I've been told they burn out and fry. Use at your own risk.
Next challenge--adjusting the in tank reg---fuel rail---aeromotive reg.
Anybody got a K8 head spare?

Pity there's a piece of junk obscuring the picture.

i thourt it was an add for a dildo

[spamanglenn]

but its cheaper so it must be better right? .afterall what could go wrong. .Ive got an intank walbro,it gives the standard fuel pressure regulator a workout as it flow about double the stock pump.

will that hurt the reg? at all

Will just have to scew it in & test pressure so it's a bit above what I want, then fit the fuel rail, then the external Aeromotive reg, then set pressure exactly what I want......I think ?
1580cc should be good for the strip & the road. Ordered a GSS340 type, but got a GSS342. At least the stock tea bag filter fits OK.

sounds like a good install let me know how it goes

you may as well plug where the regulator goes and run the aeromotive external reg with a return line welded into the tank pickup.thinking of doing the same thing.blackbird injectors at stock pressure is at about 90%duty cycle before ram air in 5th and 6th.might just put another 55psi crushed reg in for now.the first crushed reg died.

I just happened to have an Apex BPD that would fit Spam Jam's bike perfectly, only AUS$2500. Have a rap with Jamie, better alternative than Motec & than the BBS, won't fit a Gen2. I wish it would. Brand Spanking new.
I may not even have to bung the fuel pressure up, fit an MF2 & run it to the secondary 4 fuel injectors & bung 2 x 195cc/min RCs in the airbox.

That's my reminder that there's something better where the roads are no good. All to do with "Demographics"

im using about 1150cc to make 225 -230 hp.you have 8 X 255 cc injectors already there at stock pressure.At best your only going to use 1500-1600cc per minute which will only put you at 75-80% total duty cycle on all 8 injectors.Your stock pump wont keep up so just fit the walbro at stock pressure and be done with it,youve still got more in reserve than ihave with blackbirds at 55psi.Low pressure,longer pump life,fit a billet fuel rail if your stressed about adequate supply at the injectors.sae does them for the gen2.

In many ways, eg lower pressure, longer pump life-you're a mind reader. My only concern about the fuel rail is extra pressure, not flow, and it blows Was told the K8's inj. were 280cc/min., but top rail doesn't kick in until about 6000rpm?

look up sae outlaw in the US.they do a billet rail with an id about as thick as your little finger.Injector flow rates are either measured with the bosch standard fluid or fuel.the flow measurement of the 2 is quite different ,they are the same injectors as a gixxer 1000,which flow the same as gen1 busa injectors.

Sincerest thanks Spam,
Just saved too much money on the fuel rail.
Question:, Is it possible to piggyback, an injector driver wire with a 2nd, say for example, running into an FJO Racing 4 channel low impedance injector driver box, so, in effect, using the BBS, could run the 4 upper (secondary) injectors on the the K8 rail as well as 4 RC injectors into the airbox? Note: This is a question, not "advice required".

thats one for the dyno tuners out there to answer.
