I've had the unfortunate experience of wrecking my cb1100 after only about 500 miles. Even more unfortunate was my decision to not go through insurance to fix it. I had a mechanic put it all back together for me, but it's at the point where the speedometer will not function, even though the tachometer is working fine. After about a minute of riding, the engine light comes on and the bike won't rev over 6000 RPMs. I'm assuming this is some kind of safety mode because the speedo isn't functioning. The mechanic working on it is scratching his head at this point, and when he calls Honda they won't talk to him because he's not a dealer. He does have a friend who works for Honda who told him that it has to do with the ABS, but the ABS was not damaged in the accident.
Does anyone out there have a clue as to how to get my speedometer working again which doesn't require taking the bike apart to get to the ABS, only to replace this very expensive part and find out this isn't the problem?
When I called the dealer they are hesitant to touch it because this other mechanic has already done work on it, but the mechanic I'm using owns a motorcycle shop that does mechanical work on motorcycles as their main business. They don't sell them, or sell gear for them. They fix and modify motorcycles, so I'm not sure why the dealer is so hesitant to work on my bike after another reputable shop has worked on it. Also, why will Honda talk to the dealer, but not to this other shop which is licensed to repair Honda's?
I've learned my lesson which is to always take the bike to the dealer for repair, but if anyone has any clue as to how I can move forward without spending thousands of dollars, please help!
The speedo uses the rear wheel sensor, your shop guy will need to troubleshoot the meter and the rear wheel sensor connections.
Q: When you turn on the key does the speedo needle sweep? If not start looking for bad connections at the meter.
or if possible, and you go to another dealer, don't tell them someone worked on it.

Thanks tink. I have forwarded this to my mechanic. I'll post if this leads him in the right direction or not.

Unforutnately it will be pretty obvious that someone worked on it. The bike was pretty much a wreck and while they were putting it back together I had them change some things, like a new exhaust and handlebars.
This dealer will work on it. I think they were just warning me that it may take a while for them to figure out the problem because they may have to reverse engineer what the other mechanic did. I think when he told me that he didn't realize that it wasn't just my buddy down the street working on it, but it was a reputable bike shop.
Hopefully tink's suggestion will work, or someone else will respond if it doesn't, or the dealer will be able to resolve the problem once I get it to them. The other issue is that my appointment with the dealer isn't for 2 weeks. I live in Northern Virginia and good riding weather around here is a precious commodity. Today would have been a perfect day to take her out. Bummer.

Back in January we had an unusually warm day, and I took it out. Going around a turn I lost traction because I hit the throttle too hard. I tried to get it back up, but I couldn't and I wound up going down and slamming into the curb head first. Luckily the curb was at a 45 degree angle and not 90 degrees or it would have been much worse for the bike and for me. I was just bruised, but the whole front of the bike was smashed in. I waited about 2 months before I even called to get it repaired, and now it's been about 5 weeks and it's still not done. It's rideable, but no speedo, and it won't go over 6000 RPM, so that's no fun.
The mechanic said the needle does sweep when powered up. Meter is brand new and sensor is working fine. Signal is getting into the antilock brake box. Ugh!

could it be a "limp mode" or something like that with the ECU???
Both the meter and ecu get a signal from one wire coming out of the abs unit. I think its pink and blue. If no signal or bad signal you'll go into limp mode. Check for continuity this wire.

It goes into limp mode because the speedo isn't turning. That's not the problem. The problem is why the speedo isn't turning.

The mechanic is saying this signal is good. He's baffled.
If you can get your hand on a workshop manual, it has all the wiring colours and tests you can do to get to the problem.
