Foreword:
With this new development of the Assassin 2 cylinder from Driveline, Driveline goes one better! Compared to the Assassin 1 cylinders, this cylinder set now has a large intake with large Boysen ports. The cylinders also come with special forged pistons with enlarged intake windows. The port design has been fundamentally revised.
This cylinder kit can be pre-ordered from us now.

Fitting instructions:
Only to be used with a crankshaft with 10mm more stroke and 115mm connecting rod. (64mm stroke)

Options:
Alternatively, the cylinder can also be ordered with a grey cast iron liner. Bore size is then 66mm and corresponds to 397cc. A bigbore crankshaft is also required.

Cylinders can be pre-ordered now! We already have sets here, but they still need to be coated in Germany. Therefore, it will be a while before they go on sale.

The engine housing of the 31k has a narrower sealing surface under the exhaust.
