I recently bought a used 2000 zx6r. It was dropped. The intake tubes are duct taped together. I cant pop a wheelie when jerking the throttle. I ride to about 6-7k rpms in first, release and get back on the throttle. The bike jerks back but wont ever come up. Could it be how the suspension is set. I didnt do anything to the bike when I got it but change the fluids and sprayed some carb cleaner through the intake. If I drop the clutch, I can get the bike up at around 8k rpms, but it seems like my throttle response is keeping me from keeping the bike up. Second gear is almost useless to even try getting it up. Any and all help will be appreciated. Be nice im new to these boards.
