Checking chain slack

Hi all,

When checking the slack in the chain I have about 30mm of slack when pushing up from the bottom of the chain (as per manual and posts here!).

However, I can see that the chain contacts the underside chain slider if I look further towards the front sprocket. The bike has 2500km on it and has had no chain tightening performed as yet.

Is this normal?

Pics below - you can see my finger pushing up on the chain.

Cheers,

Dave

As opposed to how far I can push it up before it can't be pushed up anymore because its too tight?

I know: I'm a noob!

When you push up on the chain, you are effectively taking the slack out of the upper run of chain, across the top of the sprockets (make sure the transmission is in neutral). So then you have all the slack in the lower run of chain, and you are able to take the measurement there. You should check drive chain slack in several locations, by rotating the chain, so you are looking for the place along the chain with the least amount of slack and then make your adjustment to the correct spec relative to the "tightest" part of the chain.

It also looks like you could drain your puke tube.

Doesn't look like there is anything in the tube to drain.

Yep, it is soooo clean and always has been :-) never a drop in it . My mates on the other hand, same km on the clock, rides with me all the time, had about 1cm of golden yellow viscous liquid in it. I assume its water/oil vapours? I drained it for him.

LOL, I pity the poor person who buys your bike .

Just cleaned (kero, toothbrush and rag) and lubed with Aufitts snake oil of choice: Maxima chain wax . As he would say: its nice golden sh1t, aye?

A whole 40 min job for a noob and two bikes!

My bad, I took the top of the insert that the cap threads onto as a meniscus of a liquid.
