bike is a gsxr 1000 k1 (USD forks with worn nitride coating)

one of the legs has a "smear". I managed to twist the seal when i put it in (caught it with the slider when i reassembled and twisted the top of it over). It leaked a little more than a smear at this point. So i bought another seal and popped that in and now i have this "smear". I have done a test ride and the smear doesn't appear to have gotten worse so far. the other leg seems to be dry.

The leg had a "smear" when i checked it which is why i changed the seal, it was about the same "severity" as it is now.

i like to save rubber on the front by keeping it in the air as much as possible, this is what lead to the leak in the first place, will this smear rapidly become a gush?

the k1/k2 forks have a nitride coating that wears off where the fork moves through the seals, this was replaced on k3 and greater models. could the lack of coating be the source of the leak?

changing to k3/k4 forks requires new calipers and disks so isn't a cheap job

fwiw i had to change my seals at least twice a year, no nicks or prolonged wheelies (racebike) have been revalved. And yes the gold coating has all but gone but they leaked from new, iirc the k2 had a cpl of microns extra to stop the wear although Suzuki claim not to affect the seals on the k1s answer is to get forks re coated (not cheap) replace with 750 forks (no coating) or upgrade to newer k series.
btw, imo its not worth using after market seals they is poo and might help if you change the dust seals while you at it

thanks, i read about them upping the thickness of coating on the k2, it was quite an increase. i didn't replace the dust seals as they seemed a bit of something or nothing. i used genuine seals.

will keep an eye on it and if it leaks will give me some mental leverage to buy a newer K
