ok, when i was checking my valves and rotating the crank with a socket and all that i noticed somthing that since then has been nagging at me. the right cylinder seemed to be pretty much completely silent in it's various compresssion and other strokes. but my left cylinder mad a hissing type air leacking noise on one of the strokes. i really wish i had had time to check it further, but not living where my bike is stored means i have very limited time to work on it.
things i should have done,
put my compression checker on each cylinder as i rotated the crank.
pulled the exhaust to make it easier to listen to the noise
really should have measured my cam chain too to see how bad it is strecthed. (really hope i don't have to replace it)
this sound was noticed with my old shims in, no new shims yet, but i don't think they were that far out of adjustment.
just curious what the pannel of experts thinks, am i being paranoid? and other than a leakdown test is there any way to check the quality of the seal my valves are making? i did a compression test a while ago (can't remember the numbers i made) but i think the cylinders were pretty even. thanks in advance, gstwin is always helpful.
What were your valve clearances? Also, you need to crank the engine with the starter to test the compression, and you'll only get an accurate reading when it's warm.
YEah don't worry about it until you can actually start the bike. It's likely a nothing...my EX does that. Her #2 is crazy silent...
and remember that hot compression is the important #
warm up the bike then do a compression test with the throttle WFO
