worked it out yet?

Why - Please explain? As the whole point of an in-tank pump is it doesn't need a return?

Yeah sounds like its FUBAR'd ! _ Try this....... https://www.Eblag.co.uk/i/143218994785?chn=ps&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=143218994785&targetid=876284534867&device=c&mktype=pla&googleloc=1006733&poi=&campaignid=9446077381&mkgroupid=98366966800&rlsatarget=pla-876284534867&abcId=1139356&merchantid=7328234&gclid=EAIaIQobChMI6uL4qJP-6AIVmK3tCh255Q1FEAQYBSABEgLur_D_BwE Assuming the thread IS 1/8 NPT ! ! !

SMIDSY accident waiting in the wings!

Thank you - i've edited my post!

Don't 750's have 6 speed boxes anyway - obviously not close ratio though? As there were lots of 750 race bike classes, I would have thought suzuki kit gearboxes would be available and cheaper second hand?

4 out of CDI - Orange / white = 12v + (single wire splits in loom to both coils), Black / white = ground / earth to frame / chassis, Black / yellow = Coil 2/3 & White = Coil 1/4. 5 out of pick-up case - Blue + Yellow and Green + Black are pick-up signals (two pick-ups) and Green/yellow? = Oil pressure switch signal to dash. This is for Slabby motors, Slingshot motors are similar except one pick-up is deleted so no Green + Black wires present.

They are usually fairly indestructible - are you sure its 'goosed'? I think the thread is something like 1/8" NPT so any water / oil temp sender of that size should work although matching the resistances could be hit or miss? Have you tested the gauge as that is more likely to fail?

Interesting picture - shows RH handle bar but reversed ! ! ! The front brake switch is a black rectangular plastic 'box' with rounded ends held to lever bracket with two screws - it has a little slide that slots into the lever. As lever moves the slide makes / connects contacts within the switch. It should have either two contacts at one end or a couple of wires, sheathed in plastic with bullet connectors on the ends. What main light switch is fitted? Is it off - side - main or off - main? Obviously if the latter the main light will switch on and that will be dip, The high beam switch should cut the dip when you select high beam. For Parking light a better term would be 'Stand' - if your bike does have a switch on the side stand, it is a safety device that cuts the engine if you select a gear with stand down - can be a PITA so most people bypass them!

Wouldn't it be best to ask Nova? As far as i'm aware the 'M' GSXR 11 box is swappable with a GSF, but don't know for a fact!

Have you got a leak ? Never seen anything drink that fast standing still

Whilst many turbobikes have been built around GS1000 / GS1100 / GS1150 (or GSX1100 / GSX1100EFE) whilst strong, their press together cranks are their weakness and require rebuilding, welding new bearings for safety as even low boost can move them. Also there is the oil supply issue which, whilst can be improved with 750 pump gears, it doesn't provide excess pressure which would be an advantage. A slightly reworked GSXR 1100 or GSF 1200 makes a good base for boost, easily safe to 250hp in stock'ish form - forged pistons are a good upgrade whatever boost you plan, rods if you want to go better than 250+hp and personally I'd choose EFI for simplicity of plumbing and control potential - its nearly as cheap as a decent rack of new carbs!

Search me ! I don't run an airbox!

Sounds about right although the Red ones aren't 'overflows' they vent the float bowls or no fuel would flow! If they were overflows, the way they are routed, neat fuel would be pouring down the bores before any dripped out of the pipe ends! They normally connect to the airbox!

Gasgacinch for both - copper head and aluminium spacer base, worked fine for me!

Try coming up with another shape that has 4 outlets in a line one side and 1 inlet the other (often not in line) is compact and easy to weld or cast? I've seen tube plenums but cutting radiuses and bevels is time consuming and never perform significantly better so why bother? I guess you could try 3D printing one - how it would withstand heat and pressure could be an issue?

And in Spain of all places - over cooling is pretty unlikely unless you are fitting a stupidly large, oversize cooler!

You just have to look at how the fuel gets to the cylinder from the carb - it gets centrifuged out through the turbo then dumped into a box with generally poor airflow paths, make a couple of 90 degree turns and it gets to the valves - hence why a wet mixture pre start is needed. Just use the 'right' carb and forget about complicated add-ons. Good turbo the T2, that was my first build - 1186cc, 10lb boost = 210hp S&S Shortie Super E. IHI's are good as well - i'm sure there was a 750 turbo build in the old Turbobike magazine - i'll dig it out and scan it, but I seem to remember it being a blow through!

Why would a CV carb be fitted with an accelerator pump as by its very function, it won't allow more air to be admitted to match fuel flow? And why faff around with primer pumps etc - that's what choke systems are for!

In theory you may be able to use a CV carb - they are designed to regulate airflow based on actual engine demand and not throttle position but how they would react once boost overcame vacuum would be anyone's guess! Due to the tortuous inlet tract of a draw through you usually need yo flood the plenum with fuel to get the damn things to fire up so a carb without a accel pump will be at a disadvantage IMO. Flat, round or square doesn't make much difference except on hi boost applications as the actual airspeed pushes on the slide 'wedging' it open - it's why you need strong return springs or a twin cable throttle to pull it shut!

Sean is a very convincing salesman! And I am a friend LOL!

You'd never guess . . . . . https://oldskoolsuzuki.info/forums/forum/4-general-chat/ LOL! If this is like the 750ET - you've got a gear output 'switch' behind the sprocket cover, wires up to the instruments which has a series of bulbs - one for each gear and another for neutral. If some are lighting up they have power (the switch provides the earth) so bulbs could be blown? Wires broken? or switch terminals dirty?

Draw throughs are pretty 'old tech' these days - nothing wrong with that but they are hard work to get them running well. A 750 is quite small and to find a suitable turbo will be tricky as most info will be for litre / 1100+ sized engines - the turbo must be able to be fitted with carbon seals to minimise a 'smokey joe' on the over-run. HSR40 may be ok for a 750 - the larger 42 / 45 / 48 HSR's, 1.7/8", 2.1/8" S&S's are definitely better with the bigger capacities up to 1500+ cc! The HSR's seem to work better for a road bike - they seem to fuel better - S&S are great when drag racing. If I was to do another one, I'd junk the carb and fit a throttle body in its place and build injectors into the plenum to fire directly down the inlets, add a BOV on the plenum as a priority valve and allow use of a modern BB turbo and decent accurate fuel / ignition control - 'old skool' looks but with decent manners - lovely!

A company that does anodising / plating / chroming should be able to strip any previous dyes through the prep process - the biggest difficulty is finding someone having a bath / tank to fit a whole frame in and submerged in one go.
