The cooling fins are original size and the original designation "CH12" is cast in.

Adjustments compared to the original:

• Generously over-milled sealing surfaces at intake and exhaust (28mm manifold can be fitted)
• Piston does not overhang
• Improved inlet seal

To avoid heat build-up, this race cylinder should be run with a 22mm exhaust (2-bend / 22mm manifold)
