valve adjustment

I had today off and i decided to show my bike some love . i have about 5000 miles on her so i thought why not adjust the valves . any way i adjusted them on the loose side of spec .0025" on the intake and .004 on the ex . put the bike back together and it is making a ton of valve noise.

what is your experience with valve adj . should i have adjusted to the tight end of the spec of have a made a mistake

Your intake valves are to loose.The proper measurements are IN:0.03-0.08 mm or 0.001-0.003 in
EX:0.08-0.13mm or 0.003-0.005 in
I always adjust toward the upper end of the adjustment.
:cool:

Make sure your not mistaking "in" for "mm".
You stated that you were at .0025.Either way,if they are too noisy,you need to adjust them again.

Re: valve adjustment

just took everything off again the .0025" will fit in the back (I hope intake) but not the .003" so i know im not to loose and the .004" will fit the front but not the .005". i guess ill just adjust them all to lower end?

Blaine i think we are not on the level isnt .0025" less then .003"

Yes,your intake is at the back.Yes your measurements are correct. Sorry I was thinking .025, my math not great unless I have the gages in front of me. Maybe they just sound noisy after a good adjustment.Just recheck everything and you should be good to go.

Re: valve adjustment

I went ahead and adjusted them to the tightest spec and i am still getting alot of valve chatter even my wife says the bike sounds funny and that is a serious measure of possible weirdness

Re: valve adjustment

Did you make sure the piston is at the top of the cylinder on the compression stroke ?
