MOTOGP STARTER UPDATE

[Neka79]

Bump starting FI works.

EFI maybe not

mines a bitch cos wen u turn on the ignition, u can hear the fuel pump prime....without power, u can roll start the farker all day & she wont go...

The problem is I need to have the bike spinning in gear to prime the oil
in the motor ( it has a kit oil pump ) with the egnition off. For 20 to 30
seconds, after a while without running ( bettween races or ride days).

Man.....How much power is that thing putting out????? Kit oil pump? What else has it got??????

28L rolls jet engine...

5 speed celica box (the heavy duty cast one, not the aluminium one)...

I was told it had around 145Hp at the wheel.

what abt a 13b rotor..thats abt all there good for...

Come race my slow 13bt RX3 some time Neka. I'll give you "all their good for"

Considered 2 starter motors?

My setup can't mount a second motor.
So have to think about my other options

just curious, what gear are you trying to start it in?

you never use first when push starting a bike, 2nd is usually the go... but if its still too hard, maybe try 3rd?

I was having a go in 2nd then 3rd. still no go
was thinking of running it at 18 volts but don't know if it
can take it.

could be dangerous


what are you using for a power supply? and what size cables?

Why dangerous?
I havea 850 CCA battery & am using 8mm cable.

as in it could burn out the starter motor


do you have a multimeter?

use it to measure voltage at the battery terminals while trying to start the bike, then measure it at the starters terminals while trying to start it to see if there is any voltage drop

What dose it mean if there is a voltage drop?
Also its a 3 post motor ( winch motor ) across
what terminal do I measure the voltage?

[SocialSecurity]

basically measure the voltage at both ends of the cables, at the battery and at the motor (which ever terminals the wires are connected to)

if there is a voltage drop then it means the cables are too small

if you have say 10v at the battery while cranking but only 8v at the motor while cranking then thats a lot of juice not getting to the motor. in that case, try using two runs of the same cable so the current has double the cross sectional area to pass through. also try and keep the cables as short as possible.

if theres no drop then uhmm.... bugger eh
