Bjørnar Eskedal is back with an update on his custom 373 cc inline-six. For the past couple of years Bjørnar has been building a custom inline-six using engine parts from multiple 1989 Suzuki GSX-R250 motors. Bjørnar has finished building the block, head, head gasket, billet crankshaft, and one of the camshafts. The completed motor features a 49 mm bore, 33 mm stroke, 12.5:1 compression, and 32 mm carburetors. Bjørnar is hoping to have the motor running by spring or summer 2026.
