Fork seals & Oil

I purchased an 03 RC51 on Monday... I noticed the right fork is slowly leaking oil. I asked the previous owner if he's ever had the oil refreshed or seals replaced which he hasn't so I'm sure it is past due.....
Is it best to go with aftermarket or OEM seals? As far as OEM do I just need oil seals or should I replace any of the bushings or anything else?
Also, what weight of oil do these forks use?

Thanks

Never had a problem with OEM seals for replacements.
I always order a full set of bushings to go with oil seals and dust seals.
You can go with the Pro Honda Suspension Fluid SS-8, or aftermarket.
Usually in 5 or 7 wt.

Ok, thanks for the info!
I don't have any experience with the RC suspension at all.... I only weigh about 155lbs so wondering if I should go with the lighter oil?

Thanks

I would go with OEM or SKF. I have seen a few all balls and such go bad within a week. OEM come as a dust and oil seal set for about $25

I would check into the correct spring rate for your all up weight rather than worry about oil differences, especially if your fork valving is stock.

Take this advice! I just had to reinstall new OEM seals after using the ones that came with the the top out spring kit.

This is not the first time in my recollection that non-OEM seals are shit. I used 5 weight oil too and it does alright for me. Of course I change my oil with more frequency than most too.

I had those leak proof seals in my dirt bike. I used them for one ride and removed them. The friction was WAY to much.
