Two into Three will go...

[Herbert]

Hello all.

I am wanting to replace the Li s3 150 cc standard engine from an Eibar frame with an Li s2 Italian engine (186 cc already fitted with wide-type silent blocks). When I fit the engine to the frame tighten up the bolt, there is gap between the lug of the engine casing and the engine itself, and a lateral movement of the engine approx. 3-4 mm.

I obviously need to shim the gap to eliminate the engine's movement on the bolt and was wondering how folk have gone about this. Do I fabricate a shim to-fit, or is there something else you can recommend I use, please?

Any help or guidance will be much appreciated, and thanks.
H.

Is it not an issue with the frame cones?

or the engine mounts not in far enough?

Thanks all, very helpful.

I think the issue is due to a combination of:

- one of the engine bolt tubes in the mount is protruding slightly and the mount is n't in deep enough;
-I have a BGM shock fitted without shim; and
- the cones are n't the correct ones for the wide-type blocks.

If I remember correctly the small engine mounts have flat sided cones whereas the large mounts have a chamfered edge to the cone and are slightly wider.
