Find a early 750 Katana head (the same as a 1988-1989 GSXR750 head) they are farely cheap add a spring/retainer kit with a aftermarket camshaft with no more then. If I was building a 1052 (the better GSXR1100 crankshaft) I'd use a stock 1127 cylinder and put 1mm oversize Suzuki 1127 pistons in it, add that to your 58mm crank and you would have 1137 AND still have next to stock engine temps. You have 5 gears, not six, this means torque is your greatest strength and if you build a engine with a narrow power band up top, you will get left at the light EVERY time. The head is where the horsepower is extracted and the easiest to get wrong. 1109 would be good and the low weight of the early GSXR1100 makes your bike a wolf in sheeps clothing to the innocent nubbie riding mommies latest gift. But becareful, with horsepower comes heat and less reliability. If you are much heavier then your riding buddies then you may want to add displacement to increase available torque. You can go MUCH larger but I used 1109 to keep the cost down. The 1340 (85mm piston) will bring your 1052 to 1316cc, the 1277 would be 1255 in the 1052.Īnyway, a simple 1109 using 12-1 compression is capable of giving 168-170 bhp measured at the countershaft. The 1052 engine does not give the same displacement per mm of over bore as the 1127, meaning.
