Engine Radiator Maintain

I NSR150 SP engine radiator mantain. Normally Engine heat need water take it out of cylinder. And use radiator effusion heat.

That is, 

air need across radiator fin and take heat out. 

When radiator fin doesn't regularly and has gap between each fin. The heat will not effuse efficiency.

For example, below is used radiator. The fin has damaged by stone.

After maintain. The fin has more regularly than before.

Record for NSR150SP maintain and renew

Today is rear brake maintain.

NSR150SP rear brake switch has a spring connect to brake pedal, and the spring is hard to find. 

That is, I have a change got the 2nd source from Yamaha.
FZR150 rear brake switch can use for NSR. and the package include the switch and spring. 

Only one item need to modify is spring length need to reduce. 

You can refer to this picture. 

The connector is the same with NSR
