well Diego, thanks for all the info !
So far, I have re-packed the original headset bearings and they seem to work perfectly, there was no pitting on the race thingies at all ...
I chopped and flipped the track bars and then removed the rear brake, installed only the front brake on the end of the bullhorns... then I taped it up... sorry, this is my first time ever taping up some bars and it didn't come out so good...
Also, I could not manage to pull the crank off of the middle spindle shaft thing... however, I managed to unscrew one of the sides and pull it far enough out to spray a ton of gear lube into the BB .. Hopefully that'll hold it over until I get some kind of pulling tool to remove the stock cranks...
And yes, the ratio is kind of high... 56 x 14 I think ...
=)
