I found a few sparkly bits on my tranny magnetic drain bolt and have pulled the tranny apart for repair. I found some pitting on the 5th gear. The mating 5th gear on the lay shaft appears to be good. Bike is an 81 RS. 33/11 So my plans are to replace all bearings and maybe some other 'bits' As I also need to replace 5th, I'm wondering whether to put the taller gear in. There have been plenty of times when touring that I've thought it would be nice to have the slight reduction in rpm associated with the taller gear. Anyone got some first hand advice on what to expect re rpm or other issues? I tried to search for info but had no luck. Thanks in advance.
