We seem to be seeing alot of members joining..or already here ?..and buying..getting thier hands on ?..lol..an atv..then they ask us..ok..i bought..begged..barrowed my buddies atv ?!..lol..and now i need to adjust the valves...because it's making a loud tapping noise !..ok..maybe even a slight ticking noise ?..lol. well..the main thing i'm seeing..is when eveyone get's done with thier valve adjusting..then they come back and say..'' hey..i adjusted my valves..and not only is it louder now '' ?..but it won't even start '' !. ok..well..this is simple folks..when you did your valve adjusting ?..and you thought you had your piston on top dead center ?..you more than likely had the piston on top dead center on the exhaust stroke !!.
and now your asking me..how do i know the difference ????..right ???..lol. simple..this is a golden rule i learned many..many moons ago !!..( and yes..if you searched alittle..this has been covered many times here ! )..when you think you have the piston on the compression stroke to set the valves ??..do this...turn the crank backwards..as your doing this..watch the intake valves...if they start to move any when you are turning the crank ?..then turn the crank back the other way...until you see the index on the flywheel line back up where you first had it..then set your valves. iffffffffff..for some reason when you start to turn the crank backwards from where you first started..and the intake valves never moves at all ??..then turn the crank back to where you first started on the index...then keep turning it all the way around..until that same index line ..lines back up inside the case and flywheel...now your piston is on TDC on the compression storke !. again..always...always turn the crank backwards from when you first start..if the intake valves start to move when you do this ?..then you had it right to begin with..just turn the crank back the other way..until your index is back on the line/marks..set your valves..button everything back up..all done !. ifffff they never move ?..then you go back to the index..keep turning..all the way around..index lines up..piston is on TDC..set the valves..button it up..all done !. added : seems I forgot how to tell you to turn the crank backwards ? ( sorry..i'm old..and thank you.. to a member here for pointing this out that I left this part out here ). if you have a pull starter rope ?, remove the pull starter rope cover, now you can use the 17mm center bolt with a 17mm ratchet and socket to turn the crank backwards .
