CL 350 diff ratio

[rumax]

yes there is, but it's easier to jack up a wheel ( a rear one works better...  )and count the number of rotations of the wheel compared to the tailshaft.. and multiply by 2, as there are 2 wheels the tailshaft is turning.
For more info, use the search engine and look what has been posted before. Most have been there re diffs, as the standard ratio is crap for Australia/NZ.
