I posted this on my phone and was going to delete it but couldn't figure out how. Especially after reading that there are actual differences within the 3rd gen bikes. I am happy that there are guys like you willing to get into the ECUs instead of just tricking the system downstream.

What I don't understand is why the manufacturers can't get it right out of the box. What makes fuel injection systems so difficult? You hear fueling complaints on just about every bike review out there. Is it because they are having to tune them to pass EPA tests?

I personally am anxiously awaiting this...
Seems like every vehical on the road today could benefit from tuning, and I suspect it is a matter of satisfying government regulations.
My boys play around with Volvo's, Saab's, and Subaru turbo cars, and simple ecu tuning can produce HUGE results.
My 2004 Dodge Ram was "built" by the original owner, has a 6.2 block swapped for the 5.7, new cams, a true dual exhaust, 4.11 rear gears... it should be a gas pig. An excellent bit of tuning by the performance shop that did the work has it pulling 22 mpg... with an extra 175 hp on tap... and on 89 octane gas.
Simply amazing what can be done these days.
I'm not really that much of a hot rodder (at least not as much as when I was younger) 😉 ... but I do like an engine that performs.
Now that I have a 2011 and a 2015 V, I can tell the difference between the two, and I like the older bike better, especially in the lower rpms.

My only question... if I were to put say, a spare 2014 ex650r engine in the 2015, could the bike's ecu be tuned for that, or would it require special "testing"?
I don't really know why, but a "surprisingly" quick V has a certain appeal.
Maybe that old lead foot isn't completely gone... 😉

You're talking about tuning the 2015 ecu to the ex650r engine? Yes, I'd assume the ecu could be tuned to it, if you have the combination together and all the necessary equipment, including a good compliment of educated brain cells.

If you're asking if I would do that from afar? no, I wouldn't. I have high standards of workmanship. I don't guess and I don't just tune WOT and call it good.

And honestly, I'm really becoming surprised at just how much is in the little 650 v engine. Very capable.

Just joined and got this bike but will watch this product development closely. No low end power complaints on my 18 (advantage of moving up from a 200cc I guess) but the on/off nature of my throttle is annoying and surprisingly bad for something not drive by wire.

I first became aware of Kawi's little vertical twin when the top flat track guys began running them a few years ago, in a custom dirt track frame of course.

On the mile tracks nothing could touch them, not even the XR-750 Harley's. Must say it got my attention. I would imagine the tuners did all the usual make more horse power stuff. Aggressive cam profiles, serious head work, high compression pistons, etc. Think I read somewhere they were putting out right around 100 HP.

Guess the little V is like the little engine that could...and it really can.

I'd be very interested in a way to smooth out the throttle response in lower RPM's, especially when slowing down for a delicate right hand turn, and then having to throttle for power up a hill. The Versys just doesn't do that very well the way it is set up stock. I'd also like to get rid of lugging at lower RPMs.

what do you consider "lower RPMs"

For me it means below about 4k rpm. 2015 V650LT. That's where it runs poorly once warmed up. Obviously it is too lean there. When the engine first starts up it runs nicely in the lower rpms.

On town roads with speed limit 20 - 35 it doesn't take much power, but I have to keep it wound up to 4k rpm or higher to avoid roughness. It would be nice to be able to idle along at 2500-3500 rpm without the stuttering.

Have you (perhaps) got TOO much 'slack' in your throttle cables?

I've read the 100 HP figure TOO.

Maybe shift DOWN a gear or two....

When around 3-4k RPMS. Engine just feels too lean. Also throttle response is jerky.

No slack on mine, and I'm already in 2nd gear. I'm just not very comfortable riding this bike on roads where you have to slow down, make sharp turns, and then accelerate - the transition can get real jerky.

Nothing like starting a new thread and having multiple browsers open, then accidentally closing one of those with the new un-posted thread in it , just happens to be Gas Caps wip , so I started over with the links, going for a ride, back tomorrow, and yes I am a old guy too, the hand was quicker than the eye

I pull in the clutch and slip it some in a few places to remedy that problem. Shouldn't have to, but the alternative is to downshift into 1st and go screaming around the corner at low speed.

My '15 got flashed today.

I rode over to Steve in Sunny FL's house this morning. Both of our intent was to compare my stock bike with now over 46k miles on it to his bike with his flash in it over a varying route and nit pick on the flash. We did maybe 10-20% of the route and I told Steve that I want it. So we cut the ride short and went back to his place to do the deed. It's done.

One of the things that I requested is to mellow out the throttle response in the very low rpms to help with off road riding. This he accomplished. When on the pegs the throttle is much easier modulate. This only comes into play below 3k rpm so the mid range and higher is not affected. This is truly awesome.

Speaking of mid range, a noticeable improvement in smartly applied throttle. Where I used to get a rush around 6k or better, now that rush is not so pronounced because the bike is already making good power. Throttle response and performance is much improved in the 3k and up range. 4k actually has some umph now.

One more thing, Steve set the cooling fan to come on ten degrees cooler. Seems to work well with my Therm o Bob.

All in all, I like it. It ain't 100hp, but, oh well. The low-mid range extra punch and response is welcome and the reduced response below 3k is just plain awesome.

Gonna head up to the north GA mountains after Labor Day to really have some fun with it. Yeehaw.

Yeah, if you want true ram air tuning, you better be willing to ram some air! (SteveinSunnyFlorida)

That's great Steve. Sounds like a fantastic upgrade to an already great bike.

Now I just have to patiently wait until the flash is ready to migrate out to California.

Thanks for sharing.

color me interested. I do love that "rush" when cracking the throttle. Wouldn't want to lose that.

Wow, a lot of reading.........I was interested in this last year when it was first mentioned. I am still interested. I have to agree with most of the comments about touchy throttle (yes the cable is adjusted properly) and lower rpm "lack". It is a good bike but they can always be better. Price would be the only "caveat" for me.

I'm so ready to be flashed! Ever since this darn thread started, the on/off, low speed issue has really made it hard to overlook when I ride my 2016LT now. I've just lived with it as a funky characteristic of an otherwise awesome bike.

I've learned much from this thread and assumed this was a Gen 3 2015-2018 thing. Now I see the latest models don't suffer with it. They should be Generation 3.5!

Wish I could visit Steve in Sunny Fla, but its a bit of a ride from northern California!

Hope Steve gets it ready soon so I can send my ECU!
