valve adjustment

spicciani · 03-24-2011, 06:08 PM

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.

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.

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
