the very reason i binned mine, a engine designed in 40s low revving v twin
don't need the sophistication of fuel injection.
and being tied to main dealers when things go wrong???
keep things simple and user friendly
i may be old fashioned but that's the reason i ride a Harley

Love the bit about fuel being used to cool an engine - weren't Kawasaki triples petrol-cooled years ago?
Cheers,
Pete.

Close but no cigar Pete; back in my Army days I had a brief flirtation with a 750 H2, which apart from convincing me that there are
bikes which handle and stop worse than my XLCH, returned 13 miles per gallon if you were brave enough to cane it.


They weren't petrol-cooled; it was just that you couldn't afford the gas to get 'em hot!

It's such a chore, after all if I ever need to change my fuel settings I just have to plug the bike into my pc, reflash the map and put my feet up with a cup of tea I've brewed in the time taken to remap the system and then go for a ride.

Obviously I've missed out on all the fun of taking the carb to bits, putting this jet or that in, putting it all back together, running it only to have to take it to bits again, put some other jet in, put it back together, run it, only to have to take it to bits again, put some other jet in, put it back together, run it, only to have to take it to bits again, put some other jet in, put it back together, run it, only to have to take it to bits again, put some other jet in, put it back together, run it, only to have to take it to bits again, put some other jet in, put it back together, run it, only to have to take it to bits again, put some other jet in, put it back together, run it, only to have to take it to bits again, put some other jet in, put it back together, run it, coming stinking of petrol and run out of time to actually ride the bike.

I count 9 or 10 pieces of electronic junk you could take off you bike. If you stuck a carb on it.
Far less to go wrong when you are in the middle of nowhere.

Get the jetting right in a carb and you never have to touch it.

I agree
With a carb there's less to go wrong on a cold dark night in the fens and while we're at it might as well ditch the electronic ignition and fit a magneto. Then there's even less to go wrong

Given the number of different components that make up a carb, efi has a lot less parts to go wrong. Plus, thanks to SERT I can even tell what has been going on with the engine for the past hour of riding. Carbs tell you zilch, hence they require more buggering about with.
