Dirrerence between air and non-air forks?

front end spring height

Hey Nessism,

I'm ressurecting this old post because spring is here and I am ready to do the mod on my 81-1100 with leading axle. In this post you recommended cutting about 3" off my stock springs. My question is, am I supposed to replace this missing height with a spacer?
Could you explain again, what advantage this will give me?

Thanks, Paul

Hey Paul,

Replace the lost height with a PVC spacer. Cutting the springs with increase the spring rate and lessen the amount of air you need in the forks.

I did this mod on an '83 750 and took off 2" to start. I think you could go up to 4 or even 5 inches without concern but start off slow - you can't put the coils back after they are cut.
