sounds like you need a new chain. how old is the chain?

that's common with cag wheels & sprockets just align it as best you can & adjust the chain tension in the tight spot.

you can try removing the bolts out your rear sprocket & moving your sprocket around one bolt holes this sometimes helps / sometimes not

another thing is to inspect the clutch make sure you have not broken a clutch spring for the noise & chain getting tight

never thought of those things.... the chain is pretty much new not a single piece of rust, the person my mate got it off he hardly used it and was sitting in the shed for about 2-3 yrs so ye couldnt be a buckled wheel. i hav put tape on places looks the chain is vibration on (near footpeg, chain guard) when the motor is goin ye does nothin ill check those problems 2moro straight away i want it to sound healthy anoyys me

If it has been sitting for a few years it would be best to replace, at least then you have a good starting point and also know how the chain has been treated,and no tight spots.

try giving it a hit with wd 40 or a little oil if you haven't, already it may have a few tight links

you may have to replace the rear sprocket with a better quality one

Ozminimoto will have them in stock in different ratios or number of teeth or full kits of several sizes
