Need to tighten my chain on sr125 but lost as I'm new to the world of bikes. anyone dumb it down for me as google has failed me lol

Hi

Type 'motorcycle chain adjustment' into youtube and take your pick,

The SR has probably the simplest chain adjustment method on the planet - slacken off the axle nuts then turn the snail cam adjusters towards the thicker end one notch at a time each side until the chain is at the correct tension.

What are snail cams? These things:

Correct tension? When the chain is visible in the wee cutout slot in the plastic chaincase.

Then tighten up the axle nuts again & give the chain a splash of lube - job jobbed!

Exactly as KirriePete says - I have a 99 SR125 and that is exactly right - the bottom of the chain should be at the bottom of the window - just. There will be a littke space above the chain in the window. Any more help needed just send me a message. :-)

Don't forget you need to loosen the brake torque arm as well.
