Currently swapping my 749s engine for a 999s engine... three questions: - anyone have a right hand spare air tube? Or set? - ECU remap and that is all I need to get it running? - three frame bolt points and drop it out? I don't need to hang the bike or take the swingarm off or anything? Seems pretty straight forward so far (and I realise I need not have done this) but on taking the air tubes out one bolt was spinning, so I tried to flex the air tube and duly snapped the corner off. Does anyone as a right hand side spare...? Getting the ECU remapped by ChrisW I assume this is all I need to do? I assume I can leave the air box where it is and just unplug electronics, clutch the various other things and drop the engine down...? I am seeing three bolts that go through the frame... I assuming if I jack-up the engine from underneath, unbolt at these points I can just drop the engine down and out.... Is this right? Any other tips?
The airbox is attached the the engine via inlet manifolds. You will need to remove it first. Unbolt all earth points and unplug all electrical connectors and undo the bolts to drop it out. Exhaust off first obviously. There is a lot of dis-assembly to do first then yes, remapped ecu, reset TPS and go.
top tip, make a wooden frame ( rather than buying the pierobon jack frame system) to support the engines you leaved it in situ the swing arm will come out on the 999 749 without having to pry the frame apart or remove the engine a la 748 etc you can then lift the bike rolling it on the front wheel away from the engine swap engine and roll the bike back...you won't get the clearance "dropping " the engine down...
I'm thinking of doing this too now, to the bike I was selling. Do you mind me asking what you paid for the 999s lump? Why did you want my bike out of interest?
just a word of caution before you go to the big engine....as it might not be as much of a real world bike as previously..
It is not road registered, track only bike - it's already out of the real world and entered into an alternate one
You don't drop the engine, you lift the frame off the engine :smile: You can maybe find a bit of useful information in my 999 engine rebuild pictures. The engine 'rollerskates' are brilliant but you can make a wooden version that does the same. I made one for my 900SS once and it worked fine. Flickr pics 999s engine rebuild br JimR
Good - the bits and pieces were from the left main bearing, brown plastic parts from the ball retainer ring and metal parts from balls or outer bearing ring. The engine has been rebuilt onto another block with bearings and has run about 1000 kms on track now and it is running real good. Jim
How do I reset the TPS? Do I need software to do this? The engine is in, no real issues except I sheared a bolt putting the air tubes on and I am waiting on a clutch tool to transfer the clutch over from my old bike. Thought I would try and start it anyway to see if everything was working... it didn't. Everything lights up, (remapped ecu in of course) I can't get neutral to show but holding the clutch in works, turns over, almost fires but then dies. I assume I need to do a TPS reset as you describe... How do I do this?
Thanks Chris, I have a mac, any OS versions? (sorry to be difficult). Thanks for the chip by the way, one question: on start-up it reads 749s, anyway to change it to 999s
If you have a mac then the easiest way is to use Guzzdiag http://www.von-der-salierburg.de/download/GuzziDiag/GuzziDiag_V0.42.app.zip It uses the same leads as JPDiag. Just set it to Breva 1200, uses same ECU. TPS reset is under the View Tab and 'Actors'.
