Hi The head gasket blew on my VT 750 and I would like to avoid splitting the case. Is there a way to flush the crank case? The bike only ran for about 5 min before it was shut down and was not driven. The coolant didnĀ“t have time to even mix with the oil. If I do need to split the case do you know an easy way to remove the clutch lock nut and to hold the fly wheel without purchasing the Honda tools?
