« on: 24 May 2012, 08:28:13 am »
Hi guys and gals,

Cheers.

Did it yesterday, I did it so the chain was just not touching the swingarm.
Would have done it so the tightest spot was just shy of the rubber (WHEEY) but I've got a scotoiller so don't have any tight spots  8)
I should also say, this is the first time I've done it since getting the bike 2 years ago (I've checked it though!!)

No!

Top of the bottom run should just kiss the underside of the chain guide under the swingarm, tested at the tightest part of the chain, with the bike on the centrestand.

Correct spec is 40 - 50mm but this technique is a quick and easy check.

I always think, if in doubt go a touch on the slack side, chain and sprockets will potentially/theoretically  wear a tad quicker but you won't wreck your gear box or worse snap your chain.

Refer to owners manual, there should be a diagram and slack measurement.  Use a rule to check the slack at the tightest part of the chain.  Or Mikes rule is about the correct amount (you'll see if you check it with a rule)

Yes, on the Gen1 thou the chain will slap the swing arm when correct set, hence that plastic thing to protect the swing arm.

So yes I second Mike.
