Water cooling system

[Confrontation]

I was warming up my bike this afternoon , I had adjusted the idler so the bike was at 1500rpm (I need to get a tune up) , I came back to the bike to see the front exhaust was glowing red hot also the radiator was warm on one side and cold on the other.
The thermostat sensor is broken and I'm getting a replacement.
The fans were also not working (im guessing thats to do with the thermostat) and the coolant seem to be in the coolant tank.

Guess Im wanting to know is it all to do with the thermostat sensor not working?

fuck the sensor. rip the thermo out. maximum cooling. all the time.

Glowing red hot header, is possibly a sign that the timing is fucked. It shouldn't get that hot without a very serious thrashing.

Could also be a sign of something much worse, but get the timing checked before anyone tries to pull the head off.

Not your best advice there Pikey.

Running a motor too cold, can fuck it big time. A Hyosung in particular.

What could be worse?

Burnt out valves, skipped cam timing. Bad stuff.

Ignition timing on your bike shouldn't be adjustable, but those crazy Koreans have made stranger decisions when desiging the bike.

Before we get carried away, how mechanical are you?

Argh! do not listen to Akzle. bloody Waikatoians don't know one end of a motobic to annudder.
I've just been through a very similar thing with the wife's Nonda.
Do replace the thermostat.
Do take the radiator out and have it flushed.
Do check the temperature actuating switch screwed into the radiator.
Do have your radiator cap checked for holding pressure and if suspect. Do replace it as well.
I was told that this bike had a head gasket problem and the engine needed to come out and the heads removed and gaskets replaced, approx $1500-2000.00 worth of work.
Just had the carbs properly balanced, air box fitted correctly and all things that were a little bit wrong returned to speck by George the Mobile Motorcycle Mechanic this afternoon.
Bike is running like a Swiss watch now and I'm sure will not give us anymore problems.
So if you are up to it try doing what I've just done, otherwise give George a call on 021837697 and he'll do it for you.

Im not overly mechanical , But I just put a new piston , rings and second hand head (with valves already in) on the motor over seen by a retired engineer and with the odd 2 cents worth from an engineer at work who just done the timing for me.
It has had 3 short 10 minute trips before seeing this , one being 6am this morning.

Where is George located?

The plot thickens.

Was the piston and head you did, the one with the glowing pipe?

Yes it was

[Drew]

Yes it was

Mmmmkay.

I would probably flag looking at the ignition timing then, and whip the rocker cover off to check the cam timing.

The rough running could be caused by advanced exhaust valve timing, which would also cause the red hot header.

I will look at that , But as the timing has just been done and had 30mins running , what would throw the timing out?

right behind you.

Running a motor too cold, can fuck it big time. A Hyosung in particular.

a hyosung you say.

fuck that. bin it and buy a real bike.

Not being timed right, (even mechanics get that wrong from time to time), or a camchain tensioner not being adjusted, (or unlocked after assembly) properly are the obvious ones.
