So, first time poster here. I purchased a 75-Z1 about 4 years ago for $200. It was a mess, but I wanted a mess. Now that I have wrapped up all my wife's house projects, I can spend some time getting this thing going. I can also bother you guys with lots of questions.

The first question:
I lowered by front and rear by 1-inch, and it feels much better. I have found that the chain guard is now rubbing against the rear shock and the tire. Has anyone run into this issue? Did you have to make modifications to the guard or just scrap it entirely? Thanks

A pic would help.

Did you use shock 'lowering' brackets that move the bottom shock mounts to the rear? If so, interference is probably inevitable because the geometry changes.

If you're running the OEM plastic chainguard, please don't butcher it! They're becoming difficult to find in decent condition. Find an aftermarket chainguard to cut on.

OEM shock length is 13.5". Installing shorter shocks will maintain the OEM working geometry while dropping the rear.

Good Ridin'
