[QUOTE="Constant Mesh, post: 47897, member: 615"] Here's a good article on motorcycle transmissions. [URL="https://auto.howstuffworks.com/framed.htm?parent=sequential-gearbox.htm&url=https://www.vf750fd.com/blurbs/shifting.html"]https://auto.howstuffworks.com/framed.htm?p...s/shifting.html[/URL] The FJR transmission has three shift forks. One fork moves/positions a splined sliding gear on the input or main shaft. The other two forks move two splined sliding gears on the output or counter shaft. The three sliding gears include the engagement dogs. The FJR transmission is a constant mesh unit since each gear pair is always meshed even when the sliding gear in a set moves sideways to engage an adjacent gear. The FJR is a 5-speed so there are five sets of gears rather than the four sets shown in the drawing. The primary drive shown in the drawing is a chain. The FJR has a gear primary drive -- a gear on the crankshaft meshes with a gear on the clutch housing. Near the end of the article the author explains why preloading the shifter is a "no-no".
