I have been runing the Evens waterless coolent for the past 3.5 years in 2 bikes. First bike was a CRF450X. It wasn’t to bad but would get hot riding with Murph and Tim on there tracks. So got some Evens. Never cooked it EVER EVER again and never put a drop of coolent in it. I even cooked the clutch without cooking the motor once. New clutch was needed. I put 300 hrs on that bike with the Even’s coolent.
2nd bike is my KTM200EXC. Again l run normal coolend untill again riding with Murph & Tim. Cooked it in a creek track. I have put Even’s in it also and have never cooked it again and l am giving it a good workout in the creek tracks and at Stoction sand dunes in the soft sand.
I run the Even’s NPG’R and buy is from Bert Flood Imports, Vic. http://www.bertfloodimports.com.au/
It cost about $170.00 delivered for 4L of prep fluid and 4L of Even’s waterless NPG’R.That’s enough to do 2 bikes easy with spare coolend left over.
The coolend is only $50 but the prep fluid is expensive. You only need to prep the bike once. After that you just need coolent if needed after damage as long as you haven’t added any water to the system.
Yes it is does cost a bit but is way cheeper then a engine rebuild.
Just my thoughts and experience.
