yes i noticed a diff. the veforce had alot more punch. In the second vid with the veforce i didnt hav it jetted right or it would have been more xtreme. Iv read you dont hav to rejet avter vforce reads but i believ otherwise. Befor the vforce i was runing 300 now im jetted at 340. And its a monster of a 200cc two stroke. Cant wait for a port and polish. PS. im 200 lbs helmet cloths and all by the way
