Coleman Posted October 28, 2022 Posted October 28, 2022 Hi , quick question, without stripping the engine down how do you know what size gudgin pin your engine has I have a gsx 1100 ef grime 86 I have bought a 1260 bore kit but would like to know what size I have as there seems to be 18 or 20 mm I can swap the kit if it’s wrong ( 20mm ) it’s because the engine runs fine so I’m waiting to fit the new pistons , thanks Quote
