If you are a tech geek or a very serious racers listen to the majority....having the feet dragging does not win a race or may be not worth the cost...it presents future problems... trans / etc..it sounds great in concept yet zipping around the streets a foot shift guy who knows his bike will stay in it or feather the clutch and get back in it...and whistle past you. An elec solenoid bypassed with the horn button seems to do jut fine...the pain is getting the throw of the solenoid to coincide with the throw / torque of the up shift...buy a proven kit or ask more questions.... I'm about done trying to get the two to work all the time
