Yes the heat shield was originally planned and was put on before the carbs.
I have 38mm carbs from watercooled model, and to fit these I had to replace outer carb boots with another set of inner ones (to make for slightly different spacing), that alone wouldn't be a problem - actually the shield was made according to the actual carb spacing, but fitting 38mm carbs into 36 mm boots made them expand too much which left no space for the clamps.
So the shield had to go.
I'll think about another solution - maybe two smaller shields - the one I had was touching the oil hoses.
Or maybe one day I'll get me a flatslides or Yoshi heat sheild/airbox.
Anyway if anyone's curious here's the short spec:
91 GSXR 750: frame, oil cooler
90 GSXR 1100: oil hoses (only metal ends, original hoses replaced with stainless steel braided PTFE ones)
92 GSXR 1100: tank, seats, grab rail, rear cowling (to be modified), Devil exhaust system
93 GSXR 750W: carbs (dual BMC air filters), swingarm, rear brake
99 GSXR 750: clipons, switches, clutch lever, front wheel (Hayabusa spindle)
99 GSF 1200: main loom (shortened and modified to suit), CDI, horns, rear wheel, carb boots
00 GSX 1200 engine
01 GSF 600: sprocket cover (mechanical clutch release, one off sprocket nut with speedo rotor)
01 GSXR 750: front brakes, top yoke, headlight, front loom, mirrors, front mudguard
02 GSXR 1000: front forks (one off bottom yoke and stem), rear shock absorber (one off adjustable top mount), headlight/cowling bracket, clocks, front cowling (to be modifed)
Thank you Mr Suzuki for the "lego" toys
The carbs are set basically stock for 750W donor but with 155 mains.
The plugs look good, and it pulls cleanly from the bottom to the top.
No dyno yet, and some further jetting/setting up to be done in the future.
Don't know the consumption also, but it doesn't look to be extremely thirsty.
