I have 2 race bikes for AHRMA; an XL175 and an XL250. I have 2 parts/practice bikes for each, 3 of which have Powroll or like kits. My mechanic said that the points/condenser kits/parts were the same for the 73-75 XL 175s & 250s. Is this so/ Why do they advertise them differently and at different prices on E-Bay, etc. Doc
