Hello All ,

Can somebody please give me some advice !.

just about to rebuild the engine on a restored LI 150 special been offered a new MEC GP road race crankshaft , brand new off of a mate.Got a static electronic kit for a GP taper already working on the engine going to try and use 26mm carb' with remote filter. Cylinder wise i bought a new V4 mugello 186 kit a few months back, i have spoken with a couple of dealers who stock this and are saying i can use the 60mm stroke x 107mm conrod crankshaft as long as i use a 1mm packing plate at the base of the cylinder does anybody know do i need to change the cylinder head ? the one i have came with the kit with the 3 additional location studs i dont know if i am getting confused with 192cc kit set up , or would i be better off waiting and getting a 58mm stroke x 107mm conrod.

Any help would be greatly appreciated.
