CDI change on a 2002 Bonnie


Hi Guys,
In my introduction post last year, I told you i was about to change the Triumph CDI for a TTP fire starter. It took longer than expected as these little things are f.. expensive but now i now it was worth it.

My Bonnie is a 790 with around 15000 miles, that I had slightly modified with Norman Hyde Toga pipes and a KN air filter after I got it in 2014.

After 3 months use od the TTP firee starter, what i can tell is:
The power losses and unexpected ignition cuts are history now.
I have gained 500 rpm.
And no problem to start the engine when it is cold. (-1°C )

Here's the link to TTP:

I will be happy to answer your questions.
