Cruise control and idle gremlins(long post)
For the record, I did search for cruise control and found several pertinent posts. Now armed with just information to be hazardous to myself and anyone else within 27 feet of me, I have a curious situation developing on my 00 LT.
First of the month, the wife and I rode 3450 miles (deliberately circuitous) to Las Vegas for a business meeting I had to attend. On the way there, the cruise started acting up a little. Mostly started disconnecting on its own. I finally figured out it was doing so on long hard uphill and downhill stretches of road. When it would disconnect, I could hit the resume switch and it would work until the next steep hill.
Now, after sitting in Vegas for 10 day without being ridden, I saddled Emil up today and headed for Zion National Park, then east over to Page, AZ where I am now. Going up I-15 from Vegas the cruise started out just fine, but by the time I got to the Virgin River Gorge, it was disconnecting more than it was staying on, and now, it is hard to get it to connect back again. By the time I got through Zion, it wouldn't hardly stay on for any length of time. I trouble shot as much as I could while riding and have found that it will disconnect when I hit rough pavement. And as anyone knows that's ridden up here, from Zion to Page, there is nothing BUT rough pavement. The red light on the handlebar stays on, so I'm getting power to it. Sometimes I can turn the power switch off and back on and it will work, but most of the time it still won't re-engage. I've tried rolling the throttle off, then WOT and back, but that doesn't help either. What I did not try today was to work the clutch and brake lever/pedal.
Thanks to this forum, I found and ran the cruise diagnostic with some varied results. The first time I tried the diagnostic, all went well until time to pull the clutch lever in. It failed at that point. I worked the clutch lever a few times, and it finally worked. So, I turned the ignition off, and restarted the diagnostic. Now, and for the last four or five times I ran the test, the throttle is what fails the test. I cannot get it to pass the closed throttle test. I have not adjusted the throttle cables so I'm not sure why, unless the switch (wherever it may be) has gone Tango Uniform.
I'm still three days away from home and I'm going from Page down to Holbrook and hitting I-40 for the long haul to Knoxville. I'm really not looking forward to three long days on the slab with manual control only. Any help or advice, or even encouragement, would be appreciated.
My second gremlin is the idle speed being very erratic. I posted a few weeks ago about my fuel vent lines not being connected right. I remedied that problem while waiting for a new J&M microphone in Lubbock. I did not find any pinched fuel vent lines, but I did find that I had the lines crossed at the connectors. After reconnecting the lines properly, the bike went for a couple of days working just fine, but then the tank stopped venting again. Also, whenever I fill the tank, (I am not "packing" it) it runs like garbage for the first 40 miles or so. It does a GREAT impression of a surging oilhead!!!! I filled it up in Vegas and rode over to the BMW shop there (Superbly wonderful folks over there by the way.) and then over to Planet Hollywood where I parked it in the parking garage. I had gone only 24 miles on that tank of gas and when I parked it and got off, I noticed that Emil was pee-ing gas out of the vent line under the topcase. It was coming out in a steady stream, but not gushing by any means. It lasted for about half a minute then quit. But for the last 1,000 miles the idle speed has been very erratic ranging from not running at all without me having to hold the throttle open and keeping the revs up to around 2K, to running itself up to about 1500. Today, with the tank nearly empty (the fuel light was on) I got off the interstate and at the three or so traffic lights I stopped at it would start out at 1500 rpm idle for nearly a minute, then drop down to under 1,000, sputter like it wanted to die, then just hunt from about 700-1200 rpm.
I'm sure I have a vacuum leak from reading the posts in the archives, but with the leaky carbon cannister, I wanted to run it by some of you with more experience on these machines than me.
By the way, the particulars are: 2000 LT, 73,000 miles and been a trouble free bike up until this trip.
I'm sorry for such a long post, but I wanted to give as much information as I could.
