Few questions?
 

I was out working on my bike and have a few questions.
First off am I missing a pin or something on my front shaft?

Secondly I was cleaning my chain and waxing it and noticed that it has way to much slack I believe. I am embarrassed to say that I have had this bike for almost 2 years and have never adjusted my chain so I figured I would ask for a few pointers. I believe I have about 1.25 inches of slack unless I am measuring this wrong.
Do I basically just loosen the axle nut and use the adjuster bolts to tighten the chain? And obviously do the same number of turns to the adjuster bolts in order to keep the wheel straight?
This is a 520 chain with -1 +2 if that matters at all.
Sorry to sound like a noob but I feel like this is some very important information that I should learn.

No, nothing is missing re: axle holes.

See Incognito's excellent tutorial - https://cbrforum.com/forum/how-mecha...et-swap-97641/. Also, just follow the procedures outlined in the factory Honda service manual for chain adjustment. The proper slack measurement is listed. There are links here on the forum for the online version that you can download.

Yes, you should absolutely learn this. Its basic maintenance that you can do yourself & keep yourself safe.

First pic...no not missing anything. The holes in the axle are for a drift/punch to run through,
allowing you to hold the axle from rotating, while tightening the axle nut on the other side.

the chain is measured for play in the bottom run. The play is measured in the center
of the run. It is the measure of movement of the chain up/down from the same side
of the chain. Either the top or the bottom. 3/4 to and 1 3/8 is typical slack for the chain.
3/4 being on the tight side. Some slack is required to allow for swingarm travel.

The adjusters look like there is plenty of travel left for adjustment/wear.

The best way to adjust the left/right on the adjusters is to sight down the chain.
It should run true and straight to the front sprocket, no 'stepping'/pointing
to one side or the other.

Hope this helps, Ern

Thanks for the reply I looked up a how to video on youtube so now just need to find the pdf I downloaded ages ago for the amount of slack needed.
Thanks for the quick response its greatly appriciated!!

And you just answered my slack question!! Thanks!!

Know what I'm doing tomorrow along with an oil change ;)

Pay attention to Gotcbr's comment, always adjust to factory spec.
My comments are just a seat of the pants, ballpark figure.
My intent is to get you down the road, short-term.
i.e. till you get the manual, as mentioned.

Good luck, Ern

Just found my manual so time to start reading.
Thanks for the help guys!!

does anyone here believe in not trusting the marks on the frame when moving the rear wheel?
you guys use a laser down the chain or a straight edge or something at the rear tire?

so.. it looks like your chain has a little bit over 1" of slack. that's fine.

After reading the manual I see I was suppose to pull the chain down and push it up which I didn't do. I just had it at rest and pushed it up so I'll have to remeasure tomorrow but it doesn't look like It'll need too much adjusting but guess I'll just wait and see.
