hi guys ...need some advice

i have what sounds like a bad lifter or shim ....

just done the gap measurements and suitable replacements of shims to get clearances all sorted to roughly the same accross both the inlets path and exhaust

so about 8 thou on all the inlets ....  0.02 mm round about   and about 10 thou on all the exhausts about 0.025 mm or so

but starting the bike i still have what sounds like a clearance issue with a noticable tic at about 1700 revs ...constant .. as speed increases  not so noticeable ...or drops below there ..
on acceleration the exhaust hides the noise ...so its more noticeable on a light loading

the sound whilst riding seems to eminate from the right hand side ....or more clearly hearable from there anyhow ...but if i duck my head to the left can hear it clearly there as well

still have the head covers off... remeasuring stuff and wondering how i can clarify exactly where its comming from

first worries are ...big end wear ....or a small end in there somewheres ....

thinking i might pull a plug to help locate the issue to a specific cylinder ...but  worried its something deeper


any ideas ...?

hi charlie 
 if the sound appeared just after you did the clearences , then the fault should be there , dont you think ;-)

i hope its nothing serious  .

good luck in your search for the culprit

k-rider

the noise was there before k rider ..prompting the clearances adjustment ....

but seems to be getting worse over time ...

thanks for the encouragement

we'll get there i guess

a pull down might have to happen ....erk
