hi anyone, is hp4 really worth it on px200? anyone please…thanks.
malossi 210, match port case and inlet, malossi manifold with 30mm flatslide, t5 4th gear, but i think i need a fuel pump coz i notice im having a fuel starvation . im getting this high peak revving at the top then bogs then speed ruduces down but when i closed throttle a bit it recovers again. what do you think is the problem?
HP4 is not bad, but i think that a modified original flywheel works also great !!!
wich engine specifications do you got ??
cylinder ? carb ? etc...
