Huh, who da thunk it! I managed to get my friend who has been a mechanic for over 25 years, worked on Yamaha's most of his time at it, and also raced against CanadianFJR. Unfortunately he no longer works locally. He happened to be home from the oil fields in western Canada and was willing to look at my bike for me. When I pulled in the driveway he said my bike sounded like it was running rough. He reached under and proceeded to gingerly touch each header pipe. He then gave the throttle a couple of cracks and said the tach was off. In a matter of seconds he looked at me and said #4 cylinder is not working, probably due to the plug. We torn it apart, he checked the old plug and it wasn't firing properly at all. He happened to have a proper plug put it in started the bike up and she ran like a champ. I asked him why plugs with only 7000kms on them would fail like that and he said sometimes after winter storage it does happen for whatever reason. He told me to change all 4 plugs just to be on the safe side and not to bother with a TBS. I left and I have to say the bike was like night and day. It pulls like the freight train it was last year, :yahoo: and no more Vespa-like power. Note to self, "KEEP AN EYE ON THE PLUGS!" no matter what milage they have on them. If the bike is sluggish that may be a factor as it was in my case. Best of all it cost me a case of suds. Yes he is a ggod friend. BTW Scott, (CanadianFJR), Bill and Mary Beth both say hi.
