BA's BB 1700

[BlackAdder]

Umm, helloh guys I'm here again. Or well not here, cos I havn't been here before but at the previous... ...ah, you get it.

...sooo, I've got a big bore gsx as well, those who remember the topic from the previous place you know but let me recap what I've got:

K7 GSX 1700 with 12t km in the clock


Renthal bar
Brembo radial brake and clutch masters with folding short lever kit
Renthal aluminum 40 teeth rear sprocket
Robinson 17 teeth front sprocket for 30mm driven axle
BSR brake and clutch hoses
GSXR 750 -06 USD front end with B-king radial calipers
Custom ordered Traxxion front springs to accomodate the weight of the GSX
Custom made billet extenders for the gsxr USD front end for proper ride height
GSXR 1000 -07 frontwheel
Carbon fibre mudguard
Hugger
LSL GSXR 1000 -07 upper triple with risers
LED rear light
Kellerman mini-Led blinkers
OverSpeed Racing adjustable footpegs
LSL crash bobbins 
Just Bandits 35mm jack-up kit
Modified rear mudguard
Aftermarket mirrors

So thats pretty much basic stuff, nothing that special there. And then the engine:


Coerce front sprocket guard
full Yoshi drain
PC-3
Yoshimura Stage-1 cams
Re-sleeved 89mm bore cylinders by Motospeed
J.E Pistons
Carillo conrods
Machined engineblocks to take the bigger cylinder group (machining by Ape's metalworks)
Nova 30mm heavyduty driven axle from dragrace Busa parts
APE Raceparts cylinder studs and nuts
APE  Raceparts mechanical camchain tensioner
Valve head ported and measured
Motogadget RFID ignition lock
HEL oil cooler
STPS/STVA delete kit
PAIRS blocking kit

There. So thats kinda basic bigbore stuff as well I suppose... ...the whole project started because of the 2nd gear issue in the first place. I got it fixed (thats a long, sad story actually) and when I got the engine back I got some 2000 km's and it was back. So I  did what I should've done in the first place - fix it my self. I took the gears and got them race/under cutted, scored a bit heavyer driven axle and swapped them gear selector tubes to shafts.







And at that point I started thinking that now that the gearbox is bulletprooved, I just might go for a couple of ponies more. And asked where to get a big bore kit. Now the answer was 1550 at the time and there were several of them (like Maggys beastie) and I didnt want to copy what everybody else had done. So here we are now...

I've changed the electrics to k3 ones to get rid of some stuff and to simplify others. I'm still running the oem throttle bodies as I had to get the bike on the streets but thats now on the task list. The bike runs pretty darn good but I'm having issues with oil - looks like it's leaking from somewhere but it might be the breather - I have a blocking plate where the oem breather box should be and a breather hose at the oil cap. I've got a oil catch tank coming so that might solve part of the problem, other is the left side HEL oil cooler line that is for sure leaking. 

So small tinkering in sight mechanical vise, and the clocks... ...I kinda swapped my mint clocks to a crashed unit as I was to rig up motogadgets miniscope, but to be honest the GSX looks a bit empty with out the clocks casings. So I've to fix the crashed unit and maybe upgrade it a bit while I'm at it

Good to see you back onboard BlackAdder

We love pics on here

[BlackAdder]

Thanks!

I've got all of them, or most of them pictures anyways at http://addertuning.tumblr.com if someone wants to take a peek.

I've been laying low with the bikes for a while as if someone remembers my bike garage was way too far from me when I moved out of town. My own garage is still under construction (read - used as a cold storage for everything else than motors) and it took some time to find a warm garage in decent range. And as it's pretty darn cold in here during the wintertime my focus has been in four wheeled vehicles, partly because I had to (to keep them running) partly because I want my 4x4 running before next autum.

Now this bb engine build might have gotten a "bit" out of control considering that I was supposed to fix only the gearbox, but it wont happen with the truck. I'm just gonna swap the front axle and throw a locker in there. And the rear axle too. Oh yeah and couple of winches. And engine + gearbox too... ...so I've to change the electrics because of the engine and a lift kit would be nice... ...but that's it, nothing fancy...

