Hahaha - I like your Grandpas story. It reminds me of a guy here... he was complaining about the transmission on his Japanese bike. I told him all he had to do was borrow a BMW for a couple days, and after that his tranny would be fine. ;)
Frankly, the transmission is exactly why I wouldn't use my '78 R100/7 as a commuter - too clunky to enjoy riding excepy on the open road. I'm on the lookout for an SV650 now.
