FJD Posted September 10, 2018 Posted September 10, 2018 I am in the process of building an GSF engine for high power output, and would like to throw in bigger main bearing studs. Original are M8x1.25, i would like to have M10 size chromoly, which i´m pretty sure the cases can accept. Anyone knows a source where to get them, or an engine that has the same sizes original. sizes are: 8 x 125mm 2 x 65mm under head length Quote
Gixer1460 Posted September 10, 2018 Posted September 10, 2018 1 hour ago, no class said: APE do big case studs They do but they are still M8's. Bigger ain't needed - the crank doesn't 'walk around' like the GSX ones do! Quote
no class Posted September 10, 2018 Posted September 10, 2018 you can probably get some done through ARP . whatever tickles your fancy . Quote
colinworth79 Posted September 11, 2018 Posted September 11, 2018 How much you after, lots of people on here have 300hp plus turbo's and just use the ape studs. My - 1216 turbo lump used stock suzuki bolts for 8years with no problems. Used ape with the current 1340 turbo lump. Quote
