Your engine is quite a bit different than the roundies ... your head has 4 valves per cylinder, unlike the "other" which only has 2 valves per cylinder - I think they started making your motor in 1980 ... the 750 you have there is the grandfather of the present day gsxr motor - and it will get up and run when tuned properly. 8)

TSCC - stand for Twin Swirl Combustion Chamber - by the way ....

The "80" model 750 not only were the first of the 4 valve heads, they also had a plain bearing crankshaft, instead of the roller bearings. Does anyone know what the last roller bearing Suzuki was? I know the "86" 1150's were the last big Suzuki sport bike with them.

so far there is not a "last", the two strokes still use roller bearings.
and in four strokes the GZ 250 street bike uses roller bearings.
and the LS 650 savage uses roller bearings.
