Hey gentlemen,
It's been a long time since the last update.... So here we go again.
In terms of fabrication the progress is not as good as I hoped for. But some things happened since last time. The frame is pretty much finished, I put the motor in and all fits great. Since then I started working on the EFI system.... it takes a LOT of time to choose wich one and why... so reading, reading, reading.
Finally bought the ecotrons small EFI kit. The guy was really helping me out in terms of what should be in the kit and how it all works, perfect service. Go ecotrons! Time for pictures!
Current state:
The tank is not ready yet, and I dont like the glassfiber seat, thinking of building my own aluminium one... But I'm happy with the overall looks.
Since then, EFI ;D and it really slows down progress in terms of fabrication but really cool to work on.
The kit:
One of the challenges is to get a good RPM signal out of my engine. And the old system that's on the bike isn't capable of doing that, it only has signal for ignition. So ALL the old systems have to go, carbs, ignition and electrical system. Best place for a triggerwheel / RPM sensor combination is the cilinder head in this engine. But the problem is that a camshaft only makes half the revs of a crankshaft.... and that's the problem Mr. Ecotrons solved with some software
Great!
Paper version for design check and testfitting:
And the steel one in the spare motor:
Next is software / ECU communication, works first time:
Hardware test for RPM signal and triggerwheel:
Houston we have a signal
Cover for RPM sensor:
Ajustment to the cilinder head:
And it all fits:
This is only a cilinderhead of the spare motor, but it's nice to be able to test fit some parts not damaging the original engine! Next is some more sensor integration (2 temp sensors, MAP sensor TPS sensor....) and mounting the throttle bodies on the real engine.
After the sensor integration the exhaust is next and when that is finished the engine should start or at least I can start trying to start the engine.... or so. I'm very curious how difficult it'll be to dial in such a EFI system.... we'll see. Ecotrons will support in tuning the ECU / software in combination with this motor. So I'm looking forward to it!
That's all for now. Will update faster next time.
Bet regards,
Loek
