Cant say I know anything about either. BRT is out of indonesia and as of a yr or two ago they dont show them for sale. I dont know a thing about the jetting unit. Webike Japan or some of the Indonesian vendors may be worth a look.
At this point ninja 250 racebikes are worth $1500 so nobody is putting $$ into them, other than 300 engine swaps. Cant be much market for ignition modules.
