"La Bullet" was fitted with an indian Eureca ignition system whan I got her.
I read that some export models were fitted with that system at the factory, but I guess it was not the case for mine since I also found a used points plate in the parts box left by the PO.
The bike was starting hard and I was not confident with that system, fitted by an unknown source at an unknown date. I didn't want to stay stranded on the roadside far from home due to that box failure.
I looked for the manufacturer site and instructions, and well, it is quite laconic...
https://sites.google.com/site/kbhide4/I wrote to them to get some more info and get a price offer for a spare one, but never got an answer.
And I was even less confident when I opened the left toolbox where all the electronics has been thrown in, as if to compete with the spaghetti mix of the fork casquette...
So I decided to ged rid of the system and revert to a standard points plate.
When I dismantled the unit, I saw that it was not really in good shape. The distributor captor was peeling away and the unit looked like it had overheated (the mounter obviously didn't understand the principle of cooling fins when he decided to put it in the overpacked closed environment of the toolbox...)
After resetting the advance timing from zero, it now starts first kick and I've put 225 miles on the bike without any issue but I'm still running in the new piston, so I'll maybe still have to check my main jet choice when I can get her running faster.
(Even if the parts were still working, I decided that the 20 years old indian coil and rectifier/regulator have earned a retirement, and fitted La Bullet with a Bosch coil ref.0221119027, and a Lucas reg/rec, associated with a 6800µF/50V capacitor, following Pete Snidal advice, so to have a fully restored ignition, and the ability to start the bike with a dead battery).
