Sorry, no updates. Spoke to Al and he's trying to get to my crank this week. I need to order some gaskets and seals. After talking to Al, I probably will do some intake porting in the cases when i get it apart. I'm just confirming with him the mods to do. I don't feel like shipping my airbox and case half back and forth to CA for some quick porting. Wonder if anyone here has any good before and after pics of some mild rotary intake mods. I did find some stuff on the German scooter forum.
What I should do is pull and split the motor and order any worn parts. I hate to have the motor in pieces waiting for stuff to show though.
