"There's a reason every manyufacturer in the world has gone to fuel injection, and carbs have gone the way of the horse whip (i.e. still a few made for specialty applications). It's because fuel injection is better in nearly every conceivable way. Save, perhaps, for being able to poke at it with a screwdriver."
Not quite on the mark. Fuel injection isn't better in every conceivable way, its because of emissions standards. Fuel injection systems,especially those that are self adjusting due to feedback, can be tweaked to control emissions on a mass production basis better than carbs can. For vehicles that do not have to meet emissions tests, and where simpler, smaller, cheaper is still better ( snowmobiles, jet skis, motorcycles, vintage cars, etc. ) carbs still dominate. And in a lot of race applications carbs and FI compete equally.
The point is that smaller, simpler, cheaper and more reliable are real values, and they are values charished by a lot of people who own vintage cars.
So the real deal is:
If you want to modify your engine for more power you have to get rid of the DJet.
If you like playing with electronics/computers go with a modern programable system to replace the D jet electronics - the brain, wiring and sensors.
If you don't like the complications of electronics, then bolt on a set of modern
carbs like the Mikuni HSRs and benefit from 40 years of technological carb improvements.
It takes only a small fraction of the time to install a set of carbs, start up and do basic tuning as compared to the time it takes to install FI, start and do basic tuning. It took me longer to type this than it takes me to install a set of mikunis on a B20.
Maybe I'm biased, but its not because I sell and install mikunis ( I can also sell and install FI ), its because I think simpler and more reliable are very important features for a vintage car.
