Suzuki Epicuro 150 cc water cooling

ever tune it up, every 60,000 miles, this decade?
yes?
cold fuel is hard to burn, and bad spark is cause.
tune it up.
spark parts never last the life of any engine.
nor work cold , and damp, when old.
oldest cause on earth.

spark plug
engine oil level check
don't ride in low gears for long times

nag spin ang motor engine ko pero ayaw mg start, maitim ang spark plug then amoy gas yung lumalabas sa muffler

Check that your engine oil is clean(not contaminated with water). If you pull the dip stick out with oil on it you could put the oil coated dipstick into an open flame (lighter) for 3-5 seconds if it pops or crackles its wet.if it just smokes a bit its ok. A cold engine will do this fume-steam thing if the humidity is right.Once they warm up it usualy turns nearly clear.Make sure the bike is not exposed to rain, or cold to heat transitions.Some water from the tailpipe is normal,all gas engines can do it.If oil is dry and you dont have water from a cooling system dissapearing,(yours is air cooled) your probably ok.

my epicuro 150cc overheats. what's the common reason behind this problem? please help!

hi buddy its
1500mls+filter change
1300mls normal change no filter

Run the engine and look at the header tank , is there lots of air bubbles coming back out of the water if is then the head gasket may have split and that is down to either a can of Radweld or a strip down repair

If the radiator is not uniformly hot them I would go for that as your problem

Normal operation is that the engine starts the thermostat is closed , engine block heats up and opens water starts to circulate around the block

So to check that you need to fill the radiator with cold water run it for a few minutes check the bottom hose it should be cold

The stat opens and the bottom hose should get hot as the water from the block is pumped into the radiator for cooling.

The radiator should get hot all over and the cooling fan should kick in when the sensor hits the over limit stop.

If that does not happen then get someone to remove the stat altogether (It is only there to get the engine block warm quickly in cold regions )

In which case the bottom hose should go from cold to warm to hot

hi there ,,havent tried these guys yet m8 ,but try the downloadable wiring diagrams ,,if they do them 4 your bike,, try this www.repairmanual.com this is a downloadable manual site,, cheers

Have you noticed whether this happens more often when the scooter hasn't got as much fuel in the tank? (e.g. sloshed around so not enough is getting through the pipe) Next time you fill up, put a Fuel additive such as Redex in the tank with it.... and maybe also put something like Slick 50 in with the Engine oil, then see what happens from there.

Hi! My friend and I have experienced similar problem with each of our Suzuki Grand Vitara 2000 (his) and 2002 (mine). He discovered (two years ago) that cooling the "camshaft rotary sensor" by pouring (normal) water (which I also did just last week) and it works to start & run the car until the next pull-over. You have to redo pouring water if you stop the endine and does not re-start. But this may be just an emergency solution wherein you have to let the car be serviced by a mechanic.
