Hi I'm just wondering if anyone knows the stock size rollers on the M20 is it 1/4x1/4 or 1/4x5/16 people seem to have different part numbers and different sizes for the part numbers

Hi Barrett..The clutch rollers are 1/4" x 1/4"..the big end rollers 1/4" dia. x 5/16"...Ian

Or you can fit the Harley Davidson right side main bearing rollers fitted from the forties up to 1955 which are available in standard (0.250") up to .251 in 0.0002" increments which are readily available at a reasonable price from non official Harley Dealers
