Thought i would introduce myself with my Powerscreen build 
It all started when my brother brought this 1100f for it's engine/carbs to fit into his 86 gsxr1100g slabby. And for putting his gsxr back together,he gave me the gsx rolling chassis and his Knackered 1052cc engine(Flowed head,kent cams,etc).
Now,I also own an 89 Gsxr1100k with 90 Gsxr750L usd front end and back wheel,but it is getting a real chore to ride the old girl(slingshot Gsxr's have really cramped riding position),as,my hip and back are totally knackered(steel plates and broken bones from a bike crash in 95).But i really miss riding my bikes
So i sat on the gsx and was shocked at how comfy they are(plus the powerscreen is ace,up down,up,down
),but just a tad on the heavy side,so I looked at my gsxr and looked at the gsx,then hatched a plan to combine the two.
This will be the gsx frame,swinging arm(may swap this for the 11k arm,it is slightly lighter),rear brake assembly,switchgear,elctrics,airbox and bodywork.
And the gsxr engine,carbs(bst36ss),airbox rubbers,usd front end,slingshot curved oil cooler,braided oil-cooler hoses and 5.5" rear wheel.
With some aftermarket risers,flat pull-back bars,R6 1/4 turn throttle tube,and the cable clutch conversion(I prefer these,as you get more adjustment and it weighs less than the hyd. setup) I was running on my 11k, home-made fish shape sprocket cover,srad600 clutch lever assembly and cable,Micron gsxr750l 4-1 headers and link pipe,One off end can,Gsxr400/Rgv250 mudguard(fender),Pretech six pot calipers,Hel brake hoses all round,Tl1000s 14mm master cylinder,Brembo reservoir, cnc levers and a hagon gsxr1100ws(or sv1000 shock).
So far I have swapped the front end and rear wheel.This went together surprisingly easy,as the gsx uses the same length stem and the same size bearings as the gsxr's. And the back wheel slotted straight into the gsx arm,even the torque arm has plenty of clearance for the wider 180 tyre.
I ran into a slight snag on the rear brake,as I run a 220mm rear disc/hanger from the slabby 750/1100's,but wanted to keep the top mount gsx caliper and torque(Gsxr torque arms bolt to the frame and calipers are bottom mount),but the gsx caliper is a different bolt spacing to the bottom mount calipers(I use an sv650 one on my gsxr).So I will have to go back to a 240mm (slingshot/bandit) disc and the gsx caliper hanger,not a big problem really.
Just doing the front and back end swap,as saved me 30kg.The top yoke(triple)and bars weighed in at 5kg alone,which is alot compared to gsxr one. That weighs in at just over 1/2 a kg and that includes the top yoke,risers,bars
It will take a while to finish,but hope to get out on it before winter(touch wood).
Incidently my gsxr is going back together as well,after the frame and the new shorter 88/89 gsxr750j/k swinging arm are powder-coated.I am re-building the knackered(rings had gone and was down on compression,plus chucking oil out the exhaust) 1052 slabby engine and taking it out to 1109cc with bst38ss carbs.This was just the excuse i needed to give her a re-build
I may even stick the 1109 in the powerscreen
My Gsxr1100k before the strip.
My new Gsx1100f before the strip
Where the gsx1100f engine and carbs going.
Sans engine/carbs and measure up for wheels.
New running gear fitted
And Yep,my dining room doubles as my garage(why the floor is rough,but clean,I must by some tiles,one day),just one of the joys of being single
