Fast idle / cold start mech

Yep, that looks like the jobbie that I hope I've just bought.

Discussing this with Capo, I learned that there are three different types of cold start devices on injected monsters.
The earliest has a separate cold start lever on the left handlebar.
The next has the throttle with cold start advance button.
And the latest has it all controlled by the ecu.
It would seem that you have the latter type, Drum, and our thoughts were that it would be best to look for a fault therein before bypassing the issue with one of the other systems added in.
Then again, you're probably well aware of that anyway and I guess there's no particular harm in fitting the button and it might "solve" the problem in the short term.
I dunno what sensor/s it uses but I imagine the intended benefit of the ecu controlled system is that it can vary the amount of "cold start" according to maybe ambient conditions and/or engine temp or idle speed.
I'd be inclined to look for a problem with a sensor of that ilk somewhere.
While also bidding on the button throttle if it doesn't go sky high.

Tim, the throttle tamer looks interesting.
I'll see how I get on but I might just end up with one myself.

Also, is that a Corbin seat ?
I don't remember that before.
Looks just like mine, actually.
Personally, I think the pillion scoop on the Corbin (sans cowl) really suits the lines of the monster, better than the std seat either naked or cowled.

Apologies for thread digression.
