mcman56 Posted November 10, 2021 Report Share Posted November 10, 2021 The ball plunger/ spring mechanism on my TY175 kick starter is not doing a great job of keeping the kick starter rotated in out of the way when riding. I tried a stronger spring but it is still not great. Is there a way to improve that function? I wonder about deepening the hole that the ball drops into when rotated in but don't know if that would help or make it worse. The fit of the kick-start lever to the shaft it rotates on is not like new but not bad for an old bike. I had a similar issue with a TLR200 but never came up with a good fix.

feetupfun Posted November 11, 2021 Report Share Posted November 11, 2021 (edited) I've got more life out of TY175 and TY250 kickstarts by fitting a screw into the lever to adjust the preload on the spring. M6 x 1.0mm screw - drill and tap job. The problem is partly because the pivot wears which reduces the spring force on the ball. It is also because a groove forms which lets the ball climb out of the hole easier. You can fill the groove if that is an issue.
