I've just completed my annual valve clearance check (47000 miles and found the exhaust valves to be at the tighter end of the specifications, at around .254mm. Clymers' spec's state the exhaust should be between .25 to .30mm, so I'm at the tighter end of the spectrum. Intake valves were all dead center of spec. at .178mm. All 4 exhaust valves came in at this tighter spec., so my question is, should I have them adjusted at the dealership now, or wait another 12000 miles and check them again? at .254, the feeler gauge slipped very easily in the gap, so they may be a bit looser than the .254, but the next gauge I have at .279 was too tight, so there has been a change from the last time, at around 25000 miles when I checked them.
It should be noted that I am competent enough to check the valves for clearance, but have doubts about my ability to remove the cams (actually, I'm pretty sure I can get everything apart, but not so sure that I can stick everything back together again, at least not without a couple of extra parts left over that I'll have no idea where they go) :-(
Also, when removing the spark plugs, I found that #2 cylinder from the back of the bike where the spark plug wire clips on to the spark plug, to have quite a bit of light white dust inside the spark plug wire, which looked like it may not have been real tight to the spark plug and got hot. I cleaned it out and replaced the plugs, but wonder if it might be time to change the plug wires. If so, on the ends that go into the (I think coil) do they just pop on or is there something else I might need to know to remove them without breaking something?
Thanks in advance for any advise. I really enjoy trying to learn about this wonderful beast and what makes her tick, but I don't wish to do more harm that good to her during my adventures through her innards.
