or you could use the granturismo 62mm crank, fitted one to my mates rb20, didnt have to machine the case at all
How did this perform m8 with 62mm crank?
What packers where used? & what was ya mates full setup etc plz
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.

What price was the GT 62mm crank m8?
£260

hi, if using the 60/110 crank would you go for the 30mm piston?
or would you only go for the 30mm piston if using the 60/116 crank?
thanks

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
