One of the issues with the GPZ 9 is the fact they tend to run hot and after having a bimble out on her the other day I started to feel myself cook a little from the heat off the engine, anyway I was telling one of the lads at work about it and he mentioned 'Water wetter' he runs his ZZR 1400 on it and swears by it, by adding this to a mix of good coolant/anti freeze and using ionised water the properties of the water are slightly altered allowed it stick to the heated metal surfaces longer and therefore cool more efficiently, anyhoo you've probably all heard about it but if not

apparently it doesn't lower the temp per se but reduces hot spots which helps to bring the overall temp down, there are mostly good reviews on the GPZ forum so you never know

Re: Water wetter
Not heard of that but a mate who runs classic race cars swears by Evans coolant.
Have you thought about getting a thermostat of another bike that will be set to open earlier than the OEM item Kawasaki fitted on the gpz.

Re: Water wetter
Yeah one of the upgrades a lot of the GPZ lads use is an upgraded thermostat from 0.9 bar to 1.1 bar, trouble is I'm off to Scotland in 4 weeks and I don't want to start messing about with too much before I go, however I need to know its going to run right while I'm up the road, I'd never heard of water wetter either, well I've got 12 hrs at work later with nothing to do except a bit of internet research on it I guess.

Re: Water wetter
It does work, there's different brands that do a similar thing, but iirc it reduces surface tension and increases specific heat capacity, which in real terms means it has better contact with internal surfaces so heat can more easily be absorbed and conducted into radiators etc and the coolant can absorb more heat than normal fresh water. Hth.

Re: Water wetter
Do I also remember reading that, as it has a much higher boiling point, it doesn't expand as much & therefore does not add system stress with the usual pressure.?

That sounds like a common fault with a proven solution to me.Stew wrote:Yeah one of the upgrades a lot of the GPZ lads use is an upgraded thermostat from 0.9 bar to 1.1 bar, trouble is I'm off to Scotland in 4 weeks and I don't want to start messing about with too much before I go, however I need to know its going to run right while I'm up the road, I'd never heard of water wetter either, well I've got 12 hrs at work later with nothing to do except a bit of internet research on it I guess.
I would forget water wetter and other snake oil branded products IMO and go down the proven modification route that all other GPZ owners do if it were me.
Might be more hassle but should be easily possible to install and test before departure in 4 weeks. And I reckon if you go down the water wetter route you will eventually have to go the thermostat route in the end if you want a noticeable difference. Could save time and money by going straight to the proven solution.
