ZX12R A1 Removing Neutral to Start, TRE & clutch help.
I got my stuart-taylor seven through SVA earlier in the year and have done 1100 miles in the past 5 months, but have done nothing to the car other
than drive it. On the long list of “things to do to it but haven’t looked into how to” are:
Removing the safety lockout that means you have to be in Neutral to start, what’s the best way to do this as I know full well I will spin it and be
sat stalled probably mid corner fumbling round for neutral to start it.
TRE’s Timing retard eliminators, rumour has it zx12r’s retard the timing in low gears as a safety feature, and if you wire the 1st 2nd and 3rd gear
position switch outputs to the 4th gear ECU input it should prevent timing retard.
Im running a speedo healer to use the original clocks will this have completely removed the op speed indicator by fooling it that it’s going slower
than it is?
Also a few folk have mentioned the clutches on A1’s are fragile and lack lubrication and I should change it for a later models assembly, which bits do
you change and why?
Many thanks in advance

Hello,
you can bypass the power restriction by adding a "G pack".

as for the clutch just fit a new set of genuine plates and some ape springs check your steels are ok if you like you can mod the basket centre drum
with small holes for oil to pass but i would try new bits first see how you go .jpg)

Hello,
sorry Paul, but as far as i know, the standard Ecu on the ZX12 does limit torque on first and second gear.
So , if you want full power, you have to go for a G Pack.
It will let the Ecu believe taht 3 and 4 gear are engaged.

I was under the impression that the zx12r a1 model the one that is refered as the full power version has no built in restrictions.

Cheers for the posts.
I keep finding conflicting posts on zx12r torque limiting in 1st 2nd and 3rd, there are firms selling dedicated zx12r TRE's I wonderinging if
its region specific.
The clutch to date has been spot on, the (2001) engine was almost new when I got it (thats how long it took me to finish it!) but id be interested to
see how it survives.
So then how do I get round the neutral to start lockout?

Hello,
Removing neutral start is easy, just fit a clutch switch like the bike has,
When pressing clutch then you can start the bike in every gear.
