Yamaha RT2

[Mark Austin]

Hi lads,

I've got the RT2 finished and ready to register. I'll post some photos in the next few days.

I have a small issue. I have the ignition mounted under the tank as per a RT1, as I haven't been able to find a correct RT2 ignition and there are a couple of strange things happening. All the wiring and ignition works except for the following:

1. The ignition is on all the time. I.e. if you turn the key to off, you can still start it.
2. The tail light is always on when I turn the ignition to the middle setting.

The lights work when you turn the ignition all the way up.

Any ideas what may be wrong? I'd like to be able to turn the key off and not be able to start the bike...

Cheers,
Mark.

G'day Mark,

I am assuming the wiring connections are all correct (may pay to double check if you havn't already) and is the ignition switch in good condition or is it possible it has shorted out contacts (or is it the correct one for this model/wiring loom)?

check it out with a multimeter. also do you have a wiring diagram?

you may or may not remmber me, i met you and had a chat at CD4 in the "Corporate VIP" VIPER tent , we talked about Honda's and your smick red Guzzi.

If all is well and correct  Mark you should be able to pull out the ignition switch plug and start up the bike!!!! Yes not a real smart move Yamaha, but that is how they were. I will search out the correct RT2 switch with keys if possible for you. Tim

errrr sorta sounds right  , when you turn the key all the way lights are on,middle pos is ignition only,obviously key off pos should earth the maggy,to confirm lights on pos,you shouldn't be able to remove key from switch,(only in off pos),have a manual in shed somewhere,will check for you,cheers Mick

Hi Matchomick,

All seems OK, the ignition fits to all the correct wires and the correct colours.
The bike runs and the lights and blinkers work.
Still can't turn the ignition circuit off though.

Cheers,
Mark.

Hi Hoony,

Yep, I remember our conversation and your nice shiny red Hondas !

The mighty Guzzi was out on a run last weekend - my mate Murray on the Guzzi and me on my Bultaco Metralla. They tend to create a lot of attention those two bikes... V-Twin grunt and blue haze ring a ding.

The Guzzi got a flat and had to be taken home in the back of the ute - very undignified for the old girl.

Cheers,
Mark.

Hi Tim,

An original RT2 ignition, one on the handlebars rather than under the tank would probably solve the problem I reckon. I'd appreciate it if you could find one.
I can't believe it was a "design feature" for Yamaha to have the engine run without the key !!!@

Cheers,
Mark.

Hi lads,
I thought you may like to see the results of your advice on my RT2 - its finally finished and registered.
I now only need a few things:
1. A 360 badge for the exhaust, as my nice new one fell off on its first test ride !!!%@!!!
2. New front and rear sprockets - flat out it does 80km, and boy it it noisy with a 12T front and 49T rear sprocket. Standard is 15/39, which have been ordered.
3. Later model ignition switch.

Very sweet looking Yammie Mark. It would be a blast to ride her up and down the streets.

Excellent work, Mr Austin! 

At risk of sounding like a pedant (I'm not - it's a genuine question): Are they the right head-light mounts for this bike? I thought that only the very early AT/CT/DT/RT era bikes have the 2-piece (welded) brackets, and that the later ones had the one-piece brackets?

You thought wrong Nat......
