Suzuki gz 125 k6 knocking when cold / valve clearances help

[fiery tupp]

Hi im hoping for some help here please guys !
I have recently bought a 125 gz k6 with just 3k miles & supposedly serviced at 2700 miles it runs fine but is very noisy till it gets hot top end but not a tappet rattle more of a knocking & im wondering if its normal for these bikes to start up noisy or something serious ? Also I have only been able to get a haynes manual up to k5 & have noticed k1/2/& 3 have different valve clearances inlet 0.08 -0.13 mm ex 0.13 - 0.18 to k4 & k5 inlet 0.03 - 0.08 ex 0.13 - 0.18 , & I cant find out anywhere if they are different again for k6 as the makers are allways trying to baffle us by altering something to make things more awkward harder to get to or needing special tools ! any feedback would be gratefuly welcomed ......Cheers

Hi again ..I ordered a manual from motorcycle products ltd
Suzuki gz 125 / 2001 to 2007 & guess what the they have sent me the same book I already have 1982 to 2005 ( w*nkers )
so I still dont know for sure if the clearances are different after 2005 & cant find out anywhere plus it has a automatic camchain tensioner wich is not on earlier bikes & this may be at fault so if anyone knows that would be great & where I could get a manual for models after 2005 ive tried everywhere ........Thanks

can chain tensioners on suzuki are common problems

Best way was to knock the bike in high gear ie 5th and rock it back/push it backwards. Its sometimes unseizes the tensioners.

If not take off and reset, should be a how to in the haynes.

Its an automatic tensioner & not in the haynes ive got so how do you adjust these & would it be possible & better to fit a adjustable one ? cheers

Its a case of taking out, resetting it, and putting it back in.

I'll find a link somewhere to the Suzuki SV650 which uses a similar style and problem you have

I doubt very much that a manual adjuster would fit where the auto is, It's probably just a noisy engine. Like you said it quiets down after it warms up. sounds normal too me. Mine starts quiet and gets noisy after warm though it's the tappets need adjusting

Yeh thanks for the info
I took the adjuster out & its a pig to get back in without I think what must be a special tool to hold the inner screw ( or 3 hands we all wish we had sometimes ) which has just a flat screw head & winds the spring back the adjuster piston is on a ratchet so cant just be pushed in , so I wound it back with a 3inch screwdriver bit & taped it to it while I got the bugger back in , if Id had the propper manual a two minute job with an ordinary short screwdriver while adjuster still attached to cylinder , though still sounds the same ...Oh well ive done 350 miles on it new oil filters & plug , so ill just carry on I guess & keep trying to get an up to date manual ........ cheers all
