72 CL175 fork springs

[ckahleer]

I got my fork seals today, so tomorrow I should be able to get the front end back together and go for a test ride.
When I dissasembled the forks, I didn't take note how the springs came out of the fork tubes.
Do the tighter coils go up or down?

Quite interesting to Google this question, to read all the different opinions on this matter.

For example, tight coils to the top to reduce unsprung weight, tight coils to bottom to displace more oil and thus affect the air gap, and so on.

In practice, I doubt that it makes any noticeable difference at all on a small elderly bike.

FSM states 'assemble the front fork spring into the fork pipe so that the end with the larger pitch is at the bottom', whatever 'larger pitch' means ....

I would assume pitch is used similarly here to the pitch of threads on a bolt or screw, i.e., the larger pitch would be coarser (fewer coils per unit length).

I guess a discussion of progressively wound springs and their action/function in suspension would be a good topic for my "classroom"......
