And yet another transmission clunking question!

[Joe1957]

I have a 1988 sportster that I recently purchased, and I have read all the post about how the clunk sound is normal but when I shift into forth (it’s a four speed) it makes different tone or pitch sound more of a clack than a clunk. Well that the best I can describe it, it never grinds sometimes I miss forth although I heard the clack sound but that maybe my fault for shifting like it’s made of glass. But it goes right in after that shifts into neutral no problem and all other gears. Anyone out there have any thoughts, also I just put in Bel Ray Sport seems a little better?

The 4 speed rear chain drive trannys IMO all were more noisy than the 5 speed belt drive Sportsters, The Belrae fluid is a big plus, if your tranny clicks not clunks I would ride it, also make sure your clutch is adjusted and rear and primary chain are adjusted correctly
