I was about to flame Jason over this...but I see it was a kit, that I knew was coming. Didn't know it included new heads. Sweet. Betcha they will say 2014 and later...but my 2011 Retro would sure like me to do that to it as well...would love to have it run like my GearUp. That would be the perfect Ural to me. Wait, did he say production mule...I like mules... ;-)
My M70/Retro "kit" was actually a one off prototype for R&D to help them evaluate if a kit would be economically feasible.

The 2020 pistons, rings, cylinders, heads, breather, oil pump, and sump aren't necessary to change, or included with the kit, I paid extra for them. There was nothing wrong with those items, Jason and Nik told me several times that the improvements in performance are from the EFI kit alone. The mechanical upgrades are for long term durability, and better tolerance of high speed, high load, high temperature abuse. No need, just peace of mind.

They also went through the engine, clutch, and transmission for unrelated QA purposes, and changed some other things out at their expense.

For the jerky throttle condition you might just have to get used to it and may go away. If it doesn't try a Throttle Tamer G2, look them up on line.
I checked them out, and appreciate the tip.
I suspect its just a matter of me getting used to the instantaneous throttle response, and lighter throttle return springs, but may still try the tamer some time later.

Well....that's what the folks at IMWA are calling it, so I'm sticking with it. :lol:

Just picked it up today. Only put 30 miles on it, and have to do the new engine break in thing, so have to take it easy, but still can say the difference is amazing.

Gee, compared to Christine, the evil M70, I really like the 2019's throttle response, even like my wonderful gas sucking 2011 Retro over the M70's come to think of it... My '19 proved what windmill just said the 1st time I had to pass a Masshole on the Mass Turnpike and found myself doing an unobtainable speed for my '11 or '15 instantly and quite accidently (it's on the ride home video)...hmmm, entire engine and wiring harness cheaper than new bike...oh that is such a bad thought, only have 98K on the 11's engine, barely broken in...anyone hung some carbs on the new engine to prove that it really is the EFI making the big difference?

Was the EJ really that bad :?

For a few it was that bad, like most I didn't find it that bad. It was really luck of the draw.

Barry, have you got any warranty for your new engine? Regular warranty for a new engine?
I think many will be interested in this question.

My situation is unique because it falls under R&D, and so would addressing any premature failures as there's some inherent risk in field testing prototypes.

For retail, I believe it's the normal 30 days for DIY parts, and whatever it is for work done by a dealer.

The 2nd generation EFI was developed on standard 2018 engines, so it was proven to be 99% due to the new system, not the mechanical changes.

Appearance-wise, if you kinda ignore the disc brake rotor, the bike looks very vintage. If someone wants a vintage military look, that's the one to have.

I'm still not a fan of black engines. But that's just me.

Me too, Rob. I believe a silver motorcycle engine looks correct. For $750.00, I surely don't see the value proposition for the black engine option, either. My selling dealer tells me that it's fairly popular, though, at least for his sales.

I will say that the black engine paired with a gloss white bike + sidecar does look rather attractive.

Some observations after a week.

When the key is turned on it does an initialization cycle and the fuel pump comes on as with the EJ system, but once up to pressure it cuts off like the 2019 in tank fuel pump.

It starts quickly without any hesitation and settles into a high idle, after 30 seconds or so it drops down to a lower idle, after another 30 seconds or so it drops down more and then adjusts itself to a normal idle that's very smooth and steady. It doesn't need the throttle open pre cranking in the cold like the EJ. It's not a huge difference, but the retrofit kit cold starting and idle is a little better than the standard 2019.

Throttle response is instantaneous and exactly matches throttle input, There is no lag or need to over throttle like with the EJ, and CVK carbs. Its taking some effort to unlearn my muscle memory, and not over throttle when starting from a stop.

The low speed, low rpm skipping of the EJ system is entirely absent, and can't be induced.

The exhaust note is noticeably different, more of an even growl then a ragged grind, and the wet puttering and occational popping on a trailing throttle is gone. The mirrors are significantly clearer too.

The engine sounds are different, the gear clatter is more subdued ( because it runs smoother?) and the valve tapping is louder and more pronounced (bigger fins and valve cover amplifying the sound?)

My first fill up shows no change in MPG from the EJ.....but I've been on the throttle more than normal, I've barely started to break it in yet, and 1 fill up is pretty meaningless.

I won't go into the increase in torque, HP, hill climbing ability, acceleration, and rideability as been well covered by others, but one thing that was pointed out to me is the retrofit kit actually produces an extra 1/2 to 1 hp more then the OE 2019 because the external Delphi fuel pump runs at a higher pressure. My M70 feels peppier than the loaner but can't say if its the extra HP , the smaller 18" wheels, or both.

I have yet to experience any undesirable traits in the 2nd generation EFI system.
