Should be mine - I have a pumpkin Jeep.

TA few tweeks of the sacred screw with TPS reset each time did the trick. I had on reassembly set the butterflies to the prescribed angle as in a post in the CARC forum, by measuring the distance from the butterfly edge to the body inlet surface. I spent about an hour tweaking but got it good with a nice balanced beat from each side at 1200 rpm and nice even take up on opening the throttle slightly.
Thank you Tony for your suggestion. Might consider that over the winter. Definitely not riding this while salt on the roads!
I had the seat back today and the restorer (Damien of SeatWorks Bradford) did wonderful job at a good price.
This last week I completed the brakes. It is fun getting air from the system when the master is pumping fresh air in with each leaver pull! Anyway sorted that by cleaning out the rust and lubricating with silicone oil (a little).
The bike started after the third try. However I had a red light. I tracked it down to a broken air temp sensor wire and the heat temp sensor wire. Both were damaged and I guess the cause of the occasional red light I used to get before I started this.
After I got the engine going I proceeded to give it the initial throttle balance with a home made U tube (2 metres high with Methanol as the fluid). I use a clamp on the pvc connector tubes to dampen the vacuum pulses. The engine seemed quite good without adjustment. A few tweeks of the sacred screw with TPS reset each time did the trick.

I went for my first check ride today and did about 20 miles. The clutch is very nice now I have replaced it. No loud rattling at the moment. The engine feel really nice. She pulls well and is very smooth. I'm being careful on the revs and throttle till run in.
The front suspension seem harsh. I put a little over the prescribed 400cc per leg as I remember doing that before. It does seem very stiff and bottoms out at full extension a lot. Possibly too much air compression from increased oil volume. Will need to take the forks off and redo till it is correct.
Gear lever is too high so will move that down a spline. Everything else works a treat!. Breaks to bed in of course. It feels so nice to have my old friend back and looking so well and something to be proud of when I park up next to the young lads on there Jap bikes! Mine also has a story to tell.
Here are a few closing shots of the completed bike.

You read correctly. I turned the screw in stages in quarter turns plus and minus the starting position. Ended up one quarter turn more closed as the sweetest tick over after, tps reset each time. I expect to leave the sacred screw here. So next time i balance the throttle, will be the standard procedure.I hoped you tweaked the balance screw and not the throttle stop screw (sacred screw). Once the throttle plate angle is set the stop screw shouldn't be moved.

I rode 40 miles today and the bike seems fine. Not gone over 6k revs but seems really nice, responsive and powerful. I might try different positions of the sacred screw as it is not that sacred any more.That may not work out so well for the rest of the RPM range.
