Bianca aka. my take on the 2V SBK

[DRKWNG]

You're going with a monster tank? What happened with the SBK tank?

You're going with a monster tank? What happened with the SBK tank?

The SBK tank was/is upstaris. The monster tank was sitting on the ground sad and lonely. 

Since I'm not using the SBK airbox, I need to make a braket to connect the pin on the front of the tank to the frame before I can put it on the bike. Then it's time for the rear subframe and I'll need to figure out where I want to put the battery (the Shorai). I'm thinking either above the vertical cylinder (stock monster position), or above the horizontal head (and below the air filters), or maybe back in the tail (some re-wiring may be necessary...  hmm Italians and electicity).

Pepe ...  What year 900 motor did you use that did not line up with the 748 frame ... or was your 748 frame a 2000 and newer ..
I am looking at using 1998 944, balanced / blue printed, v1 v2 heads, ported, larger intake and exhaust valves, ST2 cams, 41mm flatslides, and a STM slipper clutch .. 92HP dynoed at the rearwheel .. 1996-1998 ..916/748 frame and swingarm..

[junior varsity]

all 600/750/800/900/1000 2v motors will not line up in any 748-916-996-998 frame.

[desmo916sp]

So i see that the 916 cases have the SSSA axle hole in the low position .... so .. questions.
1. if i use a 749 / 999 frame .. will this allow me to use the 900 motor, being it has the OBLONG holes ... if so .. 916 SSSA or S2R swing are .... what shock rocker or adjustablerod do i use .... and lastly .... the if i michine the Left and Right side of 900 engine cases .... is there needle bearings or something in the case that far to help support SSSA axle ..?? all your knowledgeand advice is welcome ..

you still have to machine the cases to be narrower in order to fit the swingarm between the cases and the frame.

The 2 valve engines (Monster & SuperSport) have needle bearings inside the engine cases. The superbikes have the bearings inside the swingarm so the engine cases are hollow. There were actually 2 pairs of needle bearings on each side in my engine cases. The outer ones got trashed when I cut through the cases, the inner pair are still there. I just put some grease on them before sliding the axle in.

A 749 / 999 frame has oblong (oval-like) holes for the swingarm axle so you don't need to cut & paste the frame to make it fit, however yes,

you still have to machine the cases to be narrower in order to fit the swingarm between the cases and the frame.

I'm using the stock rear suspension setup that goes with the 748 / 916 / 996 gen frame and swingarm. I think I could have used a 749 / 999 swingarm as well since the layout is pretty much the same.

I Taft has some parts for a 2V setup in the for sale section: http://www.ducatimonsterforum.org/index.php?topic=50355.0 He has the swingarm axle with the offset washers so you might want to jump on those if you go for the 749 / 999 frame (he has that as well, btw).

If you want to use a 748 / 996 frame then I would suggest buying a set of sbk cases and doing an engine swap so you don't need to cut and paste the frame and narrow the cases. In the long term it's less work and a better overall fit.

Good luck with the project!

+1.  This is what I'm doing. If you search (I believe in Tech), you'll find posts where I discovered similar troubles, and found superbike cases with the same cylinder-stud spacing to make it possible to drop cylinders/heads directly on to 'em. (Either 900 era cylinders/heads or 1000/1100/DS cylinders/heads)

 ^ we should probably write a how-to 2V sbk for the tutorials section

here's a bit of an update for me. made myself an undertail of 7075-T6 alu.


and found a nice carbon fiber hugger on CL. I also got a little bored waiting for parts so I decided to paint the clutch pressure plate gold 


Since the horizontal header off a S2r fit nicely I decided to see if the rest of the exhaust would fit as well, and it's a negative.


Sorry for the dark photo, essentially the udder is too tall for the SBK swingarm. I might be able to fabricate some lowering brackets to get it to fit, tho.

If the brackets don't work I'll just return it to the original owner (thanks Jim, you can have your exhaust back now, it's almost like when you gave it to me....  ).

My plan is showing up at the muffler shop with the bike and a bunch of bits (s2r / hym flange, 748 flange, the half system installed and the two intermediary pipes). You "must" have the thing pretty close to assembled to show them how tight the clearance is between the shock spring and the header's intermediary pipe + flange on the vertical cylinder. Ducati left little wiggle-room

I need to shoot some pics of mine in current form - I am headed towards making what i'd like to call the 1079/1123cc "RS" - using bits of factory corse parts where possible. (as in 748RS - the race homologation bikes, not like S4rs showroom floor models)... Dreaming big, I know. Gotta long way to go

Yes you do!!

not so awesome yet - no front fairing still.

