opinion on bottom end bearings and seals

[BobbyZ]

I'm redoing my old 93 e series from the bottom up and figured I'd ask for your thoughts on aftermarket bearings and seals.Is it ok to use them or should I just stick with oem?I'm not really concerned about the money aspect as I'm more or less concerned with the quality as I'd hate to have to reopen the bottom end anytime soon.Oh and if it matters its far from stock,it has a old frp port job,2mm over reeds and a pipe.........and thanks to this place she is also getting a RB high cr head and carb

Thanks again guys

I just replaced all the bearings and seals on my '92

I have a friend that used to work for Mcguire Bearings, he gets them at cost

We replaced all, the bearings and seals for under $50 except for the input shaft needle bearing, it's a Kawi only part

buy OEM or good aftermarket seals, and have the bearings matched up at NAPA or your local buddy who has a shop if you are lucky enough to have one of those friends! You can get higher quality bearings cheaper that way, If not, aftermarket are usually fine, although some may be cheap chinese crap, and OEM are definitely fine.

Might as well replace every bearing you can find while you're at it. Sucks to have to tear down in a few months after a rebuild for some tranny bearing you never thought about when doing the bottom end. Some of the needle bearings you're better off just forking over for OEM, as they can be pretty hard to match up.

BTW I was told the mark up on bearings is 400%

If it were me, I'd just go with OEM.

I'm with Mr. Wibbens, I go to my local bearing supply house to get all my bearings for all my bikes and projects. I don't get a discount but I go to the same guy every time because he know's I want a quality bearing.
