Chain Tension

Excuse my lack of mechanical bike knowledge, but while lubing my chain for the first time on the weekend I found there seemed to be what I would call excessive chain-play... I do just about everything there is to do mechanically to my car, myself. But my car doesn't have a chain, hell it doesn't even have pistons, so I'm stumped.

I haven't got the manual for my bike as yet, but until I do, can anyone give me some kind of hint as to how tight the chain should be? I didn't measure how much it could move, but seemed to be in the order of inches. The adjusting bolts at the back of the swing-arm are a bit over half-way out.

Any help will be appreciated... also the bike is a 95 ZZR250.
Thanks
Dave

Dave...without being technical...
3 things to remember
1st
the wheel must stay straight in the swing arm....
so make sure the the adjusters are done up the same
both sides... as you adjust the chain
and you check that with the marks on the arm...
the pointers should be the same distance from the end of the arm
and
2nd
rule of thumb...
but your chain should be adjusted, by doing up the adjusters
so that when pushed up, in the middle of the bottom run of chain
up towards the swing arm...
the TOP of the chain is no closer than 20mm
and no further than 30mm, from the bottom of the swing arm..
and 3rd...
you should NOT be able to pull any of the chain links
on the rear sprocket across the tooth gap
(that is between the teeth)
if you can , either the chain or the sprocket is stuffed


hth

cheers

Dave,

Champion bloke... And a top name to boot.


will check it first thing in the morning.

Man those kwaka manuals all look the same.

about 30mm is good slack for the chain

mate ur cars got no pistons?? is it a flintstones version??
lol.im guessing its a rotor,,and in that case it can be said it has no motor
either..cos rotors aint motors!!
