Im having spark plug clearance problems, with park plug and cap on, im just about 2-3/16th too tall, which resulted in a busted cap and bent spark plug. I will be replacing them, and im wondering if they make really short spark plugs for motorized bikes? Also do you think i could sort of lean the motor a little to the left or right to give clearance to a normal size spark plug without effecting the chain to the sprocket. Ive included two pictures of what im working with. The bike ran awesome until the spark plug cover and plug broke.
