We didn't get SRX 400s here in the States, but I'll bet you have a burr or some other imperfection in your right fork leg that is cutting the fork seal.
Drop the lower leg (slider)and check it out.
Some automatic transmission sealer and reconditioner... about one ounce per leg... will keep the seals soft, and if it has air caps on the forks run them with about 5lbs of pressure.
If it doesnt have air caps on the fork legs, install some. Just drill and tap them for a standard air valve... it also makes fork oil changes a snap.
That should solve the problem.
