diffreent spur cb combo effect shift oints?

[maximusraylius]

i was wondering if i need to adjust my 2 speed trans after i put different gears on my 25 . it don't want to shift into second and sometimes it seems to shift way to soon and bogs it down till it builds up speed. any help will be great thx everyone..

max, lets start off with the gearing numbers before & after you changed.


but yes, it will effect shift point. changing to different diameter tires will affect shift points also

i started out with a 49 spur and a 15 cb. burnt up the 49 spur and only had a 47 spur top put on it. so now its running a 47 spur with a 15cb. haven't changed the tires on this one. thx for the help.
