gs1000 motor use gs1100 or 1150 parts?

[Guest]

If I get engine work done on a 1000 motor will it accept oversized pistons for a 1150 motor and cams? I guess what I'm asking is is the 1000 the same motor as the 1100 and 1150 just different bore?

Thanks,

The 1000 family is a 2 valve motor, the 1100 1150 family is a 4 valve per cylinder motor.

Orient express has oversize pistons and valves for the 1000 family.

The pockets on the pistons head are shaped for four valves and could clash with your two big valves, the 1150 ones also have larger piston pin hole diameter (20mm). There are bigbore kits specifically for the 1000.

the one exception being the 82 1000 Katana.

otherwise there are few crossover parts, the clutch basket used on the 16 valve 1100 is the same as the one used on the 1000G, witch is differant from the basket used on the chain drive 8 valve 1000's
