Concerning the use of helical timing gears and Richard's initial reference to the Velocette, I merely stated that as far as I was aware most british bikes had gear driven camshafts and that Velocette were the only manufacturer (to my knowledge) using helical gears.
I have no doubt that Richard (given time) could find many other examples of non-british bikes with helical timing gears.
I can only bow to Richards vast knowledge of motorcycles which is obviously far superior to my own.
Sorry I genuinely didn't mean to offend
Just defending an earlier post I made.
