Hmm... couldn't be much further away from me, I'm afraid!

Here's something you could try:

1. Disconnect the RC Valve servo motor from the wiring harness, and turn the pulley (by hand) so that the holes in the Valve pulleys align with the holes in the backplates. This will leave the bike rideable - not with full power, and not 100% flexible, but still rideable.

2. See how you get on with that. Then, if you still experience problems, remove the T.P.S. from the end of the spindle (being careful not to loose the little white adaptor between the T.P.S. and spindle!). Leave the T.P.S. attached to the wiring harness, but set it to approx 1/2, otherwise it can be a bitch to start!

Finally, try step 2 but with the RC Valve servo plugged back in to the harness.

Just a shot in the dark, but maybe the T.P.S. isn't working well, and is sending "spikes" to the PGM. Leaving the T.P.S. at a constant setting may show up something.
