1931 Twin Port Model 9 Sunbeam vintage motorcycle engine kit for rebuild.

I bought this engine kit a while back as an insurance policy. I bought it as a spare but I have just sold my 1930 Model 9. So, I don’t need this engine.

What’s included?

  • Crank cases,
  • timing cover,
  • bearings,
  • cams, (one cam might have a different lift profile to the other) It’s just as I bought it.
  • cam followers,
  • barrel,
  • Twinport head,
  • valves,
  • springs,
  • flywheel with connecting rod and used piston


What you see in the pictures is what you get. The cases are grubby, but they are clearly stamped with the engine number. One of the fixings on the clutch bridge will need to be repaired. Please see the images as they are the best way to describe all of it. Or, come and inspect all of it in person. Anything that I can see is damaged has been shown in the images.

I’m slowly selling off my Sunbeam spares. Please have a look at my other parts for sale. Or ask if there’s something that you need.

International shipping available.

Condition is as shown in the pictures. One fixing damaged on the clutch bridge as shown.

Viewing: Please come and check it over before you buy. It is at PE28, near St Ives in Cambridgeshire.

Shipping: I usually ship to most destinations. If you don’t see a price, please ask. Thanks. International shipping available.

Collection: If you don’t want it shipped, I have plenty of space. If you can’t collect for a while, it’s not a problem. However, I will need to be paid very soon after the sale. Thanks.

Payment: Good old fashioned money on collection is preferred. I can accept payment through PayPal or by bank transfer as well.

Import Taxes: Please note that IMPORT DUTIES are not something I can control. If you are buying from outside the UK, there is a chance that you will have to pay import taxes. Import taxes vary from country to country. If there are charges to pay, it is the buyer’s responsibility to research the cost and pay the duties. The price that you see on my advert is for the item and not the item plus whatever taxes might be due.
