I also had that exact Triumph. Bike was a turd, so you're finally using the ITB's for a good purpose! HAHA 
One caution, I'd ditch that AEM dizzy adapter, it is not accurate enough in my opinion for what you're doing.
If it were fuel only, I'd say it'd be ok, but if full ignition control, I'd be hesitant using that.
Think gear lash and what that equates to in degrees!!!
Go with a crank trigger from GoingSuperFast. |
Thanks man, interesting on the EPM. Any more info on the issues? From what i've seen it's supposed to be more accurate than a trigger wheel setup, plus it provides a cam position signal.

Can you elaborate on why you switched from cable to a solid linkage, please?

Thanks! Honestly, the reason I went to the solid linkage is because i think it looks cool. I'm sure the cable setup would have worked fine.

The way it is now is a good balance of the injector path and airflow into the intake port.
As noted above, when i first set these up I was going to use cable linkage. The way the linkage hooks up to the ITB's is on the fuel rail side. This would have allowed the bellcrank in the middle of the engine, with the cables running under the ITB's to hook up to the ITB linkage. It could have worked the other way around, but it would have been tight. This configuration gave me a little more room with the cables to sweep around.
Also for my fuel setup I was mimicking the fuel setup from a 3.2 with the fuel rails on the outside.
