Hi , just put the engine back in my 550 after doing the transmission , got all the mounting bolts in and nipped up , when i tightened the rear upper bolt ,[ m10 x 280mm long] , striped the thread !!!! didnt over tighten it, but knew it looked a bit knackered when i took it out ,anyone know the thread pitch ? looks to be 1.00 or 1.25 .
cant source one anywhere ! so i was thinking of buying some 10mm bar and m10 die to make one . do you think it matters whether i make it 1.00 , 1.25 or 1.5 pitch
cheers Paul
