Suzuki GSXR 750 L Slingshot 1990 Barn find restoration project.
Been in storage as far as I can tell for over 15 years.
In good condition for its age and there is a box with chain and sprockets and carb jets?...
We did start it up and it runs but was spitting flames, I was told probably down to old fuel in the carbs. It was running fine and MOTed when it was parked up.
The indicator that's not on it is in the box of bits so its all there and complete.
V5 is present, I did fill it out as I initially thought about keeping it but realistically I won't have time to use it if I did.
Although this model looks very similar to the previous '89 model many changes were made. The 1990 Suzuki GSX-R750L was considered possibly the best of the oil-cooled GSX-R750 models. The 1990 Suzuki GSX-R750 featured changes to the engine, suspension, body work, brakes and chassis. This was the first GSX-R to be fitted with inverted forks as standard (USA models retained the conventional forks until 1991), and returned to the bore and stroke dimension of the original long-stroke engine.
The engine returned to the 749 cc engine bore and stroke dimensions of the original long-stroke engine but still maintained the 13,000 rpm redline. It now featured new conrods, lighter pistons, smaller valves than the 1988/89 engine but larger than the 1985-87 engine and used larger carburetors. The new Mikuni model BST38SS “slingshot” carburetors were 38 mm diameter and featured an additional high-speed circuit (circuit was blocked in USA models) and the slide breathers were now divorced from air box. The exhaust system was also changed, gone were the dual silencers and replaced with one stainless steel silencer on the right side and the transmission output shaft was lengthened to accommodate a wider wheel. A new curved oil-cooler design with a large capacity oil pump and oil lines (attached to the oil pan similar to the original 85-87 engines) were installed. Horsepower was up to 115 hp at 11,000 rpm while weight was down to 193 kg.
The frame was changed for 1990 and used some of the features from the '89 GSX-R1100 frame with the rake was now 25.5 degrees and wheelbase 55.7 inches (1,410 mm). The front suspension now had 41mm inverted forks, the triple clamps (yokes) and handlebars were changed to accommodate the new forks. The rear suspension featured a new shock and swingarm, the rear shock now had a remote reservoir and damping adjustment and the revised swingarm now featured cast ends for the axle adjustment. With the rear wheel widened to from 4.4 inches (110mm) to 5.5 inches (140 mm) but the tire size remained the same. A non-adjustable steering damper was added which attached from the left frame rail to a clamp on the left fork (US models did not receive the damper but the frame had the tapped mounting holes). The rear sprocket carrier and sprocket changed from a five to a six-bolt design. The front brake rotors changed from a cross drilled hole design to a slotted design.
The body work changed slightly also with the side vents becoming less rectangular and in a slightly different position. A new fender was also used with the inverted forks (except US).
Many thanks.