I just love write-ups like this BA, love what you and others can do to these machines. Fantastic. 

[BlackAdder]

Thanks.

Maybe it's kind a sort of stubbornes more than what can be done - there were people stating that  1700 cant be done and it seemed to be more of a challenge at that time. ow Boris beat me to get the thing running, but maybe I'll modify this thing a bit more in the future, when everything else (the cars mostly) is sorted out.

One thing that I missed in the mods listing was the emulator circuit to get rid of the STVA error code:

And during august I managed get to the track as well, a short run but still:

I'd like to do things to my GSX14 similar to my Bandit..
BUT..It's my every day commuter bike and I know if I went down that route I wouldn't want to get it dirty..So unfortunately until I get a much bigger workshop and another GSX14 it's not going to happen

This is my rough idea of what I'd like to do....

[BlackAdder]

YESSSSS, I like that. Instapower at all time, a bit of spondo...

...you've got to Nike it!

Cool stuff in there 

Hope to see it one day,  in the flesh when mine is up and running

Wow, that's a stunning looking 14 Froudy

Ookkayy, so: got them gsxr throttlebodies fitted finally. Didnt want to run and played the c28. Aparently the modulator board I did dont work with older ecu for some reason. (I tested it with the k7 electrics, but it might be that there's just something wrong with my circuit board, not that I would admit it tho).

So this week I've been mostly fiddling ewith them darn stva's and sensors. I tried to use the gsxr actuator but that didnt work as it turns the wrong way, and its smaller - I suppose it uses different amount of current. The neat thing with it is that the stps is mounted straight to it so I mixed gsxr and gsx stva's to one that I can bolt to the throttlebodies as a dummy. But it still turned the wrong way as the sensor sees it so I flipped the power supply and ground for the sensor and the c28 was gone.

And that was good as I had booked dyno time for friday, and we are leaving on sunday for a road trip.

The dyno? Well yeahh, I was a bit nervous, and after that a bit disappointed. Now the dyno is one of the most strickt around here. Anyways the fuel pump doesnt deliver, it runs out of juice around 5500rpm (coincidently that was also the max horsepower rpm...)  and the tuner said that there's at least 20hp just missing for my setup. The figures, at the backwheel 141hp and 158Nm. Hmm yeah, that wasnt actually the final dynorun figures as we ran out of fuel.  Pretty pleased for the torque and we'll see the "real" figures after I have fixed the minor problem with the fuel delivery. And overheating issues. A small oil leak and fitted a lambda sensor threads to the exhaust.

And the c28 came back - annoying to ride. Checked all the values for the sensor, checked the stva, changed the wiring loom for the injectors and it's still there. Next thing is to check the wiring loom from the injector harness plug back to ecu. I mean, it should work...?

Cool progress report!

Nice to hear it didn't explode. 

Fuel pump issue can be fixed.


There should indeed be more horses hidden in there... Hope to be able and tell you my results in about 18 months.

... The figures, at the backwheel 141hp and 158Nm...

If I'm correct, your engine is 1691cc, which is ~20% more then stock. And your bike have 141RWHP, which is 29-34% more than my stock engine with full Akra (depending what dyno correction are used on your numbers - SAE or DIN). And you telling there is ~20HP more...

Not bad at all! Similar with stock Hayabusa with much higher torque and on a lower revs. 
Will be very interested to know, what will be the finale numbers, when you will manage the fueling.

Think you are going higher than that hp as mine 1550cc got 168hp and 160mn of torque on the rear wheel, and your one had 141cc more +bigger trottle housing, i dont remember if you changed valves coz there is the last restrition to get over. I stopt where i am at the moment, but i was very close to order the valve change to my bike  but i stop't.
I like how it is now you dont need to change down gears if you run easy and if you want to get a higher pace you just do that  .
