Roketa 2007 Touring Bali 250

[4pergal]

I have a new Roketa 2007 Touring Bali 250cc that runs hot ( according to the gauge), but does not overheat or stall. Has anybody experienced temp gauge that, after engine is warmed up, always runs in the hot, red zone on the gauge? The indicator might drop out of the red zone a small amount. BNScooter.com, the dealer I bought the scooter from, told me that they did their own test and found that many of the temp gauges are not accurate. Yet, I have never observed the cooling fan come on!! BNScooter.com also told me to check the fan wire connection. That did not solve anything!! I took delivery of the scooter on 07 Aug. 06 and I am still waiting to feel comfortable to start utilizing it for transportation without burning up the engine. I have only rode it around a local parking lot by my home up to about 25- 30 mph. Even when it is just idling, again the temp gauge will go in and out of the red zone. Any advice would be appreciated.
Thanks

Check this forum out. Instructions for filling the radiator.

Also, ride the scoot until warm, turn it off, then just turn on the key and see if you can hear the fan running.

If it is really running that hot, you should be able to tell. Try feeling the radiator after you shut it off. It should be hot. If it isn't, you may not be circulating water. Possibly a thermostat problem. I would pull the cap and see if it is full. I'm wondering if it is just the gauge... Another thing you can do is hot wire the fan and see if that brings the gauge down.

Thank you so much for your advice allengrota and russ55. I will try your advice tomorrow.

All of Allen's ideas are good ones. I am suspicious of the thermostat quality. Because my scoot takes several KMs to warm up to operating temp, I wonder if the thermostat has failed in the open position. Once warmed up, the gauge fluctuates between 1/3 - 1/2 as the fan cuts off and on. Could be it is just the nature of the beast. Did you read the post above this? You might try the "Dots" or "Crayons". Stan has "shot" his cooling system at several locations with a temperature reader and has gotten normal readings.

I've tested the thermostat and it passed just fine. Out of curiosity, I even ran without for a couple days. The only difference was that it took a little longer to warm up, but the operating temp was exactly the same. If you are running under 3/4 of the way on the gauge, I'd say you are in good shape. Mine started to climb over night, and has remained at the high end of the gauge since, when at operating temp. I fully expect to find that either the sending unit or the gauge are just crap. I want to lean toward the sending unit because of the change, since a gauge is generally just resistance driven and the resistance is derived from the sending unit. I do need to take some physical readings of the coolant, which I have not done yet. Stan
