Water cooling system

[DrunkenMistake]

This, sounds suspect to me. But it aint like I do this shit for a living, so I might have just never heard of it.

Just saying what happened,
May not have been the actual cause but it seemed to do the trick.

Plug heat certainly changes temperatures on a two stroke. I guess it could have a similar effect on a four banger.

Wouldn't have thought so at idle or just above though.

If the gap was tight enough it'd get hot, but the plug would shit itself long before the header glows red wouldn't it?
Maybe.

Would start with that, my old Hyo 650 done something similar, the front pipe did not glow red however but it was getting silly hot,
Front plug was rooted, I dumped the coolant and changed the plugs as part of a service and it seemed to fix it up,
A new Thermostat wouldn't hurt but I would start with the easy stuff before spending money where it's not needed to be spent.

A mate also had a similiar problem with his kwak, he had less than 1M ohm on the plug that was related to the cylinder that was glowing the front pipe.

I just put two brand new plugs on it previous to this happening

Could still be a faulty NEW plug

Always recheck your own work as a start. then check the basics. The flangedoodle actuator valve rarely fails.

I was a mechanic for too long and manufacturers usually build reliable stuff despite the foil hat wearers whinging.

And never run a motor with no thermostat, poor advice.

it can even run too hot due to this, there is some research for you.

Even in the race cars i worked on we ran a thermostat,At the least if it dies and you are stuck cut the centre out to allow some restriction of flow with the outer ring/flange.
