The engine is brand new but needs a rod, I have been told that I cant put a 5.5 conrod in it as the big end bushing is a different size to the Gen 4 bushing. I could buy a 5.5 crank as well but would rather get out of it as cheaply as I can.
Thanks
nope you can replace a gen4 with gen5.5 I'm about to if Mark at massive hadn't run out of crankshafts..
grizz1...yup mine has ovaled just like you said..checked it again and the end of the pin is 4.82 x 4.88...definitely oval...I wanted to bung a 5.5 in there anyway..bummer is I am on holiday from work..weather is perfect..track is all fixed..and I don't have an engine..
