Exhaust repacking

Recommended Posts

Ive been all over this and other forums and in my repair manual and cant find the answer. I have a 1996 yz125 with stock exhaust. It has never been repacked. So I was wondering after how many hours should it be repacked. Was looking into getting an FMF system but that on hold for now.

Once every 13 years is a good interval to start with.👍:worthy:

I'd say every 30-40 hours but that's my subjective opinion. Could be less on a 125 since it revs more than a 250 typically.

wow...13 years! haha.

I usually change mine when its starts spooging when it wasn't doing it before or when I lose bottom end. Bike gets raspy and noisier.

I'm sure yours is probably stuck to the silencer. Thats never fun to clean out.
