Very quick question, NSR150 SP

[guangwei]

Eh, only recently checked coolant, realise coolant ran out completely. Do I need to dismantle everything and bleed it to the main mixture like the 2T oil when I refill my coolant?

Just top up, rev abit to blow out the bubbles and cap off. Check for leaks.

If the coolant ran out completely by itself, there is a leak. Get a mechanic to check it or you risk piston jam when the temperature gets high.

 

Avoid just topping up, because the coolant is not supposed to deplete.

You can check for leak by looking into the gearbox glass sight hole or into the filler hole. Milky oil means oil mix with coolant. High exhaust smoke/vapor could mean water entered combustion chamber, bike could be running poorly.

 

Left unattended could cause cylinder head warp and or gearbox rust pitting and high wear. Recommended to bring in for service if any of the symptoms occur.

EH I donno, theres no leak in the tank, however sometime while riding, I do feel something cold hit my leg though its a hot and sunny day. (No rain) My guess is theres holes in the radiator.. What do you guys think? I just serviced my bike about 2month ago, and they just top up my coolant.. but now its depleted when i check it last week

check 2T oil cap.. maybe your 2T old one or something. top up a new 2T.
