Hey Everyone.
I have a 2018 Uforce 800 with just over 6000Km. So just recently I was traveling down the road and had the pedal to the floor and the machine got to 70k/h and it felt like it hot a wall and would not go any faster. It sounded like the engine was struggling , I let off on the throttle and the engine smoothed out and was able to get a bit more speed . I put it to the floor and checked the RPM and it would not go past 5500 RPM and the injector light came on .  I stopped and and shut down the machine and started it back up and the light went off and tried again in low and still can't get it passed 5500RPM. I checked the clutches and cleaned them and sure there's a small Grove in the primary sheeve but I can't see that causing the issue.  If I put it in neutral and rev it up with no problems it revs up to 7700RPM no problem.  I checked the manual and can't really find anything relating to the issue.
Has anyone ever had that issue before and what was the fix.

Thanks.

Hey guy's I just got my machine (2017 z-force 800) back from the dealer after having a complete "platinum service" done along with new belt and other suspension related repairs. My question is my top speed sucks. I use to get 67mph no problem, now I'm lucky to get 52mph and I get a warning light that comes on. Red light next to my "Park" indicator. Manual says EFI fault? Any one else have an issue like this? Is this normal with a new belt?

Mine is doing the same thing. Did you get it fixed and what was the issue

EDIT: I have changed this thread to a "How To" instead of a question. Hopefully this will help others, as I couldn't find anything on the internet about it.

Many people don't know this, but there a a governor in place to restrict the throttle. It is a part of the wear in process and should remain on for 750km's or 20 hours. It is normally removed by the dealer on the first service. In some cases where the user has serviced the vehicle themselves or the dealer has overlooked it, it may need to be removed on your own. If you are not confident on doing so, consult your dealer. There should be no charge for this.

Step 1 - lift passenger seat. and remove air filter, so butterfly is visible.
Step 2 - Locate and remove throttle cover on passenger side of throttle body. Roughly 50mm in diameter. Glossy black in colour. 
Step 3 - Locate 'wear in period" throttle limiter. (see picture). when pedal is compressed, you will see the throttle hit this bit of metal. you should also check the butterfly is only partially open, to confirm your limiter is still there. it is meant to be removed during first service.
Step 4 - Grab metal piece with pliers. Gently bend side to side, with a slight twisting motion. The metal is cast in a way that it is meant to break off.
Step 5 - Remove bold from behind accelerator pedal. A slight adjustment of the cable tension may be required at the throttle body. Judge this for yourself. The butterfly should move a 90 degree as the pedal touches the floor.
Step 6 - Replace all covers and the filter.

Step 7 - Enjoy the new found power. Caution, if you are not used to it, take your time. The U800 will break traction every time you accelerate to full throttle and begin to slid the back end. this may be a shock to new off road drivers.

Just bought a 2018 U800 and one of the first things was to check and see if the throttle body was opening all the way at WOT and it is , I haven't checked for the plate or pin your talking about but if the butterfly is 90° then I'm guessing mine is removed and adjusted
