290 Posted June 2, 2022 Report Share Posted June 2, 2022 (edited) I mistakenly put heavy 4 stroke gearbox oil into my 2015 Sherco 300 trials...I ran it for around 10 minutes until noticing the fan wasnt coming on and realised my mistake with the oil. I have just replaced the water pump seals and axle and refilled the coolant and light gearbox oil. The fan is still not kicking in and its blowing loads of smoke out of the exhaust....also the compression seems much higher....Any ideas what the problem is? Thanks!
