Engine cutting out when using electric reverse
As per title really, my hayabusa engine cuts out when i use the electric reverse. It still keeps reversing ok but even if i rev it to about 3500 rpm
it still cuts out. It did throw up 4 fault codes which were ignition signal 1 2 3 and 4. Any ideas?

I'm guessing your electric reverse is taking a bit too much juice? Do you get a significant voltage drop when you're reversing?

It's likely to be the voltage sagging spectacularly under load. Try monitoring the volts across the battery when reversing, you might need to
install a bigger battery to prevent the drop. Normally of course the alternator provides all the electricity when the car is running and the battery
just provides it for starting but when you're using an electric reverse it's quite likely that you won't be producing enough oomph
from the alternator and it will be draining the battery.

Park it on the level and push it.
Not kidding. I've got leccy reverse and used it once in 3 months. I park on the flat and roll it into 'launch' position.
There's never a shortage of volunteer pushers to get a close-up of the car.
Knowing what I know now, I'd never have spec'ed it.
A good few owners have removed the reverse and found the gearchange much smoother.
Bottom line, only stick with it if you really need it. At the first hint of a problem with mine it's coming off.

My R1 engined car used to do the same when I used the standard original 4ah battery. I have since upgraded to a bit bigger battery with 19ah and it
works much better without cutting the engine :-)

Just sorting the same problem at the mo on my R1
Standard car battery does not work but as soon as I put my yellow top battery on the engine stays running even whilst reversing up a slope with 2
peeps. Just does not fit on the scuttle panel

They all do it, just restart it when you are ready, no problem. I use mine fore moving the car arround the drive, thats about it. How on earth does
removing an electric reverse improve the gear change ??????

It's good to know it's not just mine then. I have a massive battery from an rx8 fitted in the passenger footwell atm but it has been run
completly flat a few times a while ago so it may be fubar. It was flat when i started the engine and then left it running for about 1/2 an hour to
charge up but i guess the generator isn't really up to the job. I'm going to give it a good charge and see how i get on then. Has anyone
got any thoughts on fitting a capacitor like the ones people use for audio systems so the initial load on the battery isn't as much.

Bikes struggvle to charge their own batteries if totally flat, a good charge every so often helps condition the battery

Why not have 2 batteries wired up like a camper van with the reverse lamp acting as an isolator feed. The engine wouldn't be affected and you
could flatten the reversing battery without touching the main battery.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Apologies Austen.
I was mistakenly conflating different inputs and issues.
The u2u's I've received were from owners who'd removed the electric reverse because it was a pita.

All sorted now. Got myself an exide agm battery and now I can reverse to my hearts content without it stopping the engine.

Its an Exide AGM battery that I put in mine, and as you say, reversing is so much better now :-)
