How long before we see a Fuel Injected 2 Stroke Gas Gas?

2020 model?

I'm not blaming Gas Gas for holding onto carbs, it seems sensible to let the other manufacturers do the research and development, then make the move once they know more!

What I really like about the fuel injected 2 strokes is that not only do they control the fuel/air mixture but also the amount of 2 stroke oil that's injected into the engine, so at low rpm/low load the oil mixture can be as low as 1:100 then at high rpm/high load increase to around 1:33.

So I can only assume this reduces oil consumption, smoke, emissions and spooge, etc.

Just hope they can make all the extra electronics, etc. withstand everything that hard enduros can throw at them.

One of the primary reasons why I bought a GasGas is that it isn't fuel injected. It also isn't 2,000 pounds more expensive due to the addition of EFI.

KTM have a long track record of using their customers for product testing and their EFI models are still a long way from sorted. They have also created a bike that is now probably more complex than a 4 stroke.

KTM is also having lots of problems with TPI. A large portion of the oil pumps are failing without warning and ruining engines. I don’t want it for at least 3 or 4 more years while KTM, TM, and Sherco get it all sorted.

Ouch, that looks nasty...

OK, let's assume that's genuine, I mean the hour meter is on the same bike as the piston...

I have many questions...

Was the owner at fault? Did he put oil or the correct oil in the oil tank?

What caused this? Did the oil pump simply stop working?

How many engines have failed in this way?

Is there any monitoring of the oil pump within the bike's electronic system?

I used to work as a CNC machine engineer, very expensive laser cutting machines. Many times I arrived at a customer's machine and had to figure out why a machine had failed with a view to giving feedback to design engineers to prevent it happening again. Sometimes it takes some detective work!

However, if this is genuine and it's happening to a large percentage of engines then of course it's not acceptable.

I was just reading a thread on the ktmforum.co.uk

It seems that KTM recommend the oil pump to be replaced after 80 hours and cost is GBP 120...
