Holiday Topic - Carburetor vs. Fuel Injection

[SQ4MN]

The only advantage of a carb over fuel injection is simplicity. Fuel injection requires a computer and more knowledge, skill, and tools than I have to understand it, repair it, or set it up. I believe it will give you more power and better mileage than a carb if it works right, but a carb is all mechanical and basic and works fine if you just keep it clean thats why I prefer it. Dave

I have a few thoughts/questions about this.

THOUGHT..... I sure would prefer injection on those cold NC mornings.

QUESTION.... Would all the little particulates and grit screw up FI like it does my carb?

THOUGHT..... Sure is a lot easier to deal that messed up carb than messed up injection.

QUESTION.... Is there one example out there of a V8 bike with a great running FI system?

Els,

limited to the BH range only, but i been lucky enough to ride the whole stable plus others with HiPo mods and the baddest puppy of the lot is the LS3. Its the closest thing to a ricer with a V8 and i mentioned before its not for beginners because throttling the FI is like an ON-OFF switch. Really got to be mindful of your attitude at low speeds. In some way the way the LS performs is for the next generation of extreme V8 riders...scared the shit outa me. 1/8th times would be interesting, factory says you not allowed to do 1/4's because they are too fast.

F.I. has linear acceleration. The LS 3 is strong!
But the power doesn't kick you in the ass like
a carb set-up.
When the carb's secondaries kick in, it is truly a time
for holding on.
The F.I. unit will give you better
and more consistent fuel mileage.
The LS 3 feels like it wants to pull your arms off,
but so does a carbed bike.
Shane is getting fuel mileage in the high 20's on
a regular basis.

I have had no luck at all with Fuel Injection on Boss Hoss products.
First owned a 2007 small block with throttle body injection and it
was a total joke and probably why BH did away with it.
Currently have Debs trike with the LS-2 engine and have
had problems with it Boss Hoss simply doesn't know how
to fix. For reasons nobody seems to understand the
engine just occasionally idles at 1500 rpm upon startup.
After shutting it off and restarting a couple times it usually
returns to the normal idle. I will say Rad seriously tried to
address this at Sturgis but even installing a new computer
didn't help. My gut feeling is these GM motors and EFI
are nearly flawless when used in there intended application
as most likely millions of dollars of research and developement
have been done to get everything right. I think Boss Hoss
can't afford to spend the required money on R&D to get
everything just right. Hopefully they will get the bugs out
in the future.

Ron, I wish. My latest headache with GM and F.I. is a new Silverado 2500 with a 6.0 liter Vortec. I've had it in 4 times since new (5 months) with F.I. related problems and it's still giving me problems.

Els, I have owned a new Chevy Tahoe or 2500 nearly every year for
a decade as I put on a ton of miles in my business. No fuel injection
problems ever. Maybe you should quit getting wasted and pissing
in your gas tank.

I sure wish it were that simple. I've had some hairy moments with it pulling out into fast moving traffic and even worse, it crapping out as I'm feathering the accelerator trying to get up our mountain...with ice all over the road. It's been a real bastard.

I of course have had suggestions from Neil and David. Both have the same remedy...go back to an F350 Ford.
