Greetings!
So, I changed out my spark plugs Bosch X5DC to Bosch X5DC last Saturday, and all seemed well: Fired up the engine and it sounded normal under stationary revving. Tried to meet my club for a ride the next morning, but had enough stumbling/halting issues under acceleration that I turned around and came home. No, I did not do a test ride post-maintenance, unfortunately, so I did not catch that issue earlier. :-/ The following are some notes regarding my thoughts on this issue.
Note 1: I did attempt to modify the gap on one plug, #1 cylinder: Did I damage it inadvertently? I used the coin-type gap tool I already had.
Note 2: I did -not- have my m/c cover on my bike during the rain late last week: The car port where I store my bike is open on two sides and it might have gotten wet while I was at work. Should I be thinking water in the gas tank, or stick with the plugs as the possible issue?
Note 3: I tightened the plugs down finger-tight, then gave a 1/4 turn with the plug tool. I tried to use my Pittsburgh PRO (Harbor Freight) inch-pound torque wrench, but I could not hear/feel the "click" like with my Kobalt (Lowe's) brand foot-pound torque wrench, so I backed it off and stuck with a 1/4 turn. Also, I did use copper anti-seize on the plug threads.
I am going to try swapping in the old spark plugs and see if that changes anything. If it does, then I assume it is plug related. If the issue persists, then I do have Iso-Heet on-hand to try if anyone thinks this might be water-in-the-tank related. I am concerned it might be an air leak in the system somewhere as mentioned in at least one other thread I was reading here in the forums (http://forums.bmwmoa.org/showthread...ut-am-I-looking-at-breather-issues-or-bad-HES)
Please offer any feedback. I look forward to hearing (reading) from you.
