4VS or 4VD

Hello friends,

I have fast question. What type of Thunderace have a full power (about 145 PH) 4SV of 4VD?

My Thunderace is on 1998 and i have number 4VD on the frame, engine and ignation module. But i have too numer 4SV on the cable harness and on the air filter housing.
My Ace on the first gear going without a problem about 120+ km/h, My top speed was about 270km/s. So my Ace is blocked or no.

I have'nt blocked membrane in the carburetors.

So how can I check what is power on my motorbike? What is a Top speed Thunderace with 100PS and 145PS?

Ty for all answers. My Ace is 145PH. Btw i love this motorbike
