When you read adverts for these things, ie linked to PC3 it generally states push or pull.
Am I correct in thinking with bikes this is pertinent, but not so a BEC where the solenoid can be positioned appropriately to operate the gearchange
?
Also if its "push" only does it only do for example upchanges ?
Ive been nightshift so go easy on me !
It doesnt make sense...
A lot of quickshiters are still manual shift but with electronic gizmos to allow clutchless full throttle upshifts.
Slightly more sophisticated ones include a throttle blipper for clutchless downshifts.
The 'push or pull' usually refers to the direction you need the gear change link rod to move to shift up.
There is a microswitch/ load cell built into the actuating rod to sense when to bring in the ignition cut - this can be for a push or a pull.
The systems with both up and down shifts sense in both directions.
Then there are actuated gear shift systems using stepper motors, solenoids or pneumatic shifter.....

If its one that does both then it doesn't matter which direction is an upshift or downshift - you can just switch the wires to suit.
If its one that only deals with upshifts then i guess it may be built to only sense compression or tension so you need the correct one to suit your
setup.
Ok , so like I said the type of shifter whether its push or pull is actually about which way its mounted relative to the gear shaft ?
So on a Blackbird gearbox I could use a quickshifter push or pull system, as long as I mounted it the correct way to work the gearbox both up &
down.
Can the blipper be added at a later date ?
Im looking at used setups from other bikes to link into a PC3 to work on a Blackbird.
Whether this is locost or false economy I need to research further.
thanks
Flatshifter do the system that enables clutchless up and down gearshifts also electric gearshift systems with paddles
