Don't know whether the engine feels good in this frame, but I think it's a nice combination.   It's a 750 W SP frame and 1127 lump. Not really easy to get it in, surgery by angle grinder sorted it.  Kept the rear lower engine mount. Upper one doesn't work. Will have to machine new front mounts and new ones for the frame rails. Everything's close-fitting, but it works! Will keep original swingarm, rims and fork, but it'll get EFI.   I have a cunning plan! |

Should be a good project. I always liked the look of the water cooled 750 & 1100, a bit sharper than the late oil cooled. Starting with a SP is a good move.

Just today I told my friend that one of the most pleasing bike that I have had was 1994 750w with 1127 in it. It was so much fun and quite good on the twisties. And the wheelies  |

Me likey! What stuff you using for EFi?

I'm actually after the parts, that I need for the rollin chassis and for getting the engine in the right position (chain alignment).
Will use GSXR1000K1 throttle bodies and ECU from GSXR1000K8 with the ECU-Editor. Fuel pump (external) is out of the early Hayabusa.

superbe projet
la pose de l injection se fait bien sur ces moteurs? on en vois de plus en plus mais ca doit etre un sacre travail
je vais suivre ca

Though I haven't tried GSXR1000 with the EcuEditor but I guess it's pretty similar to gen2 Busa. It's really nice and versatile tool if you are tuning a relatively stock bike but it has certain limitations. So further you go from the stock configuration more compromises and workarounds you have to do. Sure you can make it work (somehow) but I'm not sure if it is worth of effort as there are more suitable aftermarket ECUs available. |

Thanks arttu, hope that your fears aren’t that critical.
That’s the parts I still have, so they’ll be the first choice. Bits have been cheap, so no prob at the end to throw them away, if they doesn’t work.

I had a play with a mates B King with ecu editor and was pretty impressed. Complete access to all fuel maps, ignition, powervalve, etc.Datalogging and auto tuning off logs as well.
I think the biggest issue with this is having to exactly replicate the gsxr crank and cam triggers so the ecu still thinks it's on a 1000. It's doable but a fare amount of research and accurate engineering required where as with an aftermarket ecu, fuel only, you could just use the stock ignition and so the only tricky job is getting the fuel in out of the tank. Or with a simple 36-1 trigger wheel, you could have spark as well, using the original crank sensor. But it's your project and I keen to see your solutions :-D

But it has some limitations for major modifications like fitting the ECU on another engine. Like: -No calibration for different sensors (except MAP), you must use original sensors or something compatible. -No access to injector parameters like opening/dead time, even injector size change must be compensated by fuel tables. -No warmup and acceleration enrichment tuning. -Crank and cam sensor setup is fixed. Some of these can be fixed with various workarounds and some may not cause major troubles if you are lucky. But it will take some serious work and even then the result might be a compromise. But if you already have the parts and you like challenges then why not  |

Getting the right sensors wouldn't be that critical. Injector parameters wouldn't be that critical either, but if warmup and acceleration enrichment tuning is missing, would be not easy to get it working. Will try to get engine mounts done the next week. Than I'll have to look after the exhaust. After that EFI will be the next challenge. Hope that I can get some help here, from the guys, that already played with them things.  |
