Suzuki Engine

From the GN250 workshop manual ... "GN250 models use SUZUKI's unique TSCC engine design, which is internationally acclaimed for it's durability and performance. TSCC describes the heart of the engine, the Twin Swirl Combustion Chamber. What the TSCC engine series does better than conventional 4 stroke engines, either 2-valve or 4-valve is improve on the two major factors which affect engine performance, charge burning efficiency and intake charging efficiency."

This TSCC engine design has been used in other Suzuki engines, like the famous GSXR 750 and 1000 sports bikes. While a single pot engine cannot approach the efficiency of larger four cylinder versions, it is known to be a highly efficient engine design.

It should not be too hard to improve this sweet little engine to a bit more than it's rated 22 HP. Maybe a free-flowing exhaust and bigger jets or carbie. I'm hopeful to see over 25 HP, and maybe 30 HP from this little beauty. When you consider the Ducati 350 Desmo had only about 30 HP and weighed 175 odd kgs, my Suzi cafe at only 125 kgs should compare quite well.
