An interesting project but just how "completely usable" is it going
to be. Power delivery is going to be interesting and docile is not
going to be on the menu. Could prove to be a bit of a handfull in
traffic but ICBW.

Based on not looking at any diagrams I've a theory.. I don't think
you have any imobiliser, and because of this you aren't getting a +
feed to the bits that it's circuit would normally feed.

On the road bike the logic of the imobiliser will live in the ECU, the
key end of things will just send a signal to it via the 'aerial
doofer'. The fuel pump and all the imobilised things will live on
the end of a wire from the ECU, and will only get their + once the ECU
recieves it's signal from the aerial doofer..

So, as that bit of feed and logic probably doesn't live on the race
ECU at all what you may need find all the things that live on the
immobilised side of the + feed, on the regular ECU, sling that + feed
via a relay linked directly to the key.

This may of course all be wrong. Perhaps you should scan the 2 loom
diagrams.

You're ability to be wrong is well documented. But on this subject I
do know what I'm talking about.

Race engines, except perhaps in the very small classes, haven't been
firebreathing monsters for 20 years or so. Beyond a certain power
level, controllability and a linear response are usually more
important than out right power. More power is always good, but only
if the rider can use it.

I recall watching TT practise at the end of Sulby straight in about
1986. Roger Burnett coasted in for a plug chop. He was ridng the
Honda NS500 triple, the 'customer' version of the bike that Freddie
Spencer had won the world championship with in 1983. His mechanics
weren't there, so after 5 mins he bump stared it, and, when the
marshals flagged him back onto the track, rode away with no need to
slip the clutch, changing up in the middle of the rev range, and for
all the world looking and sounding like he was on a road bike.

Anyway, my bike *already* makes some 160bhp. In an entirely
predicatable and controllable way. The race engine has the same
linear response, and a very full mid-range. The difference is that it
also has some 30bhp more at the top end.

As is mine, on a regular basis :-)

You're essentially correct, although I would probably have expresse it
slightly differently. What I was calling the 'immobilizer' is
actually labelled as the 'immobilizer amplifier' which takes the
signal from the 'immobiliser antenna' (on the ignition switch), and
sends it to the ECU. There's three wires between this immob amp and
the ECU. One of them will be the 'good' signal out, saying that it's
ok for the bike to run. My initial thought, due to the fuel pump not
cycling when the kit ECU is in place, is that this wire controls the
fuel pump relay. But that's not what the diagram indicates. Krusty
reckons it feeds the kill switch, but I can't check the diagram from
here atm

>Perhaps you should scan the 2 loom diagrams.

Actually, I've got PDFs of both. What I don't have is a tool that
will allow me to cut the two pages of the wiring diagram out of the
600 pages of the manual. I guess you don't want me to send a 188MB
email?
