Perfect
Nice engine flush that’s just right for the bikes - Good quality prouthat is quick and simple to use, helps take out old oil from all around the engine before the drop (always drop warm oil anyways) Good value monies - would like to see a bundle option.

Cleans the engine out perfectly.
Some say that if you change the engine oil frequently you won't need to use an engine flush, this is absolute nonsense. I have been in the motor trade for 45 years and know full well that using a quality engine flush keeps your engine as clean as it can be kept. This product is designed for motorcycles with an oil fed clutch assembly so can be used with confidence. Highly recommended and happy to award 10/10.

Does what it says
Why did you choose this product over others?: Liquid molly has a good reputation, not used before but it really did do what it said, would definitely use again on next one

Seems to work.
Just changed the oil in my Honda Goldwing 1200. Noticeably smoother and quieter with a decrease in idle but its hard to tell if that would simply happen after an oil change anyway but it certainly hasnt done any harm. The manufacturer states its suitable for wet clutches so I will update should I start having any problems.

Great product 💪👍
I tried this yesterday on my Suzuki RV225 and effect is amazing, for one liter of engine oil it's around 80/100 ml of engine flash. Brilliant product 👍👍
