We had a thread here a while back on modifications for open regulation KZ classes. I have a TM R2 that I drive for fun and decided to try the variable timing ignition recommend in that thread.
It didn’t come with any directions at all for installation. I have a dial indicator for the piston and researched how to install a fixed timing ignition. It’s unclear where the timing should be set for this one though. Does anyone have any experience installing these or know where to find some directions? I searched and couldn’t find much.
I’m just having a 125 Open Superkart being built for me using a new TM R2 with a variable digital ignition (and for the moment just using a stock KR KZ chassis rather than a specialised long circuit chassis such as an Anderson - that may happen later).
The engine setup also uses a 39 mm Dellorto, not the standard 30 mm. Much more fuel is pumped in this configuration (think main jet 220 or so) and the digital ignition produces a big spark to burn it.
At this stage I expect to collect it on 30 Nov (first test drive on 1 December - hope I don’t blow it up: I’ll do a separate post). I’ll send some photos of the ignition setup and once I understand the control configuration, will add some words.
