i'm a pridor user let me tell you honestly pridor can only reach 90km with genuine settings and with custom it may touch 100 and nothing more.I have done 12000 on my ride and still smooth so if it's just knocking i.e. jerks at high speed then you may need to balance the octane no of the fuel you are using and you can do it easily by adding high octane in your fuel tank.Now the question how much so its depending with quality of petrol you are using .normally bikes require 90 octane no and petrol pumps provide 85-87 so to blc it you may use the ratio of 11:1 or 8:1. I use 11:1.
So even with famous deluxe the only reachable is 105km but gs150 can offer you 120km speed.
If your bike stop giving issue with high octane then its good otherwise you are welcome to pridor club.
I would also say its better to give a chance to suzuki you may also check your user manual and check valve clearance. it must be between 0.05 to 0.10 so with that info go to a harware shop and ask for feeler gauge or they call it tappet patri and consult a good mechnic to adjust tappet or you may take some help from pakwheels if you like. Coz a better valve clearance can give you a better thrust.
