I purchased a 98 1500 that ran fine on the way home. Since the bike had what I was told the original timing belts on it I felt it was time for new timing belts before I did anything else, including riding. I got online and followed a youtube video that I felt was cut and dry. I replaced the belts and the bike has not run right since. A couple side notes. Yes the Crankshaft pulleys are aligned correctly with all marks etc. I have quadruple checked. Only after pulling most of my hair out I have read a few articles where it is stated to premark with a crayon both pullies before removing the belts. I did not do this. What I really want to know is there an easy way to allign both crankshafts to the position they need to be at (TDC)? I know about adding a straw or a small dowel down the sparkplug holes but I am a bit confused by having, for better words 2 TDC's (2 belts and pulleys).
