Hello, so I’m here on behalf of my dad, and he’s driving ne Yamaha Thunderace (YZF 1000 ), supposedly quite openly with 147 hp and a Figaroli end pot. now the “problem” that the machine only goes 250 km/h final speed according to tacho. we tried it once with the speed/speed ratio. at 4000 tours in the 5th course he drives about 100 km/h. at 11000 tours about 250 km/h. but he would have to drive about 3 times the speed at 3 times the speed With my car that’s so, I drive at 3250 tours 120 km/h and at 6500 tours exactly 240 km/h. his dealer has said schin that it’s on the pot, and that would take so much ps, but even my ZX 6 R drives according to tacho good 260, I’m also faster than he in the finality, have tested scho times on the empty highway. what else can that lie, it is said that you can cut somewhere still a white wire, so that it is open. thank you for the help
