Default Stroker help

When doing the 54mm top end and 45mm crank on a zuma 50cc what do you use for a shim? I have a buddy that did the 54mm top and his piston is at top of cly with stock crank and 45mm crank is like 6 more mm. Are the stroker cranks off set for down travel?

54mm bore and 45mm crank should be perfect match for a stroker case. Have you cut the 50cc cases yet?
