Hi
Being new to the Sunbeam marque, I have several basic questions to start with.
The bike is currently being re-commissioned.
Work completed by previous owner - new piston/re bore - new valve guides springs valves

1/. Expected oil pressure at the oil pressure gauge
    Cold start and running
2/. Type of engine oil (make and grade)
    Type of gearbox oil (make and grade)
    Type of primary chain case oil (make and grade)

Thanks for your input.

Regards Ian R

My solution were additional shims on the outer side adapted to the correct position with respect to the valves. I don't know if this applies to your problem, though.
I'm been in touch with chris odlin
And end float when assembled need be 0.3mm on the rocker and bush play 0.5 to 0.3mm

you asked for photos of my rocker box bushes. Here are some of them seen from the inner and outer sides. I also attach a sketch from Chris Odling.

Cheers, Thomas
Thank you Thomas

Thanks, Dani! And your tank has never been repaired, I suppose?

Hi Thomas
On my M9 the logo has a slightly different colour than the lining. I therefor suspect, the complete logo is a transfer sticker.

Hi all! Does anyone know if the logo on the tank was always a transfer or if it was hand painted in gold in the works like the lining?
Cheers, Thomas
