Hello friend!
Welcome to this forum! You´ll find many technical hints and tips concerning the 500cc-EFI-unit used in the Classic- and Electra-frame. You´d be the first to join the board with the 350! This nice bike, that is much closer to the old pre-unit-Bullet, is unfortunatlely not available in the export markets. That´s a pity, because it probably has many qualities, that could satisfy many potential riders, combined with a significant price advantage over the 500.
So I´m afraid you won´t get any specific tips for the 350, most of the model´s details are unknown to most of us. Maybe an Indian forum could help you better, unfortunaltely I have no links for you. Maybe one of the fellow riders on this forum can post some.
I´d like to hear about the behavior of the little one, though, maybe they´ll show up at the European or the American makets in the future. So please keep us posted. To boost your anticipation I´d like to add that the unit models are running surprisigly reliable, no comparison to the pre-units!
I hope you will have as little problems as I had with my precious - ride safe!
