    Mountain you have no idea do ya mate
    first of all the na4900 and rna brgs have a lubrication groove and grease hole in the outer race so provideing you have a grease groove or point machined into the housing you can grease them externally.

    the problem is these linkage blocks dont have those provisions so we would have to drill precisely into where the grease groove ran and would have to do this for every bearing creating multiple grease points. i'm just gunna wait and see how long these last with reasonably regular greaseing......

    and mountain i cant buy decent na4900's for $16 let alone sell them for that much and i can buy direct out of the factory that makes the for ina and skf.........

    Why don't you just cut a channel between where the channels would lie and then you'll only the need the one nipple per bearing pair ;)

    (I'm just guessing here as I haven't actually seen the setup...)

    Yeah it doesn't matter if a bearing is made in China , Japan or in the US by NASA ... Dirt and water are the enemies ... If a bearing isn't sealed and fresh grease pumped in thru a nipple until it oozes out of the seals looking clean ... then it will wear no matter how hard the metal it's made from is ...

    Regular maintenance and/or replacement are the keys ... Expensive bearings kept spotlessly clean and greased or cheap bearings that are tossed as soon as they develop slop etc ... Take your pick ... My 1 cents worth ...

    Stoked with mine ... left it stock as a rock and ran it up n down my beach in wa for a month then dragged it back to vicco and banged bars with the cinny boys in vicco for a week .... has not missed a beat , I've got new linkage bearings but the originals are still hangin in there. All I've done so far is clean the filter.

    DIGGING the motor with the oko it loves too rev, been over the hangers and flipped it and nothing has bent
