Flywheel special HP4 1000g is it worth it?

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...
