My main bearings

[KicksonR66]

So my mains are toast and was reading this thread http://www.gasgasrider.org/forum/showthread.php?t=12276 for part numbers.
I have an 02 XC300, would these be the ones I need as well?

Thanks and Cheers

Yes, those listed by the last post. They have been OEM from '02 to '07.

Thank you Sir.
Questions: Can I use the C part number at a quality bearing manufacture source?
I'm in the US, can anyone refer me to a good one?

Thanks

I use these guys:

They have been great and are very knowledgable, used to supply GGNA and Ty Davis's team. The "C" is the clearance spec, which is always C3 or C4 for a main bering in a two stroke application. C3 is good. You could actually go different ways with this: the OEM parts, the newer sealed ball bearing replacements, or heavy duty M series open ball bearings. Worldwide is doing a lot of ceramic stuff now too. See what they say, but OEM is fine. I'm not sold on the sealed ball bearing idea yet.
