I have reservations about my power valve motor - what is the easiest way to tell if it is functioning properly (can't run it on the road as it is not yet registered, so static test such as reving to 8 or 9k and see if power vale moves to open?).

You can try a couple of things:

1. IGN off >> RUN switch off >>
   Turn servo pulley to about 2/3 open
   IGN on >> RUN switch on
   
   This should cycle the RC Valve back to closed. (You may need to kick the motor over to put some life into the IGN system with this method.)
   
   Or:
   
   
2. IGN off >> RUN switch off >>
   Disconnect the T.P.S.
   IGN on >> RUN switch on (valves should cycle to "Hi")
   RUN switch off >> IGN off
   Reconnect T.P.S.
   IGN on >> RUN switch on >> (RC Valves should cycle back to "Lo")
   
   And finally (mainly for the MC16 with no T.P.S., but works on all models):
   
   
3. Run the motor. Slowly raise the RPM from idle (1200rpm) to approx 2000rpm. At this point the servo should cycle to their "Hi" (open/setting) position. As the revs pass 3000rpm the servo should close again until approx 7000rpm.

Cheers Andy. Think my servo may be knackered. Too loud to run at home at 106dB so off to Oulton or repack the pipes...

If the servo is indeed dead, pull the plug on it and pin the valves to their "set" position with a couple of split-pins. You should find that will give you a bit of middle and most of the top-end.

We had to run an Eric Gorr ported R2J like that in the States a few years ago and it was still pretty rapid on a short circuit.

Lads, just to say thanks to the folks on the forum who have helped with advice since I blew up/crashed my MC18 (notably RobH). Ran it round Oulton Park for a session last week and better than before big end went. Good news is that I now have enough parts from the the donor bike I bought to build a second one just for track days. Another winter in the shed then.
Cheers, Kieran
