[petercooke80]

hi

can anyone help on my yamaha sr125.

i had a import wich the gears was all down now i have got the yamaha sr 125 wich i was riding the other day and for sum reason i downgeared it by mistake as i was used to goin down for the next gear i was in 3rd an droped it into second an there started a really loud sort of high pitch tappin.

the bike still runs sweet as a nut no probs there but when i throttle it the tapping is there an to ride it is absolutly gutless the flatout i can reach 40mph nothing more.


any ideas????

would be really gratefull thanks peter

Id say check your tappets, I have an sr125 and they seem to be made of cheese and flatten whenever my sons been out on it. Hes terrible for changing down like that and it flattens the inlet tappet so the valve doesnt open as far.
