Hi guys,

New to trials. I have txt 280 pro.

I started bike, then rode it on gentle throttle / low speed 1st & 2nd gear. Within 5 mins the cooling fan came on and stayed on continuosly until stopping the bike.

Is this normal?

If not how do i check coolant level & how do i check the water pump ?

 Better that the fan runs than not. Pull the tank to get to the radiator cap.

Had a quick look into radiator.. Its only got water in by looks of it and its a bit scummy..

I took cap off & started the engine, the water is pumping.

I will remove and flush the system and clean the radiator.

The fuel was what came in the bike, so i will put ne fuel in. I was going to run 60:1 fuel mix maybe 80:1

Ps thanks for 'you tube' info

Just take on of the hoses of (when cold) and let it drip. Put it back on and fill with coolant. Dont mess with the torx gold colloured thing in the pump.

 

The pumps do go bad, but they will leak internally, so your oil will come out milkey (if you have a side glass you can spot it).

Ok thanks will do this tonight

Thanks

Ive just flushed it, new coolant, new oil, good quality fuel & oil.

Its running much better... Fan on & fan off after a couple mins.. Not boiling water.

Ive just mixed. 200ml top quality 2t oil with 12ltr of bp ultimate unleaded.....

I cant do math... So dunno what ratio that is prob 50/60:1

I will google what 80:1 works out per 1ltr so i know for future.

And yes it does look like i need to descale rad...but i'll do that next on list.

12 L with 200 ml oil is 60:1 hope that helps

80:1 would be 150ml in 12L.

Stand by for correction any time soon lol.

Thanks... Ive not run a 2t since 2007.... 4t easier to run but harder to fix.

Just devide 12 by 0.2 and the answer is 60. So its 1 liter of oil on 60 liters of gas.

 

So the amount of gas, devide by the amount of oil (both in liters or mm or whatever).
