hi all,
when adjusting chain tension i noticed that when turning over by hand the chain tightens up slightly at a certain point/s is this acceptable or is the chain and sprockets worn? they are about two years old and nothing looks worn, have also been using top and bottom kwick slip guides,are they any good? appreciate any help
cheers!

When you say "tightens up", do you mean that the chain sort-of "sticks" to the sprockets and pulls the chain tight???????
I don't really understand your description.
A bumped thread is the best I can offer here.

Some clutch sprockets have the centre out of line, if you can try another one.

hi guys,
what i mean is the chain gets slightly more tension on it at certain points when turning over by hand.it doesn't tighten up as such as its still got plenty slack.
thanks for the input guys
cheers!

it simply means your chain has probably stretched a bit more in one place than another!
If its not severe im sure it will be ok!
As long as its not super tight then super slack you should be ok!
Is it aligned properly? Take it off and look at the condition of the links on the back of it!
If all looks ok i wouldnt worry too much

When I had big bikes they nearly all had what is called 'tight spots' in the chains. It never proved to be a problem even when running well over 100+ BHP at the rear wheel. As mentioned by others as long as it dont get bolt tight at the tight spot it should run well . The benefit of the Lambretta engine is the chain is always running through a bath of oil thus constant lubrication to prevent premature wear etc, the nearest a big bike gets to this is a Scottoiler which delivers drips of oil at the rear sprocket whilst the engine is running, this does work really well, so you can see the lubrication is great and as long as it dont get bolt tight the chain should'nt wreck itself or sprockets.
All the best
