Help....engine surges in reverse

Today I started the 700xx to move it. I had a ride two days ago and everything was fine. Today I put it in reverse, gave it some throttle and the engine began surging. If I gave it full throttle it would somewhat clear up. But as soon as I tried to move backward again, back comes the surging. Moving forward through the gears everything is fine. This only happens in reverse and I have no idea what to look for as far as a fix is concerned. Has anyone had, or heard of this issue. Any help would be greatly appreciated.

There is a reverse rev limiter on the XX. Sounds like it is acting up. Do some searching on "reverse rev limiter" and see if anything comes up. I know I have seen discussions on disconnecting that limiter.

Definitely a good idea to by pass the reverse limiter.

It may also be a good idea to look and the sensor's. Look at part #11 in this drawing. The one on the left is the neutral sensor the one on right is the reverse sensor. I tore my boot on part# 10 and when quad ran into deep water it would stall out. And later the ceramic on the sensor cracked so I replaced it and the wire harness. These sensor's are on the left side by the foot sifter. To access I had to remove side plastic and heel guard. But I got big monkey hands, lol
