Poll 2019 KTM XCW 300 TPI 6 Days
 

Like it or Hate it?

Is fuel injection the future for smokers?

This thread needs a picture! :p

While I like the idea of TPI, I do not like KTM's implementation of it. A buddy has the 250 version and after an easy get off he took a minute to look over his bike. I asked what he was doing and he said he had to make sure no air bubbles were in the oil feed line or it could damage the engine. He said the owners manual said it needed to be checked after a get off. I would imagine that would be real fun to try to do during a muddy race or ride. They need some sort of automatic air purge so this isn't an issue IMO. Of course, they are still fairly new so we'll have to wait and see if I'm imagining a potential problem or if it really is one.

That's a good question. I rode a friends 250 XCW TPI & really liked it. But I didn't crash it, thankfully.

Maybe run a little oil pre mix just to be on the safe side, in the event of a momentary oil starvation.

surely an air bubble will show up as 2t oil reservoir being empty? Or would it lock up the flow?

Anyway will keep the men in white coats employed for another year and give the lemmings something to buy next year

You "can't" add oil to the fuel. That would change the flow rate of the injector.
That said, you can buy a $900 GET programmer to change the fuel injector and oil flow rate.
GET also makes a throttle body mounted injector set-up. It deletes the port mounted injectors.

I can't see how adding dissolving 1 ounce of oil (that's made to completely dissolve) into 100 ounces of oil would change the viscosity of the fuel enough to have any impact on the flow rate.

Here you go!

I was just checking the price on the standard model, its $9899.00 USD which isn't too bad for fuel injection.:D

I have never had a complaint with the KTM power plants. The chassis and suspension however, will likely never be a good fit for me. It is good that KTM is doing the R&D (through their customers as usual) on the port injection, as it will benefit other manufacturers as they develop their own injection systems.

From what I have heard the TPI versions of the bikes are a little softer on the bottom end than their carbureted counterparts. I was surprised that KTM did not provide a method to change the mapping and/or power delivery on the 2018 TPI bikes. It seems that this would be one of the benefits of fuel injection on 2T bikes. Perhaps this is something they have/will address with 2019+ MY.

I don't think that would be enough oil to keep it from seizing up. :(

Husky announced, no carbs for 2019 on.

Wow, they are doubling down on that technology.

That's an Australian article, do they have the TX line down there? As far as I know, there's been no mention of of the 2019 TX's in the US, but I'd guess that they'll still be carburated like their KTM counterpart the XC.

As for the air bubbles, I'm not sure how much of a worry there is. It's probably kind of like how the manual says to change the piston every 10 hours or something nuts like that. I know of a few locally who've had the injected 250s, one rode it in the pro class at King of the motos, and you can watch a video of him in the pro only race #2 launching it up the waterfall at backdoor. He definitely didn't waste any time checking it out after and I'm sure that's not it's only drop that day. One of my buddies bought that bike, and he's hard on equipment too, no issues with that either.

Personally, I don't want TPI because carbs work fine, but if I had one, I don't think I'd stress the air bubble thing.

The US Huskys are TPI.

Just found this, TX has a carb...

You can see it in the pic at the first link, and scroll all the way down the page in the second link and the mikuni carb is listed in the TX's details

Again, this is for the US, the other article posted was Australian.

For several years I ran Amsoil Saber (made for 100/1 mix ratio) in my 300 at a ratio of 75/1 and it worked great. No engine problems at all.
