    Ahhh...entonces entendes la combinacion de colores y el Tribal del Toro en el tanque, no?:evil

    The Mini Dakar is simple.
    Ship the bikes to jujuy, take a plane to jujuy, pick up the bike in Jujuy, hit the road straight north.
    Hit bolivia, Salar de Uyuni (spend a Camp night there) , go to La PAz, ride the DEATH ROAD (LA ruta de la muerte) , then north to Peru Through the Mountains, to Cuzco (several nice sightseing parts in the middle), Matchu Pichu, keep north until we touch NAzca,
    Change course to the West, once we see the Pacific, change the course to South East, cross country, Chewing Coca, until we reach Salta.

    Thats it.:lol3
    im afraid I havent more details, Im not the navigator, Im the "Trash bike" (the last one in the line, who has the mechanical skils and is fast enough to catch the first one if necesary).

    Sorry....I've been very busy riding!!!

    Regarding the roller bearings, the installation requires an inner steel race, because the Camshaft is cast iron (yeap...with thermic and chemical treatment, but cast iron).

    So , for the External rollers (or the one that are at the extremes) I can machine the camshaft and install inner steel races (something I will not like to do, because you make the body weaker)....but the real problem is the one at the middle...you simply cannot install an Inner Race, so again, you will need a split inner race in order to Install a split cage bearing, and then a split outer race....

    Although is technically possible, that is really a mess...(my engineer logic tells me "perfect technical solution in order to reduce friction, drag, etc , but by mechanic soul tells me "keep the damm thing simple" ) ....SO... I the best "mechanical solution will be ....machining a steel CAmshaft.....and if you machine a camshaft , you can make it in order to avoid using split bearings....

    That's it...
    What I did right now is to repair the complete head , new material added to the Camshaft, new lining of the lobes, new chemical and thermal treatment...And I have a new Engine....
