So after grenading my gearbox, I’m busy rebuilding the bottom end and was contemplating whether to replace the main crank bearings. Motor only has 7000 miles on it.
Is it false economy to not replace the bearings? Both run smoothly with no perceptible play.
Out of interest, it seems like the cause of the gearbox failure was a shift fork seizing on fifth gear. Fork was badly worn radially and showed significant blueing.
I recently bought a 2003 DRZ400S and thought it would be a good idea to check the valves clearance etc . I timed the engine on TDC with the magneto mark aligned as per the manual but I find the cam timing slightly odd. The arrows pointing upward are on the 1st and 15th pin as they should but with the magneto timing mark aligned they are not perfectly straight. Same goes for the arrows that should be parallel to the cylinder head casing. Is this normal or should they be absolutely perfect ?
So I found this spring where my needle sits in the carriage. I cannot seem to find the same spring anywhere in any of the diagrams that I have seen for any of the fcr carb's. Does this even belong on my carb? Also is it oriented the right direction?
My bike was stolen, so I'm liquidating my spare parts.
I took this off my S and replaced it with an SM unit so my speed would be more accurate with the street wheel setup. I no longer need this spare. I greased it regularly and it was in good working order when I removed it. Included is only what is pictured. Cable not included.
