Greetings all, I briefly floated around the forum last year while I was riding a much loved 95 Speed Triple. Then shortly after buying it the criminal elements stole it. Bike was trashed (and uninsured...) before the bloke was caught. He got 10 months and I got given the royal shaft by the courts in regards to any compensation, dont even get me started about that particular decision... there's something mighty special about "Positive Discrimination" favouring the drug addict career criminal over the honest worker. So left with a trumpy with 4 grands damage and a baaaaad attitude towards the project, but time (and drunken stays in Japan) heal all wounds. I'm back home again, the bike has been wheeled out, rewired, lubed up etc and is now running... mighty alarming firing up a trumpy thats been sitting for a while... was a definate "Was the idle always that noisy..." moment.

Now the smaller bits and peices are being tidied up, and one of those is the Tacho for the bike. Original is a goner, and finding an aftermarket one that's suitable is proving a real headache... 3 cylinder engine revving to 9,500 rpm is limiting my choices. Has anyone fitted an aftermarket to their triple?

Now all that's left is the fuel tank, ignition barrel, front brakes, panel damage, recovering the seats, replacing the indicators, respray and reregister... *sigh* Some things you do for the sake of doing them, and I'll be damned if this bike is going to the wreckers cause of a lousy thief.

Hi Dave,

I remember your story with the cops seeing your bike out the front of a place they had under survielance. Good to hear your getting back in to the S3.

Is the tacho totally stuffed? I just had mine fixed by a mob here in Sydney recently who said there is a common diode problem with them. Cost me $110. I gave up trying to find a replacment.

Stick with it mate.

Syd

send me a pm. I may be able to put you in touch with a fellow that has a tach. He had a trophy rolling frame that I bought some parts off of, the instruments (faded, scraped but supposedly working) were still there.

Syd, what are the symptoms of that diode problem?

Mick,
The tach would die, then flicker, die again, work for a little while before fading again. It was like watching a cartoon character die, it was so slow and painful.

I checked and tightened coil pick ups and all the usual fixes but no luck. Being a sealed unit I took the tach to this instrument specialist who fixed it in a couple of days. For all I know he could have just cleaned some contacts inside the unit but he said it was a common diode problem and it works fine now so I'm happy.:)

Hmmm,
Mine has this annoying habit of not working when I first start the bike - after the bike warms up a bit its fine but at first its just idle - sometimes it registers but very low again until it warms up. I was thinking a capacitor may be going in it, but this piqued my interest.

Thanks all, had one of those days where every bike I saw was a Triumph, then on the way home... well sort of on the way home, darn Vmax tend's to run wide in the corners, on this particular day it ran so wide I was about three suburbs off the direct path home and slowly trundling past the local bike wreckers ;) , I spotted a 93 Tiger sitting out the front... For a fair while I couldn't stand to be working on the bike while paying out of pocket for the damage caused by someone else. Was resulting in a lot of stripped screws and spanner chucking every time I found something else he'd ruined, but reached a point where I missed the sound of a carburetted triple on the over-run more than I was annoyed at the legal system. So it begins...

Topic on hand, is the Trophy tacho the same as the Speed? That's the problem with the Tiger's, its black faced and doesn't swing through a full arc like the Speed, would stand out like dogs balls. I'm currently at a real crossroads, I've got a bike that's running straight and sounds just right, that needs every panel resprayed and almost all the peripheral gear replaced... either I restore to original, or get the tank chromed, pull out the goggles and start getting my cafe racer on... suspect how expensive/hard it is to source an original tacho is going to be the decider!

Tacho

Yep Dave I've been down the tacho road too. I dont think they are all that complicated for a good instrument repairer. That said I finally lashed out and bought a new one - had it in 3 days through NZ importer but cost was equivalent to about $650 AUD. The tachos on the Bonneville T100s look identical just in case any are being wrecked near you. One thing to consider though is whether they will work with the 3 cylinder configuration.

Good luck - Kiwigeoff:cool:

I'm fairly sure they would as they are running off the input to one coil on both bikes, so the number of cylinders shouldn't enter into it so long as the T100 has one coil per cylinder, which I would assume it does.

Mick, AFAIK the twins use dual-output coils like the fours, not singles like the triples.
