I hesitater to start a new thread, after the 'making Bonnevilles in Thailand' one - it got quite heated at times.

Anyway - caution to the wind - according to (UK based) Bike magazine (just drpped through my door)- Triumph are having to turn to fuel injection for Bonnies in 2007 to get around new levels of EU pollution legislation. Of course we won;t know whether this is an imporvement or not until the new bikes get reviewed (my guess nearer the end of this year) - so better get buying up all those 2006 modles just in case.

In my (huge!) experience - the conversion from carburation to fuel injection usually brings less low down torque and snatchy throttle response - but Triumph's FI's of late seem to be good at getting around those issues - no-one could accuse the Speed Triple of lacking torque. So who knows? This isn't an isolated case - the article cited a number of different manufacturers and their models due either for the chop or for conversion to FI and catalytic converters. BTW It will soon be illegal in Britain and the EU to remove cats from bikes that have them fitted as standard - maybe another reason for some panic buying of this year's stock of Bonnies????

Yeah, I've heard rumours about fuel injection for a while now. There's no doubt about that it will be realized soon.
Hopefully I did the right thing, buying a new T100 two months ago.

Regardless,
new or first-time buyers of the fuel injected Bonnie will find themselves just as excited about their bikes as we have become. Besides, Triumph's fuel injection is often spoken of as one of the best most seamless fuel injection out there....

Now, if they would just give us wire wheels designed to accept tubeless tires.

<<wire wheels designed to accept tubeless tires>>

Oh - yes please! And alloy rims too? I see you can get a fat back wheel conversion in ally (5.5") in the USA - but probably not very retro!

Fuel injection on bikes has improved a bunch over tha past 20+ years. Seems funny that BMW was one of the first to use FI across an entire model line (K100 Series bikes) starting in Europe in 1983, but seems to have had the most trouble making it work seamlessly on their newer Oilhead (boxer R) bikes, due to 'surging' issues at part throttle.

Other manufacturers, including Triumph, seem to be getting their mapping right. Another mfg (Yamaha, I think) implemented some components in one of their FI systems so that it responded (felt) more like the CV carbs we have on our Bonnies.

Done right, FI may just be what the Bonneville needs. It will permit it to meet ever tightening environmental standards, and should permit Triumph engineers to tweak it so that the fuel/air mixture is correct across the entire rpm range, something we struggle to do with our carburetted machines.

We will lose flexibility in the amount of tinkering we can do with our bikes, and the aftermarket exhaust manufacturers will have to make their pipes and mufflers work with the mapping of the Triumph FI system, unless Triumph opts to use a closed loop system instead of mapped .... which is unlikely.

But I bet it'll be the end of the 'cold starting problem' threads on this forum.

I think Fat hit the nail on the head when he said they will be just as excited etc etc etc. and after a few years we will all want FI

Now, I have to ask a question.......someone posted: Oh - yes please! And alloy rims too? I see you can get a fat back wheel conversion in ally (5.5") in the USA - but probably not very retro!

My question...what is the advantage of having alloy rims? I have the stock rims on my 05 T100 and they are round and spin just fine. They look great too because of the chrome.

As i posted about a week ago, right from the mouth of a Triumph rep, the carberated twins have easily met FUTURE air standards for several years both here and in eurpoe and won't be going the EFI anytime soon.

Whether or not he's right i dunno. But i'd listed to a triumph rep before i'd believe some 3rd hand mag info.

The chromed steel stock rims tend to rust quick, and if you haven't heard, spokes are snapping on stock bonnie rims. Usually happens around 10,000 miles and has punctured tires at speed. This is happening to the left rear wheel spokes. There is a HUGE thread about this at the Delphi forums, and has been brought up here too. I'm getting new rims for my bike this winter.

It's not just Triumph, even Harley has broken spokes!

Not at all true, you can tinker with FI much more than carbs, you just need different equipment.

Put away your screwdrivers and get out your laptop. Most FI you can adjust in 500 rpm increments, and at 5% changes in throttle opening. Adjust your accelerator pump squirt, and change your ignition curve as well.

Much more than we can do now.
