anybody had any problems with the silencer hitting the brake caliper? I have a Jardine and it's been hitting fairly good. Pipe is done, I need to buy a new one but don't won't to invest and have it hit. Springs for my weight and sag is at 102-104. Seems to hit make contact on the big hits or overjumping.

No problems here, I'm using an FMF 4.1 can, I've bottomed out plenty of times.

Yosh and never hits. And the underside of my white fender has a ton of tire scuffs.

YZ sub frames often appear to be set off to one side or other when visually inspected. Check out a new unit first.
