Honda Shadow 750

I'm looking at upgrading from my 250cc to a 2006 Honda Shadow 750. I
don't think that year has fuel injection.

The other bike I'm looking at is a Yamaha 950 2009 with fuel
injection. Is fuel injected better?

Any comments about either of these two bikes?

 

You dont mention what model Yammy.

 

Are there many 950cc 2009 Yamahas?
I think that anyone who had advice on the model would probably know which
one (s)he's talking about.

Depends....

throttle pull is lighter.
they aren't as easily maintainable at home as they require special kit
they can make fitting aftermarket exhausts harder.
Some manufacturers and models are better than others.

If you think you might work on it yourself or put a fancy pipe on,
carbs will be less hassle.

If the rep of that instance of fuel injection is good (which I can't
help with) and there's info out there on chips for pipes (ditto) then
fuel injection is worth while.

No but you may want to consider a Harley 883, custom or std, of simular
vintage. With rubber mounting, fuel injection and comparable price and
performance to the Shadow it could be a better option.

Welcome to ausmoto! Ellen has been lurking for a while, and is a
recent and late convert to motorcycling. Hasn't mucked about though,
Ellen rode her Suzi 250 to the Penrith Ulysses AGM, from NQ, and
scored the longest distance under 250.

Goodonya and welcome aboard!

cheers, Bill

 

Hi Ellen, and welcome That's a heck of a ride - you Queenslanders like
putting in the miles! (I'm thinking here of Bill going from Townsville to
Brissie via Tarago, heh heh!)

... So it was a 249.9 Km trip ? Sorry..

 

How so? Balancing the primary throttle butterflies is the same as carbs,
and if something conks out - which should happen once every blue moon,
track it down and replace it.

Solid-state ignition doesn't need "maintenance" beyond replacing
sparkplugs. Much the same with EFI.

If the bike has a catalytic converter, as it most certainly will, what
happens down at the muffler doesn't really affect the way the bike runs.

May depend on the bike. Guzzis are senstive to TPS and the computer
and the FI are very entwined, an Axone or equiv is recommended.

Providing you don't remove that...

Okay, so I went for a spin on the Honda Shadow today and it was just
like my little suzi, only better.
So it seems it's on its way to live at my house for a while.

Those long rides are really special - once you're over the third day.

And the hospitality and friendliness amongst the biking fraternity is
absolutely marvellous.

Thanks for welcome Betty, I was thinking of looking you up while I was
down south, but we were pushed for time.
Another day.

I'm off for a ride with a great group of gals from the Tablelands and
Cairns and we are meeting in South Johnstone before heading through
Mena Creek (Paronella Park fame) and onto Silkwood and Cardwell where
we will meet some of the Townsville ladies for lunch.
Can't wait.

 

The TPS is just an off-the-shelf potentiometer. It's not something even
a mechanic would calibrate, or adjust. If the bike's running wrong,
unplug the TPS, stick a multimeter set to measure resistance across its
contacts, twist the throttle and note that the resistance base value and
gradient are withing spec, meaning your problem lies elsewhere - more
than likely in something prosaic like in a clogged fuel filter.

There isn't an efi equivalent for setting the float height or changing
emulsion tubes or other fiddly carb stuff which controls fuel delivery -
the ECU takes care of that on an injected engine. All the mechanic would
do is replace worn bits - there's no setting them up afterwards to get
them running right.

Well, you'd hope so, wouldn't you? Wouldn't be electronic fuel injection
otherwise.

If someone's going to the trouble of fitting a full system rather than
just a loud muffler, they're going to stump up for something like a
Power Commander, too.

Dunno if that's true, IK.

I think there are quite a few bikes running round with full after market
systems 'cos their owners like the extra noise and can afford the full
system, but with no attempt at remapping the fueling, by whatever means.

And not all bikes have a remap available.

This things take time...

Zebee

 

Well, I was including the Power Commander and/or other "power chips".

Are you looking for such for the Norge?

The less common the bike, or the less common modifying the bike, the
fewer options.

There are maps for the Norge, including a factory "not for
road use" one, but it isn't clear how good they are, I've had mixed
reports.

Zebee

 

Hey ? If you can buy a power commander for it then just get it dyno
tuned by a competent tuner and hey presto - custom map just for you -
those maps you refer to below had to be made by someone...

The map I had done for the Raptor was excellent

I've never seen a power commander for the Norge listed on the web sites
of those companies that sell them (locally at least).


G-S

 

Don't know if the numbers would be that huge, going on how many
secondhand bikes with slip-ons being advertised for sale list a Power
Commander as being fitted. My guess would be that bikes with ill-mapped
Power Commanders and consequent crap fuel consumption would be far more
common.

 

Well, if someone's gone out and bought an uncommon bike, they'll already
have problems sourcing used parts if they drop it or if it goes poot.
Having to dig a bit deeper to find tuning goodies is only more of the same

For the specific case of the Norge, for example, considering how much
its motor will have in common with the Sport 1200, the Griso, the Breva
1100 etc, if someone was one of the roughly eleven people worldwide
who'd insist on fitting a full aftermarket exhaust system to their
Norge, they'd probably end up having to source a set of headers someone
like Termi make for the Griso.

Ultimately, with a four-stroke, most of the breathing is done in the
cylinder head; going to a freer-flowing exhaust isn't going to make much
difference beyond reducing the amount of energy the engine has to expend
expelling its own waste products, leaving marginally more to push
against the back wheel.
