That be a job for the oxygen sensor in the pipe, if there is any change in the gasses.[if there was one]

No not atm,I don't want to muck around with having to remove the head but he is doing an ecu only tune with the stock head very soon.This will be a big seller for him and will suit alot of non mechanical handed people if he can get reasonabe performance out of it. The more oil at start up remap feature is something i like alot also so i will most likely go this option when it's available.

Oil in the fuel does technically make the bike run leaner. It also reduces the effective octane.

The TPI also has the relative disadvantage of no fuel flowing through the bottom end, which might mean that the air fuel charge is hotter on a TPI and that is not great for detonation. I'm wondering if that is why compression ratios are lower on the TPI bikes. Maybe the fresh fuel getting spraying in at the transfer ports cools the air (like water/methanol injection) but I am not sure if the fuel is getting heated up on the way with the injectors mounted on the cylinder.

The GET package moves the injectors back to the reeds, which might have some advantages but it also more work to install.

Yeah - nup. A lot of noise for a little return it looks to me. Be great if I was 17 again. Or even 35.

So who’s going to buy the new 2020 ktm/Husqvarna

I brought the 350excf because I want to do some high country rides this year and see more of this beautiful land .
Today I did the first high country ride for the year. We rode from Reefton over to BigRiver and back.....85kms.
Man does this bike crack!!! This bike was awesome to ride today. I had so much fun. It’s amazing how the 350 is only 1kg heavier on paper then my 250tpi But the 350 just felt so much more confident riding at speed compared to the 250tpi . Not once did I feel like I wasn’t in control. The bike actually made me feel that comfortable that it made me want to push it harder to the point I was riding out of my comfort zone.
One bad point iv noticed with riding the 4ts is that I keep over shooting the corners .

The bike is pretty much stock. My heavier springs ( no valving ) fan kit , barkbusters & gripper seat, steg pegz, stock muffler, no ecu remapping.

Fuel economy was fantastic still had half a tank left.

This bike Rocks

Ditch the air fork, make the ECU tunable by phone(so they don't run hot or gutless) & add a kickstart & I'd be more interested.
Will they start on kicker with a bat flattery?

The TPI bikes tend to feel lean stock regardless, though they might not be.....it might be more a case that I like them running a bit rich on the pilot and have been tuning my carbs that way for 15 years.

I am aware that the oil injection may have been modified with the ECU retune but my goal has been to run the bike and see what is different apples for apples. Maybe I will try a couple of tanks "dry" and see how it goes?

I have 3 or 4 rides under my belt with the TSP kit, have made some minor changes, eg adding a map switch (can definitely feel a difference there) most recent being going back to the green spring (I had fitted a red trying to get a bit more out of the stock bike) but with the ECU tune it has a new mid-range spike in throttle response that is scary on the back wheel and it may well be because the ECU is calibrated to the stock powervalve spring.

I'm yet to ride and confirm that yet, but I have a list of items that I will discuss with TSP in the coming weeks. I'm not criticising TSP, I reckon it's tops that someone is tuning these bikes, but it all comes down to personal preferences, and it is early days in the world of TPI tuning...still a lot to be figured out. I wish I had access to a programmable tuner.

For now I'm just trying a different ideas, happy to exchange thoughts.

I did measure oil consumption during the first 20 hours, will do a repeat in the next 20 hours and see if there has been any measurable increase.
How did you find the green spring and have you got any more updates?
I did a few more days riding a hilly terrain area with the 2020 tpi and it was awesome. The 300 tpi engine doesn't lug down really really low in the revs like my previous carby fed 300 bikes and does lack a bit of torque in comparison in this area. I can now see what some riders are talking about and are clinging onto and why some hard enduro terrain riders prefer the carb motors characteristics.This must be a part of the current tpi design feature atm and hopefully it will be refined and improved as future year models are released.
The tpi likes to have a few revs into it to work better and then it is excellent. It's definately a different style of learning and riding but overall i think the tpi characteristic is better with it's near perfect fuelling and smoothness in all conditions and throttle ranges.
Personally i would like to see some more oil be used, as it's only using 50 to 60ml per tank, which i'm still not comfortable with yet.
