Strange lost rpm but not km/h need help :(
Something strange is happening to me. I have a 04 rxp with X steering which mean I don't have the mode button (mph, rpm etc..).
Before the rpm gone I was doing 8000 and 112km with my old xs intercooler.
On wesdneday toke out my girlfriend oem rxp steering, put the rpm back to my ski, and then test it .
I did 7250rpm and 113km. The only thing new I put was riva spring kit,(not yet the riva ecu need 50 injectors) rotax head gasket, bigger XS intercooler with greedy BOV and gibson exhaust. I found these number strange how come I have more km/h with this low rpm???
Am I losing pressure somewhere? I'm going to try my old XS intercooler to see if it changes cause the guy who service my ski told me that the new intercooler is too big for my configuration and that I'll lose power, compare to my old xs which was smaller

You lost a bit more than usual but this is normal when installing the riva valvetrain.

the thing is that before installing the riva valve kit, on my seadoo counter I had the same rpm (reading without digital rpm) can't find the word in english....
At first I thought my counter had a problem cause I didn't feel my ski lost power but when I saw 7250rpm I was like what the H..LL stupes

rotax head gasket ????
My guess is wrong cam timing

I have a 04 cam, how do you fix the cam timing?

I can put an aftermarket camshaft would it solve the problem or I can fix the timing?

More than likely it's normal. Don't over complicate things bro.

ok it's not overcomplicated things, Where I leave I don't have people like you all who can help me. And if I don't tell them what you all suggest me to do I will go in deep problem
So thank you all for you patience and your knowledge hehe
