Frankenduc Pt. III The B!tch is back at it!!!!

[Steve Bass]

So it's been a few years since the original build and after all this time, the love burns as bright as it ever did...

With me being away from the old girl due to work requirements, thoughts turned to improving what was already a preposterous bike in the interim..

So plans were hatched in terms of what to do with her, and we settled on the following.....

Engine:
Pistal Hi Comp Pistons
Ti Rods and Bolts
1098 R crank and full balancing with rods and pistons
R exhaust cams
head work including flow benching and valve work
new slipper clutch with started bed override
light weight cam belt wheels
full akrapovic Ti race system
Starter motor removed and blanked off
full blueprint and accurate cam timing

Chassis:
CF throttle body carrier (-900gm)
Ti front axle( - 450 gms)
full Ti & ali fixing (-lots!!)
Cleaned and re-gun coating to swingarm and triple clamps
CF clip ons and Ti mounts
Ti rear sets and furniture
Motorised started bed to save the sprag clutch getting continually buggered( she's needing her 3rd!!)

Bodywork:
Full CF bodywork by the same guy who provided the CF for the winning 1199 Cafe Racer at WDW 2016
Repairs to existing RS CF components

Electronics:
Full Aim MXL2 Dash
Aim MXL2 Data logging system with full Nemesis integration
2x Aim LCU One lambda units
brake pressure sensor
Oil pressure sensor
Front Suspension potentiomenter
Rear Suspension potentiomenter

So from starting life as a simple engine replacement, she's finally becoming the full fledged idiot bike she was always destined to be.
As much as I've tried my Aprilias, Blades and Triumphs, friends R1's, ZX10's and such on track, I don't gel with anything like I do with the ol' girl... It's also the engineer in me wanting to build something unique...

The final result??

We conservatively expect around 14-18 bhp extra compared to the current standard motor (and based on previous experience with the piston/cams combo) but much quicker revving with a broader spread of torque and the ability to breathe at the 500rpm increased red line. Fueling will be spot on as a friend is currently building a new dyno with a 250i bought already with the help of the LCU lambda units. That alone will make a huge improvement as she's running very rich...
Weight should be down from the current 164 kg wet figure. We reckon as much as 3 or 4 kilos especially considering the S/S exhaust she currently runs and the full ti and ali fixings diet and superlight CF bodywork... Would be really chuffed to see sub 160kg with a full (23ltr WSB) fuel tank.

So anyone not familiar with Frankenduc (Daisy) do a search if you like but stay tuned.....there's more to come

One of the few threads i will follow........

Interesting Steve. Really Interesting.

One Q from me though...

Any particular reasoning behind the use of AIM Gear over Motec or Marelli etc?

[Biker's Nemesis]

160 kilo wet weight, what power are you expecting at the wheel?

fk it off and get that TZ you were talking about the other weekend

Cheers mate,

Re the aim, I'm only looking for a dash/logger set up. The Nemesis ECU and TC is very good and to go with a Motec/Marelli set up, whilst top of the line is very pricey and needs a lot of trial and error to set up correctly...
There is a small plan however to find some 1200 MTS Throttle Bodies which are DBW and shoehorn an 1299 ECU into her for full up/down auto blipping and managed engine braking.. That'll require a 1299 dash and other electronic items but not difficult. Then fit a separate logger to read the CAN from the single ECU. Given that we have access to the ECU map tables, remapping to the 1198 values would be easy

That's still happening

It'll complete the garage except for the new road bike

standard engine showed 168 on a Dynojet with poor afr and a 190/60 tyre.
We think, and based on previous builds somewhere around 182 should be possible, maybe 185.
heads will go to Chris @ CJR who did my old SPS heads. They alone made 9bhp on that bike
As she stands she's seriously quick and can kill anything off a corner. But the newer 200bhp superbikes have the legs on her once they've got a head of steam going. The standard engine is not running nicely above 9k which does hold her back.
Never want to be pinging a Duc off the limiter but she can breathe better at high rpm and be better balanced

Bookmarked, this thread needs pictures

Nice to hear you are continuing to update and change her.

That's a cracking sounding project, but that's not going to be cheap
Had you considered Carbon wheels ? I reckon they must be one of the best KG/£ reductions going ?

She's already running BST carbon front and marchesini forged ali rear....
The bike i a continuing work in progress and she was due an engine refresh anyway so it seemed rude not to.
Overall it'll be a couple of years work with me being away and all but time will fly

Sounds great, you'll have to keep the pics coming.
I run BST carbon wheels on my ZX10R, and they're night and day in terms of weight and handling effect to the standard wheels

Having followed the original build, I'm really looking forward to this!!

It can't keep the front wheel on the ground in it's current state so how on earth are you going to keep it down with even more power and less weight???

it's already a challenge!!

Which is why i'm mulling the 1299 ecu with anti wheelie mated to MTS 1200 DBW throttle bodies

[hostyle]

Now that's how to spec a bike... Great project Steve

[Steve Bass]

How she is.....



and the shexxy boxes start arriving....

[RemaL]

Steve did you say in the pat you know BSt wheels or something. just thinking the H2 could do with a set

I do mate
want me to enquire about a price???

if you would be so kind mate

Look forward to the updates Steve. Having spent a good few miles on some of the best roads in Portugal on Spareparts WSB specced 1098R, they are a bit epic.

Will you be going for the mega high comp pistons and short rebuild intervals? With Spareparts tune, the engine was super useable but punched hard as you like and revved. He ran the lower comp pistons for longevity though, but made it nice on the road rather than an animal. I think the weight wasn't far off yours either!

IIRC your frame is a 748R frame? Any beefing up to cope with extra torque/power? Got to be 30+bhp up on what Foggy's last WSB bikes were putting out!
