im just trying to remember now, i think it had a thick head gasket as the piston would have pretruded out of the barrel, i think standard base gasket was used, rayspeed can give you the full spec, exhaust port was enlarged slightly as was bottom of inlet port, rayspeed added the longer rod 116 and sold my pal the barrel and piston and head gasket/ packer, and mammoth head, he hasnt had it running yet as the scooter is not finished yet, he has been waiting for a new cursor for his close5 gearbox, he is going for that tomorrow.Norrie Bodge wrote: ↑Thu Aug 16, 2018 2:58 pmHow did this perform m8 with 62mm crank?

The measurement needed to make on lambretta barrels is 146mm as standard crank at 58x107 × 39 height piston is 146mm 60x110 x39 is 149mm add 3mm packer and back to 146mm and 60x116 plus 30mm height piston is 146mm and set all up to suit port timing
