FI or not to FI? That is the question…..

[BrettMember]

Well I reakon my next bike will be a FI husky, like it or not there is no choice learn about it and deal with it!

And mine is very likely to be a Husaberg. Bring on the FI.

A capacitor only works like a battery, it just holds charge. It will hold much less charge though. I think Bruce is right the technical boffins will likely have it under control. These would have been high on the list of design critereon I reckon.

FI should of and could of been on dirt bikes ten years ago, it is just a matter of economics for the manufactures they need to juice as much money out of technology before they introduce new ones as they spend considerable amounts of $ on R & D. We do not think twice about electric start now but 10 years ago people where uming and aring whether it would be any good or not.

More times than my insurance company was happy with!!!

A flat battery holds as much charge as a capacitor with no charge! I’d be happy if they were fitting them with kickers (somehow) but until then I’m not sold on the idea. I like the idea of tuning through a laptop tough and no jets.

Having said all that, when I owned a honda I frowned upon electric starts…then I got one.

I wonder if the same will hold true if I ever get a FI bike???

Thats so very true Shane, I teach basic electrical and heavy duty electrics and thats something we teach it wouldnt turn a starter, current would drop as fast a $2 hooker, but an ECU for the EFI wouldnt have that current draw so you could kick start it

It depends on the electrical set up, if the power to the CDI comes from the battery they will not run with a dead battery as it will take current out of the system ( most jap bikes are like this)but if the CDI runs from seperate from the battery ( i am fairly sure the KTMs are set up like this) it will still run fine with a dead battery. This is my ideas only so please correct me if i am wrong i am certianly not a mechanic i just sell the bloody things.

I think they’d need to run a fuel pump as well maybe? Sounds like I’ll be picking your brains for a few years TB!

[GregMember]

I teach diesels and electrics its sort of the same, to further Fossils last post, yes regarding the fuel pump, but a check valve would hold a head of pressure for the FI unit for very short period of time, maybe enough to start and then the alternator would supply the fuel pump yeah?

Yes i think thats how it works, all the MXers are running a kick start only and no batteries. I have read a lot of technical blurb about it but most of it went over my head.

my head hurts, ah rum, rum makes head better

Fuel injection is the best, great throttle response, never splutters anywhere and is really hard to stall if you fall off and quick to start after laying it down because it doesn’t flood.
Better fuel economy and smooth power when you want it..

Better clarify what i stated earlier,
with a capacitor they will start with a kick starter, obviously would need to be a huge capacitor to enable a starter motor, this is how i understand the MXers operate capacitor & kick and they need to be started in a hurry when they go down, look at a video of Bubba when it happens, one kick and he’s gooooone. Now as an aside isn’t it funny (not in a haha haha sorta way either) how they get all the technology first, Ala KTM all the new stuff goes on the SXs before EXCs, although Gas gas has had it for quite a while now on the 450.

I don’t think we are going to have a choice in the next couple of years even the next KLX will be FI, they already have them in Japan, maybe I can start hacking the efi chips and put my nerdy skills to good use.

Chris, we could sell OBT re-maps of all the common bike models sold. A guy on DBW already has all the software and has been playing with the Husky settings for a while now
