Thanks for the reply.On the labor side of things....is it a press fit? So would it be a case of heating the crank flywheel and freezing the new gear shaft?Thanks.
Just out of curiosity, isn't there something that times that shaft to the crank throw?Seems like it is driving the cams and the ignition so there must be some sort of positive anti-rotation in there?
Tremendous advice gentlemen, I appreciate it.Just as a background on the said engine.rebuild following a cracked crankcase, new top end and rebore.Crank/big end was good. Rebuilt using genuine RE gasket set.Oil pump checked out good and motor turned at every step to ensure nothing was unduely tight.Ace- would a genuine gasket set not have the correct thickness gasket?Is there anything else I should look for that could have led to this?Also, when the bike was together before the crankshaft break, I did try firing it up...it span the motor great but would not fire, I checked the spark which was great and also the timing of the spark which was slightly off.....there isn't a way of timing the distributor up wrong regarding the drive to it is there?Also the plug was wet but still no fire up???
