as a recent vanvan 200 owner I've been looking at parts and pieces and I priced the FI throttle body, FI control unit and the complete wiring harness for the RV200 (vanvan) at aprx $1000 not cheap but as time goes one some vanvan's are bound to be parted out and those parts becoming available. If someone could possibly sort through the harness and separate the FI essentials and assuming the thoittle body will physically fit the TW (I'll research this more soon) we might have a viable FI solution for the TW

Of course right about the time we do this Yamaha might start offering that upgrade on the TW

I mean if they were to do one single thing to improve the TW w/ destrying the classic cult bike we all know and love a TBI FI upgrade would be harmless to aesthetics and eliminate all the fouled carb problems associated with TW's

I’m glad to see more people thinking about going FI on our little TWs.
The last time I looked into it, the biggest obstacle to overcome for our bike is the fuel pump. The best I could come up with was an external on from a Suzuki LT500. If you watch on eBay, sometimes you can find one for an almost reasonable price. They are $$$!

I've been fortunate, 5 yrs. and 14,000 miles on my '13 with no carb issues. My '96 "Buddy Bike" has also been reliable. Not storing them with ethanol gas in the tanks has worked out great for me.
I store mine with ethanol gas all the time. All winter in fact, sometimes longer (no choice, can't get non-E). I always store it with Sea Foam in the tank.

The trick to never ever having an issue (for me over many years) is to have a fuel filter in place, having fresh sea foam mixed in when starting the store-it period and most importantly:

ALWAYS ALWAY ALWAYS drain the carb with the drain screw on the bottom that was in-fact put there for that purpose. Then run the engine till it dies from lack of fuel.

I have never had a problem since I started doing this years ago, it only take 60 seconde of my time, the bike idles and purrs like a kitten every time.

The tank looks shiny and new inside, never has slime and the filter is always clean, never been changed (it's a clear right angle filter with a screen).

I always mix the sea foam in and let it run long enough to make sure it's mixed fully and through the carb (a five minute ride).

Before I started this exact process I always had to battle it to get a good even idle and at times getting it started was a process to say the least.

So, Add sea foam, mix it in thoroughly, run it through, use a good filter and drain your carb every time your done with the bike and you will never have a problem guaranteed.

It's worked for me for 5 years flawlessly, even last year when i spent all my time on other bikes.

Use the right screw driver on the drain screw and you'll be using the same drain screw for at least 5 years without issue.

Unless you're frequently traveling between extreme elevations and have an authorized dealer on each end who has a computer to service your EFI I don't see the point. I bought my 2015 and did little to maintain it except add a fuel stabilizer and run the carb dry before storing it for more then a month. Now I ride year round so I do nothing but keep it running. IMO adding EFI to a TW would ruin it's classic simplicity and easy to work on nature. For the price of EFI by the sounds of it you could buy a new gas tank, carb, and airbox and have no problems if you maintain it accordingly.

Unless and until you've seen the brilliant simplicity of the vavnan's FI it's impossible to see why this is a worthwhile upgrade. While TrailWoman may have not had carb issues I can say the great majority of TW owners have and still do have carb maintenance issues some spending up to $500 by scammer dealers for so called carb repairs (and ALL dealers are scammers)

I've owned a few TW's and I'm pretty sure I had to repair every carb even on one I bought with 4 actual miles, perhaps 2 or 3 TW's out of a LOT I've owned or helped people acquire did not need carb work

I know the great majority will prefer this conversion once they see it in all it's glory

The Throttle body has the fuel pump attached directly to the injector all contained in the throttle body and gravity fed just like any MC carb Due to the low fuel volume there is no need for a high volume in tank mounted / cooled pump

the system is completely modular and would be as easy if not easier than maintaining a regular carb thus making the TW even simpler

Here is something that I have wondered about fuel injection.

If your battery is completely dead, can a fuel injected bike be bump started, or kickstarted, if it has a kicker?

Or, are you out of luck and pushing your bike?
you will need to have a battery with a charge but most of us do

I bet you could start the TW with a teaspoon of gas in the spark plug hole with would allow kick starting enough to get voltage output from the generator

you could also carry a lithium ion starter pocket pack to get starting voltage with a dead battery

even if it wouldn't work I'd still prefer the FI over the carb

this will be an optional conversion we will not force any of you to vote for Trump or to convert to FI lol

That is a great question. I asked it as well to a Husqvarna engineer at an event.

