Some more bottom drawer parts selection thrown on a great Yamaha bike

[Pursuvant]

I checked the chain adjusting block hash markers on my 2019 when it was new. They were off. Not by a lot, but definitely off.

Using calipers I'd check the distance from end of swingarm to chain adjust slide cover on chain side. Then use calipers to set the opposite side same distance. Then lay down behind bike, rotate wheel backwards, then visually confirm the rear sprocket and chain point directly to front sprocket.

And it would be perfect, and yet the chain adjusting covers hash marks never agreed.

Recently that fuji nut siezed on axle and cutting it off caused me to order new axle, and both chain adjusting slide covers.

Guess what, using new parts after confirming wheel alignment with calipers, the hash marks for chain adjust are still off, but only about half as bad.

Bottom line, you may want to use calipers to adjust chain & align rear wheel, and confirm with your eye looking down the chain at the rear to front sprocket. Yamaha picked the dam cheapest chain adjusting blocks in the useless parts room to throw on this fundamentally fantastic motorcycle.

It's up to us to find what needs sorted out, what Yamaha intentionally neglected, and get it done. They don't build cheap bikes, but they neglect intentionally

I thought I was going crazy the first time I adjusted my chain. The hash marks didn't line up for me either. I used calipers, too, and checked like 12 times before finally saying screw it, if the caliper measurements match that I have to be good. 

This is a pretty good tip for anyone in the same boat.

How are you confirming alignment with your calipers?

Try 12" long drill bit in Motion Pro alignment tool. Less than $10 for 1/8" or 7/64" bit.

with vernier calipers. Please accept my apology shinyribs, sorry for confusion, I should have been clear.

 

 

 

Here I'm measuring the distance (after I have set the chain tension) from the rear of swingarm to the adjusting block cover.

 

 

And here i am on the non-chain side, about to check to see if the distance is the same as what I just measured on the chain side.

 

A cheap set of manual vernier calipers can be handy, especially the way the slide sticks out the end.....

But there is one more check I never neglect. Use your eyes, after you set both sides the same measurement, and sight down that rear sprocket to see if the sprocket and chain are both aligned and pointing directly at the front sprocket.. Poor old man's approach, but it works.

Nothing to apologize for boss, I was just curious what points you were measuring between.

Never thought of that, I have calibers so I check that out to see if I'm good. I used the motion pro tool and my eyes plays tricks on me. LOL. Your way looks easier.
