I don't recommend Water Wetter for the street because in 6 months the steel impeller on the customer water pump begins to show rust... I only recommend it for track use and when you return to street drain the Wetter and go back to normal coolant with rust inhibitors... I need help. I used water wetter not knowing it did not have rust inhibitors. I drained last week, after 2 years and had pretty signifigcant rusty water coating everything. What should I do now? What things do I need to address, thermostat water pump etc...? The bike is in pieces for winter maintenance so can not run flush run flush. I filled with straight antifreeze so as not to leave dry. What next? Thx Link to comment Share on other sites More sharing options...

It was that that lead to the cam drive in the VFR. Still that that VF is better looking than the first VFR ! Flame suit on ! Link to comment Share on other sites More sharing options...
Member Contributer BusyLittleShop Posted January 25, 2019 Member Contributer Share Posted January 25, 2019 Start with draining and wire wheel (Dremel) the steel impeller on the water pump back to new condition... fill with 50% 50% and monitor any new rust... then go into the thermostat...

Member Contributer TheLimey Posted January 25, 2019 Member Contributer Share Posted January 25, 2019 Citric acid is easily obtainable from any supermarket and will do wonders for a rusty steel part left overnight to soak in it. Link to comment Share on other sites More sharing options...
Member Contributer expvet Posted January 26, 2019 Member Contributer Share Posted January 26, 2019 If you have a Honda car dealer nearby the Honda Blue Type 2 coolant is the exact same formula as the Pro Honda HP Coolant, only the color is different (Blue vs. Green). In the event you do not here is the Amazon link. $22.00 a gallon including shipping. https://www.amazon.com/Genuine-Honda-Long-Life-Coolant/dp/B006YX9YZE/ref=sr_1_1?ie=UTF8&qid=1548514551&sr=8-1&keywords=honda+coolant+type+2+blue Link to comment Share on other sites More sharing options...

I missed ONE o ring when changing them out. Guess which one leaked after the next flush? And it wasn't a leak you could see. You'd just smell it as it must have been so small it aerosolized. Anyway, I replaced the O-ring, and when I pulled the knuckle the one in there was just crusty and awful. As were a couple of others I'd pulled before. I can't emphasize to folks enough, if you're tearing a bike apart for any reason, just change the o rings. They're cheap insurance. Especially for those of us with older generation VFRs that might have sat for a few years. Link to comment Share on other sites More sharing options...

Member Contributer MooseMoose Posted January 29, 2019 Member Contributer Share Posted January 29, 2019 All the knuckles and the thermostat housing for a 5th gen. The ones under the throttlebody are a pain to get to, so worth doing if you're ever working under there. I don't know where everything is on a 7th gen offhand, though. I haven't worked on that engine. Only the 800s and 750s. Link to comment Share on other sites More sharing options...

Don't even think of it. I'll try to find my post/review of this on another forum but remember that water is the most efficient at removing heat. I can't remember which glycol Evans is made from but it's something like 40% less efficient at removing heat. Bikes do NOT have that much extra cooling capacity. When I ran it for a weekend my ZX-9R got up to 250 degrees almost immediately after getting off the highway. When I switched it back over to water wetter and an 80/20 mix of water to coolant, it's back to normal. Link to comment Share on other sites More sharing options...
