[QUOTE="jaguar, post: 660791, member: 19340"] I thought I was using a good method of front/rear sprocket alignment by using a tape measure to get equidistant the right/left side of rear axle from the swingarm pipvot bolt. BUT when I double tested the results with a pen laser light I found out the light beam (aligned with rear sprocket) was pointing about 7mm to the left of the front sprocket! So then I adjusted them accordingly. I expect much longer chain life now. HOW I DID IT: I cut off the top of a quart sized clear plastic water bottle where the neck meets the body. I put that (bottom end down) on the top of the rear sprocket and (in dim lighting) shone the red laser light through the bottle top in alignment with the rear sprocket (by keenly eying it). The light leaves a pinpoint reflection where it goes thru the plastic. Then of course I was able to see the dot of light to the left of the front sprocket (whereas it should of been shining on the front sprocket). I bought the pen laser here for $2 but I think Radio Shack sells them in the states for $20. Let me know if you try it and what results you get. [/QUOTE]