He said all the electronics is why new huskies have no kickstart option. Not enough juice..

Whether that applies to all forms, makes and models of fuel injection I can not say.

He said the injectors, pumps etc used too much juice.

In my case, two injectors, two pumps and two spark plugs in/for one cylinder. Then add in a huge ecm, emissions controls, always on lights, air pumps for the emissions, relays.. etc..

BUT it is 80 horsepower so I: "put up with it" :)

So in my case a battery is needed. Bump start, never tried it. If the battery ever dies way back in the pines.. I may too. It's a long walk. The sand is just to deep too even push a bike a few feet no less bump it.

Again, great question and a valid concern. That's why my deep expeditions are generally on the TW. I trust it. Granted the Husqy has been rock solid reliable.. However, it really is a rolling computer.

Sounds good Fred, probably just need a crank position sensor, and a few other things. Send me the bike, i'll test it ;)

The better, easier, and more cost effective solution might be to just buy a VanVan.:D
funny you say that because the more I look at mine the more I like the design over the TW so other than the 1.5 inches less front fork travel on the RV200 I love everything I see. If the DR200 tank can be fitted that solves the fuel capacity issue at 3.4 gallons but the stock vanvan tank is the same as a stock TW

I have done only 1 carb overhaul at 40,000 miles on my TW using ethanol contaminated gas. I Kreem tank lined my tank. The Kreem kit I bought had enough for 2 bikes so I just did the TW with the extra after I did my other bike. I put Marvel Mystery Oil in, about 1/2 ounce each tank. It worked for me. At minimum I ride it weekly. Fuel injection would mainly be superior for those doing major elevation changes during their rides.

I agree with not trusting dealers which why I don't understand how FI frees you of dealing with them. Maybe you deal with them less often then with carbs if you don't do your own repairs. Otherwise is this something you could repair yourself? I've been led to believe only authorized dealers can do anything with them.

It depends on your skills and the bike. Most KTMs have aftermarket programmers and ecms available, you can download custom fuel maps, change timing and advance. Make your own fuel maps. It usually takes a year for the aftermarket to catch up with new models so you enjoy your oem warranty for that year and then start playin when it's over. It's really much easier then you would think and there is a big community to help.

with the vanvan FI you are never going to need any dealer computer tuning or any of your own computer tuning there is probably nothing programmable simple replacing a control module in a worst case scenario like a fire I doubt the control module would ever fail under normal riding

TrailWoman never said anything about FI freeing you from dealers it's just for every person here saying they have never had carb issues I know of a thousand TW owners who have hell I buy carb parts by the dozen and reorder often lol

One thing I haven't found on the vanvan is any kind of crank sensor I don't see it in any crank or crankcase diagrams nor in wiring harness or electrical parts diagrams. this is kind of an unusual setup perhaps it can use the magneto trigger as the position sensor ???

This is a common misconception. But in reality it’s a non issue. Speaking as a professional licensed mechanic for the past 18years. Most fuel injection systems are FAR FAR less problematic than carbs. Think about it there just simply less parts to go wrong. As for needing a scan tool with a simple TBI injection system you really don’t. There’s nothing there to worry about. You have a fuel pump an injector and a control unit/ecm and a couple sensors. It’s about as basic you can get and all but the computer can be tested with a bloody $10 multimeter that takes just as much training to use as cleaning a carb (which I have had to do on my TW and Ozark. 250).

That being said when was the last time you had to bring your car in for a fuel injection issue. I’d reason to bet that be a very very rare occasion because generally very little fails with fuel injection.

And fuel injection is NOT a new concept. It’s been around in gas engines since the 1930s (bmw famously had it on thvery reliable messersmit BF109 wwII fighter).

Simply put fuel injection is superior to carbs in EVERY single way.

Now as a tech I’m fine running either as I can deal with either. BUT that being said I have NEVER had to touch any or my injected machines. And two of the three carbed machines have had the carbs pulled to be cleaned so there is that.

No FI, but still voting for TRUMP!
