsive through email. Needless to say, I moved their bookmark near the top of that folder - I was impressed.

Update

This project is still alive.

Billet 30mm offset triples are "on their way". This puts at the point of "rolling chassis", almost. Here's where I'm at:


  • Frame with Aluminum Sub-frame, connected with titanium bolts
  • Black powdercoated Swingarm with titanium swingarm pivot
  • AMS billet ride height rod, OEM SBK rocker, titanium lower shock pivot, rocker pivot, and rocker bolts
  • Temporary OEM shock - planned: Ohlins/Penske
  • Temporary 848 forks - planned: 1198 showa w/ ncr lowers+ohlins internals
  • Ti motor mounts (nuts, washers & rods)
  • Carbon headlight bucket
  • AMS / Ducati Corse 3-pos (6-hole) billet rearsets & Ducati Corse heelguards
  • AMS rear brake caliper bracket, OEM eccentric hub, axle, ti eccentric pinch bolts
  • Motorize.de billet rear brake master bracket, AMS / Ducati Corse billet rear brake lever, Ti pivot bolt
  • Blackstone Tek 5-spoke Carbon Fiber Wheels
  • temporary "mock-up" tank, bodywork, airbox, etc

Motor parts

  • VeeTwo Lightened, straight-cut primary gears (primary, driven, and oil pump gears)
  • VeeTwo Billet, Adj. Cam Shaft Pulleys
  • DP Billet Pulleys (for layshaft)
  • VeeTwo "Race" Cams for 900, valves
  • MBP Collets


Planned Motor Parts left to acquire:

  • 94mm or 95mm Pistons (Pistal, JE, or Mahle). Goal is 95mm for a "966" SBK, using modified 996 logos
  • Lightened, balanced crank
  • The ol' port and polish
  • Factory Pro Shift Kit
  • Febur / NCR oil cooler
  • Keihin FCR41 Split Singles with a few modifications
  • Ignitech TCIP4, using layshaft pickup with tachometer/shift light output
  • Mag alt & clutch side covers
  • Ti case joining bolts - the big ones that join the two halves

(By the way, shout out with reviews, comments, suggestions for plans, as we are in the 'gathering bits' stage)

Chassis, Brakes, Bodywork Plans:

  • Single HID projector through race fairing, mounted on CF HL bucket I have, with ballast sitting next to it
  • Brembo monoblock radial calipers. Billet if budget allows.New T-Drive rotors if available
  • CF bodywork - single piece sides, race front
  • ETI tank, or Alu tank, or CF tank
  • Motogadget or 'Race' dash with giant tachometer display and minimal speedo
  • NCR clipons? Perhaps CF bars
  • GP or RCS Master Cylinders, Folding Levers
  • Ohlins adj steering damper

did you buy those bst's used or new? are you doing the pairs to split mod? i told taft, but i was a very sad day earlier this week. there was a complete split 41 set-up w/ manis FS on ebay for $750 and sold before i found it.

No, using some dirtbike keihin mods to the split singles, buyin' 'em split to begin with, not banked.

what are the benefits of using splits to paired other than PITA tuning. i know using shorter manifolds affects the power curve. i remember when i was going to use ITB's on my vw, using short to long runners, one would benefits torque and high rpm's.

Short manifolds = most top end power

(note, this is a track-mostly bike, so that is ideal)

That's a hell of a build sheet, can't wait to see the progress.
Every bike I've ever owned.

Since we're spending your money, I'd say Pistal or Mahle slugs.
Forget the JE's.

That's what I was leaning towards, especially since Chris K has the Mahle's in 95mm, and they are box-in-box like Pistals (don't know if JE's are).

Here's pistals next to OEM (for an 848):


And the Mahle's:

The 92mm JE I've got are old-school; full skirt, no box-in-box.

Please forgive my ignorance, but what does "box-in-box" mean when referring to pistons?  From Speedog's post can I assume it has something to do with the piston skirt?

Also, why are the Pistals such a pretty cool of silver and the Mahles are darker?  Do the Mahles have a different coating?


junior varsity

Box in Box is the bracing on the bottom - it is shaped like a # sign, rather than just the two bars the pin runs through.

Pistals are machined, I know that, I do not know about the Mahle's coating (yet)

i'm glad you asked, i was wondering the same. after looking at the pics i assumed the box in box was referring to the additional brace that runs parallel to the wrist pin.

I don't know what the coating is on the Mahles or Pistals.
