Engine Flush good or Bad

Hi guys,

I have only had a bike since October, so go easy on me

I have heard that using Engine Flush stuff for your motorbike is bad apprently.

Is this true?

I wouldn't use it myself. OEM filters and good oil shoult see you right?

But why is it fine on a car and not a bike? something about a wet clutch?

Some car engine oils can contain friction modifiers which will screw up a wet clutch, I guess it is possible that engine flush could contain these. This is why it's generally better to use a bike specific engine oil for bikes unless you know that the oil is OK for bike engines. For general maintenace there shouldn't be any need for an engine flush, as has been said a good quality filter and decent oil changed within the relevent service intervals should be fine. Personally I choose to do an oil change about 1k before it's due and generally change the filter with each change, just for peace if mind.

will screw up the clutch plates as its a wet clutch (uses same oil as gearbox unlike a car).

If you realy feel the need to flush your engine use some cheap engine oil as the flush . Fill it to the level . start your engine just to warm the oil, then drain and fill with your normall oil. Job done ..
But as said above if you keep your oil and filtfer change regular there is no need really

It's not a great idea on either a bike or a car, and simply shouldn't be necessary if the oil and filter have been changed regularly.
