This is an email I sent out to my mailing list:
Well, yesterday was about worst day ever. I'm not sure where I posted last, and I'm not updating the blog (I only have a few minutes while I wait for laundry).
My bike has been giving my problems. Over the last several days the idle has been not right. At one point the codes on the computer indicated the IAC was bad (the module that controls the idle air flow). No biggie. The bike ran mostly fine. Two evenings ago before stopping for the night the bike started running really poorly, even at speed. The idle was all over the place (high-low-high-low). We'll the group has been having a hard time putting the miles in and so we pushed forward. And I didn't want to be the one holding everyone up (mistake).
So yesterday we covered 400ish miles. The entire time my bike was fighting me. The power was surging all the time. At speed, 60+, it was manageable. At slow speeds it just plain sucked. And pulling over as many times as we do with the group, it became kinda hairy more then once. To say the least, I was in a rather pissy mood all day and didn't enjoy myself at all.
When the group finally got to a hotel here in Whitehorse (Yukon, Canada), I worked on the bike all evening and then again first thing this morning. I believe I have now found the culprit. The O2 sensor module's power supply connection was poor. The computer interprets no O2 sensor as rich, so it was trying to adjust by going way lean momentarily. When that wouldn't work it would go back to it's normal base map briefly. Hence the surging and high-low idle.
I fixed the bad connection this morning (Chuck - Remember the stupid connector that went on the fuse? Can I say I told you so? Well, it's now soldered on there). I don't have much faith in it at this point.
Also, there is VERY few gas stations with premium gas. Bruce (road captain) and I were talking this morning and we had both figured there would be a only handful of gas stations that wouldn't have premium gas. Why is this a problem you may be wondering... My engine has extremely high compression (>10.5:1), so I actually NEED premium gas. I've been adding octane booster, and at one point thought that was my problem yesterday.
So, I'll be stopping quite frequently today while on the road to check things over. I sent the group on ahead. I really wanted clean laundry and the group doesn't do well with stops. So, I'm on my own at this point. I have to make it to Tok, Alaska at some point because I had my cell phone shipped there (another stupid story). At this point I am seriously considering turning around once I get to Tok. I really am not having any fun and don't want to kill my bike just to say I made it to the Arctic Circle.
Sorry I don't have any cool pictures to share. I'm sure I took some (Buffalo in the street!). I'll keep everyone posted.
