RXX dies about 4500 RPM

Here is what I have. On the picture that has the 4 ski's I sold the blue one and replaced it with another yellow RX. That one also includes one of my RXX

Solved the issue.

I replaced both spark plug caps and it runs perfect. Had it up to 6800 rpm and was cooking down the mississippi
