My TRA primary clutch augered itself to pieces. Ordered up a polaris p85 with Doo taper. Put in Blue primary spring from comet and 65 gram heavy hitter weights from thunder products. What an awsome mod.:d Engagement is smooth and excelleration is amazing and strong no matter the rpm. Top rpm is 8100 around here. Has anyone had similar success with this set-up and or any other modification that has worked extrmely well.:d
