One thing that concerns me is the injector angle! They are very steep and looks like most of the fuel is going to hit the other side of the port / throttle body. Obviously with the std motor they would be downdraught and almost in the head - all the angles and twists and turns may cause fuel drop out? Although it would be ideal to get the injectors aimed directly at the intake valves it seems that less ideal injector angle usually doesn't cause any problems. At least if the injectors are reasonably close to the head. Based on my experiences I would prefer less ideal angle closer to the head over better angle further away (i.e. on back of the plenum). At WOT injector placement isn't very critical as long as the fuel ends to the right cylinders. Possible problems will occur at low rews when there isn't enough air flow to keep the fuel moving.

good to know.
i cant imagine it'll be a very ridable bike anyway, in terms of throttle control and idle.
not that im bothered as long as it fucks off in a straight line very quickly when i pin the throttle.

You'd be suprised about how rideable a EFI turbo bike will be - not like the all or nothing light switch draw through 'old skool' turbos. As Arttu says the low throttle air speed is the problem but that can be mapped so will fuel exactly right which helps a lot. Personally I would have stuck the injectors in the machined inlet pieces at an angle between 30 - 45 degrees to fire more down the port. But most things will work, its just how well or badly that is, has to be found out by experimentation.

head cooler fittings. decided to go for -8 rather than the -6 im running now. seeing as the pump outlet on the crankcases is the same bore as the -8 fittings.

That's exactly what I want to do so I can run the oil lines down the side of the engine ala 80's racers. I sent an email to Torques asking if this was possible only a couple of days ago. Only stumbling block I've come across is the (cheaper) coolers I've seen though are an10 - are you going for an10 or 8?

But the exit from the crankcase splits into two ie from -8 to two -6's to keep the pressure / flow up as standard. The above will just lower pressure but provide greater volume although still choked down in the cam cover drillings?

I would have had a long reply about how I was going to modify the cam link lines and run them from take offs rather than the rocker cover plugs...
But seeing as -8 stuff doesn't fit in due to the modified top rail / fuel tank / billet inlet things / because the 12 engine is taller than the 750 one, then there going back to torques tomorrow to be swapped for -6 ones which should just fit.

injector loom done. bit of coil wiring. the plate that everythings bolted on to. did some of the fuel lines today. fuse box with led's to tell you if the circuits working temporally bolted a sidewinder on, want to test the fi before i add the turbo. aeroquip socketless push on things. look nice.

bit more wiring done. de-latched the microsquirt connector. first pair re fitted. 2 down, 30 odd to go. coil driver connector with earth tag.

pick up tube return fitting left is pick up, right is return put in enough wiring to plug the laptop into it and put in some settings. can't fire it up yet due to some fittings being messed up (top marks to torques for sorting it out for me dead quick) fire up some point next week.
