Don't know if this helps you out, Daz, but I did a little google research and here are two quotes that kinda sum up the
carb vs EFI debate:
"simply put, fuel injected is harder to get more hp out of but gives better fuel economy. carburation is better for easy cheap mods and simplicity."
and
"If you are the type of person that is going to ride the bike and not try to make alot of changes to the motor (cam, exhaust, air filter, etc.) then stick with the EFI. I myself own a EFI bike and have ridden it all over the US. It performs well and does not have a problem with altitude. The computer compesates for altitude. You do not have to retune when you go to high altitudes. Remember, everytime you change somthing like above, the computer has to be reprogrammed. It doesnt know you made the changes!
Now if your the kind of guy that wants to add horsepower, change cams and make the bike a hotrod then go with the carb. Easier to work on and making jet changes are a breeze.
Yes, the carb has a computer, not like the EFI bike though. It works the advance and retard so you dont get pinging."
Whether there is an actual HP gain with EFI, I think that kind of A-B comparison need a dyno for an confirmation. I like the CV carbs on our bikes, but I would bet that the only gain with EFI would be better gas mileage and altitude compensation performance. I know that even with EFI installed stock on all Harleys now, that everyone seems to be trying to get better performance with re-mapping the EFI software...so, it makes me think, " what is the big atvantage of EFI, if you need to try to improve upon the stock setup of "best performance and gas mileage" when it's already there? Really, I think the stock CV carbs nour SM bikes are as fine as you can get, and at least you can tinker with them. The re-mapping process is very expensive with Harleys. They can have the headaches.
