1000 73.5mm overbore kit

[1948man]

Maybe this is it? 1100g has 66mm (6.6 cm) stroke. Formula for volume of cylinder is Pi times r squared times stroke. Figuring 74 mm (7.4 cm) diameter cylinder, that would be 3.7cm for the radius of cylinder. So
Pi(3.14) x 3.7 x 3.7 x 6.6=283.71cc for 1 cylinder. Four cylinders would equal 1134.85 cc.

73.5 mm pistons in a GS1100G makes 1120 cc

Yeah, I guess my mistake was figuring a cylinder bore of 74 mm when it would probably be more like 73.55 mm for a 73.5 piston.

I believe that you got it!
The stock dimensions of the Suzuki GS1150's DUH.
66 X 74=1135 cc's

Ed is probably correct with the 1120 figure with 73.5 piston bore.

Did this 3.5 mm overbore.

I recently installed this kit. The 140$ one and there was $28 in shipping but the kit came from Japan in 4 days USPS. My bores were so pitted from sitting 25 years that they needed it. The liner is thin, but if you do bore it be sure to have the machinist re-grind an entry taper at the bottom of the cylinder. My man didn't and it took me 4 hours to get the pistons into the cylinders.

So has anyone bought these? Inquisitive minds want answers.

Did you read the post just before yours?

They don't seem to be available anymore from the original ebay guy.

They don't seem to be available anymore from the original ebay guy.

The inventory comes & goes. I got the last one of a batch, but they have been relisted.

Since eBay links do not last forever, if the above one is outdated, look up the seller and search for GS1000 pistons: cruzinimage_co

I'm installing mine into a GS1100G cylinder & using an 1100G D-port head. Probably a few weeks away from putting everything together, I'm still looking into proper gaskets and specs.