But, the carbon headlight bucket is gone, this'll be track-only or using only a projector-type headlight somewhere. The front fairing-bracket is the carbon fiber "RS" type with the much 'shorter' ears to mount the front fairing. Likewise, the front of the air runners no longer attach to the headlight bucket but instead have the posts and bunjee-cord setup from the RS bikes.  What's not "RS" (yet) is the airbox/air-runners, which are Sebimoto carbon versions of the OEM parts - still using the clip-retainers in the airbox to attach the air-runners, and the associated small OEM opening at the airbox as well as at the 'fairing'/mouth end.  The goal is to change those bits to the Q/R setup from the RS bikes if I can find a good condition 3-piece airbox and the RH air runner (I already have a Carbon Dream left-hand air runner, just need the right-hand one).

Motor-wise, the 749 crankcases are in the frame, but are still empty. I stuck the LH and RH case covers on there for 'mock-up' purposes (and probably more so to get some shelf space back).  The cylinders and heads are still MIA, but the 1100DS base gaskets are on there, which is a nice way to remind myself that it can all be made to work.

I have decided to move the 6-bolt wheel from my Monster over to the 2vSBK project and have some 15mm-offset/6-bolt carrier'd rotors done up for it (its got the 1098/1198 forks on it).  So, while there's nothing doing with regards to front brakes just yet, at least the front wheel and back wheel will match - BST 5-spokers (6" rear)


SO, to sum it up, what's left looks like this:

Motor-wise:
Crank/Rods/Pistons
Cylinders/Heads/Cams/Valves
Layshaft, Trans Drum, Trans & Gears 1, Trans & Gears 2
Flywheel, Stator, Magneto, Regulator/Rectifier
Gears: Primary, Driven, Layshaft-Timing, Crank-Timing, Sprag, Oil Pump, Intermediary, Starter
Coils, Plugs, Wires, ECU, Throttle-Bodies, V-Stacks+Filters and/or some carbon/fiberglass re-molding so 748/9*6 airbox bottom mutated for 2v's offset TB's

Body:
RS 996 Underseat (Big-Volume) Breather Box (I know, kind of motor related)
RS 748 Subframe Seat Bracket
Racing Front Fairing (Big air-runner style if I can get the necessary other bits)

Chassis/Suspension/Brakes:
Sell the DucShop 30mm 848 triple clamps in favor of the adjustable offset IMA Special Parts triple clamps
Front Brake Master Cylinder, 100mm Radial Calipers, Rotors
200mm Corsa-type rear rotor


man, when i type it all out, it looks like I have miles to go... Really the engine part isn't that bad. Go grab a totaled M/HYM's 1100DS motor and take everything out of it that I want, sell the rest.


Been having a long spell of being absent from my garage - I take the Bar in about a week and a half. Then I'm moving.  So it'll be awhile longer before I can tinker some more.   I took the exhaust pipes off my Monster in February or March, still haven't made time to put them back on. Now with average highs around 105 in DFW, I dare not go out in my detached, un-air-conditioned garage except for the several daily checks to make sure everything is still there, nothing has spontaneously combusted.

Wow! Sounds like you have a lot more time/energy/thought/money in yours than my project.  Really need to pick it up again and start working on it, that's why I subscribe to all these threads, motivation to get off the couch and go out into the 100 degree garage and wrench.  As it sits, motor out of the pic:

meh, I don't know about thought.   My plan is kind of like copying the RS bikes - where i can, if I can find it, and within reason. 

The RS bikes kind of epitomize the heritage, passion and allure of Ducati in my eyes - these bikes used the most ridiculous stuff available at the time ...and I think, in some respects, still more exotic than what is ridden and raced [at lower levels] with the 1098R/1198R...   

The 748-916-996-998 bikes (and the 999RS for that matter, which had a section of the frame that was removable to facilitate access to the vertical head) got some pretty exotic equipment by even today's standards - such as magnesium triple clamps and swingarms, undertail reservoirs to expand crankcase volume, total-loss charging systems, adjustable brake caliper mounting for different size rotors, rotor cooling ducts and enclosures, multi-piece airboxes with quickly removable panels to access the vertical head and to remove the air runners, coolant tank relocation to enlarge the airbox, etc

I believe the 848/1098/1198's lack of higher-spec 848 models, or factory 'crazy' parts reflects on the economies of the countries that are the 'primary consumers' / world economy.  People were buying up gonzo parts for the 748-9*6-998 bikes with reckless abandon apparently.  That's definitely not the case with the 1098/1198 series.
