what year did Buell start using exaust valve on the xb12s? and I have been putting royal purple 20/50 in my xb12s but have not used max cycle just the standard stuff should I be worried!
Swap to Max Cycle next time. It's made for motorcycles and the extra heat from our air-cooled engines - I wouldn't chance it for the small amount of $$$ difference between regular and Max Cycle.
Hey thanks for the info I am new to Buells and just crazy about my xb12scg but have been on rice bikes for 40yrs. still would like to know what year active exhaust started on xb12 thanks redrider
