October 19, 20205 yr I have a 1976 TY175 with clutch and shifting problems. It shifts very hard: I cleaned and greased the shifter mechanism under the countershaft sprocket but it is still not the usual smooth shifting normally expected from a Yamaha. It has a hard "click" to shift. The shaft that the clutch is mounted has considerable endplay. When you push/pull on the shaft there is about .030" movement. The clutch does not have a consistent engagement/disengagement. How much endplay should I expect from a transmission shaft and could this be the problem with the stiff shifting? I am under the gun here as I plan to ride next month at the Oklahoma AHRMA event. I am thinking that whoever last worked on the bike forgot a transmission shim. I am trying to vet all ideas before splitting the cases.
October 20, 20205 yr Read this whole thread for ideas before you start. Ps. Pull the clutch actuating arm out and lube, after 445 years it needs it. https://advrider.com/f/threads/ty175-staring-down-the-rabbit-hole-need-a-guide.1463250/
