I am looking at a ty175 for my boy. The bike seems to run ok but the shifter shaft has alot of side to side movement. How big of a deal is this? Is it an easy fix? Is this a common problem with ty175's?

The tytrials kit is a good idea but ny experiance was poor as the quality of workmanship on it was terrible and I had to return it and beg many times for a refund. I then took the gearcase cover and shaft to a local machine shop and he machined out the old bushing which is cast in not a pressed in one and made a new stainless bushing that also used the shaft seal and it worked excellent and only cost me a burger and fries.
