520 chain

[454MRW]

You would be surprised that even Honda dealerships that service new bikes don't adjust the chain correctly. For example, when we had a new CRF150R, it called for a minimum of 1-3/8" play and when we got the bike back from a recall on the swingarm replacement it was adjusted far too tightly, which could have resulted in a broken rear engine case due to binding the rear output shaft if we had jumped the bike. This was a common occurance on the CR125R and 250's. It is a good habit to get into of checking the chain tension through the swingarm travel with the shocks removed and positioned parallel to lining up the countershaft, swingarm pivot, and rear axle. Once you determine the tightest point, then you can adjust the free play of the chain accordingly, and never have to worry about it being too tight. It could save you a lot of grief and $$$. Mike

I made a simple adjustable arm (metal rod) that goes on the swingarm / or rear axle, and up the rear frame loop. It holds the compressed rear down in the proper postion to adjust the chain correctly. I can take a picture of it, if you'd like to see. As soon as I replace my broken camera.

You can take a pic with your phone, and send it to your email address on your computer. Mike

Dual headlights - 70 Chevelle and it's a Super Sport.

OK, so forget about the Chevelle.
Who is in the photo, and what is he riding?
Great way to segway from a discussion about chain tension, to an iconic photo.
