Qsc Xmr850

Just got my qsc rev x from 3p off-road and seems good but when I get up to where the speed limiter kicks in 65mph it starts to bounce of the rev limiter. I called 3p they said change tip weight from 1/4 to 3/8 to fix. Changed it and it still does it and now 3p won’t return my calls. Any suggestions or is this normal for quad with clutches and a speed limiter
