There is a limiter when I’m Neutral I’m not positive what it is but around 5 k sounds right
I have tested that theory when I did my clutch kit my helmet fell on the peddle lol glad I always leave it out of gear
But in gear no limiter on mine
But it did struggle to get over 5500 with any load or hill etc
I’ve got 93 hrs an 1800kms on it
21 uforce 1000

^^Yeah, rev limiter for neutral makes total sense.  This thing clearly has electronic limiter, as it is so obvious in low gear at 5500 it just shuts down. 

Dealer looking at it next week, but I'm buying OBD2-USB cable and going to look at file on ECU to see if limiter built in, or some faulty issue.

Is it perhaps just that you do not have the seat belt fastened?

I believe there may be a switch in the seat belt system.

Ha, no, I wear the seatbelt.  The cause is...drum roll......I'm an idiot.

The machine has the "work" and "normal" mode.  In normal mode, the throttle is soft and it's a pretty pathetic machine.  In "work" mode I can get the speedo to 75mph, which we all know is bullshit and really about 62mph.  Machine is fine, operator was expecting too much.  I guess "work" - "normal" mode must affect ECU or clutching somehow, because it is night and day different.

The limiter is certainly there in "low", but that's fine and expected.

Good to know. Waiting on my 2022 delivery, so looking to get all the anomalies and tricks figured out.

Read someone else had an issue with a “seatbelt interlock”, but was not UFORCE 1000.

Your issue is more “respectable” than a top end issue a buddy and I chased in another rig years ago…. Lot the top end… because a THICK rubber mat was put in….. and the throttle pedal did not go all the way down!

Have you found ability to calibrate the 2022 speedo?

I haven't bothered to attempt calibration yet, don't really care much.  I ride with my GPS for speedo when in town or on paved roads to avoid a ticket or keep pace with rural traffic.  Yeah, nothing wrong with this machine, I was just being dumb (I can fully accept that).

It’s not the speed difference that is particularly an issue, but putting an extra 120 miles on the Odom per thousand stacks up some.

 (I seem to see suggestions of the ‘21 and prior models being off that much).

^^Good point, but there's an hour meter too, and that doesn't lie.

Plus, I'm running tracks, mileage is pointless.

I have this issue on a 21 uforce 1000. I do have a full DFK cab. Would the weight of that affect the machine that much? There has been a handful of times where it has opened up and felt like a whole new machine. Floor it and RPM hovers 5300-5500 then climbs slowly as speed slowly increases

That’s how mine worked with my cab on an 30” tires clocked to c1

So you originally tried clocking at C1 and it didn’t help? I read stock is clocked B1..
Stiffer spring and what gram weights?
Thanks for the info

I clocked to c1 with no cab an 29”
Tires it struggled then so

I now run
200/1600 spring
#0951-1017
18g weights 
An clocked to b2

I ordered all from revco in Canada weights an spring
A 1/4 of the cost of a “kit”  with the same parts lol
