Greetings Riders!

Well today (after much procrastination) I changed the speed sensor.

The speedo had been spasmodic and could not make up it's mind if it was going to work or not. After searching this forum, I found that the speed sensor was the culprit.

So checked the service manual - it looked really simple. My concern was whether there was oil going to come rushing out when I pulled out the sensor as it is at the back of the engine. It said nothing about it in the manual so it should be cool.

Went out to the bike with my new sensor and a sense of excitement. The first problem was the diagram in the manual was on an engineblock that was not mounted in a bike. The reality is a little different!!! It was a little tricky to get to the bolts that held it on and I also had to take off a big chunk of the tupperware - ah well - thats how it goes.

So finally got to the bolts and went to pull out the sensor and oil started coming out. Bugger!! Lucky it was on the side stand so it was a little elevated (as the hole the sensor goes in is on the right side of the engine). Using some of the sleight of hand skills developed as a con man in the late eighties, I swiftly pulled the old one out and the new one in with minimal oil leakage. Then I noticed the rubber seal on the old one that had to be put on the new one.

Arrrgh!!

So another sleight of hand trick and a bit more oil on the now protected garage floor and it was in. Access to tighten the bolts was again "interesting" to say the least. Everything was all tightened. Stood the bike on the centre stand and added a bit of oil to account for that which had leaked out. Quick bit of plastic surgery to put the plastics back on and she was ready to go.

I don't know about you but whenever I do something on the bike and get ready to test it, i have this little thought "what happens if it doesn't work". To which the answer is usually "take it to the Honda dealer!"
This thought was going through my head as I rolled the bike out of the garage. I gave it a little surge forward and the speedo needle didn't work. Not feeling too good!!!

Backed completely out on the road, then with a "here we go" gave it a big burst of throttle. The speedo kicked into life and all was good. A nice long "Yehaaaa" from me and a quick thanks to the Honda Gods and all is well.

So much so that later tonight I went for a quick hour long ride on the freeway just to check it was good. And it is!!

In summary, it is a pretty easy change but do expect some oil spill and you will have to take the right plastics off to do it.

For photo's refer to the service manual as the motorbike gets in the road of taking any accurate photos!!

And as an FYI on how far the bike has travelled for the sensor to die, it is a 2002 ST1300 and it has done about 41,000 km (I think thats 25,000 miles)

Enjoy!

congrats on the speed sensor change. i wonder if there is a different part number for a police model sensor that would cure the incorrect mph on the non-police model!!
 
Everyone has to be baptized with oil when the garage floor is unprotected at least once.

You have a 2002 ST?
Wasn't there a big recall for oil pan and frame braces on the 2002. ST1300 were never offered in North America until 2003.

Just to be clear, it is not that the speedo was inaccurate (although it was), the problem was the lazy needle would not move off the 0 figure!! After about 20km of riding or 15 mins it would then work - but it could (if it wanted to) stop working again!!

This is what a dealer (who I didn't buy the bike from) told me. About 15 2002 ST1300's were sent to Australia by mistake. They have no ABS and a manual screen - two positions up and down! About 4 of these got "lost" in the warehouse. It works out that my bike was one of these. It was first registered in early 2004. The second owner of the bike (and the guy I bought it off) worked at Honda. Honda asked him would he mind if they did a few things to it. Naturally he said no.

So they retro fitted the electric screen, a Honda Radio and tweaked with the "MAPS". I am not a big techo but apparently tweaking the MAPS gives it more oomf etc etc. All I know is that it gets up to speed very quickly!!

This means I have a very rare 2002 ST1300.

hey wgm

sorry for just thinking out loud about the police speed sensor etc. glad you got your problem fixed!!
 
I'm just guessing that you tried the hammer on the speedometer and sensor first? Please tell me you did...

Don't be sorry!! Thinking out loud has produced some of the funniest moments in my life. I wasn't sure if you were having a laugh or not so thought I would be clear.

It was a small hammer as it was hard to get in behind the little bugger!!
As expected, couldn't fix it. Must be electrical. :crackup

In all honesty - when it first started happening I did give the speedo a couple of delicate taps, then a firmer nudge with a clenched fist. Didn't fix it though!!

It is much better to know the speed when I ride now. Specially since there are a lot of reduced speed freeways near me due to road works and the police are doing a blitz on people going over the roadwork speed limit - They impounded 2 semi's last week under new hoon laws as the limit was 40km/h and the trucks were going about 70km/h - even though it was at night and no one was working there!!

I know, it's an old thread, but i am facing the same sensor change.

I wonder how long the wire of the speed sensor (9) is. On the image below it's quite short, but i'd like to know if that is realistic.
