Pair of VERY HIGH QUALITY off-set engine mounting cones. These are usually needed when fitting certian performance cylinder kits (such as TS1 or Casa SS200 / SS225) and the reed valve touches (or is too close to) the underside of the main frame tube.

These cones allow the engine to sit slightly lower and therefore resolves all these problems. We have had these made as most off-set cones on the market were the narrower (shallower) S1 / S2 type cones, that then cause the rubber engine mounts to collapse when the main engine bolt was tightened. Our cones are higher and are identical in height to the standard Series 3 cones - and therefore do not cause this problem.
