Radiator Cap

I just took the sticker off of mine, but I like that mylers earless cap! At 23PSI it is a higher pressure rating than the stock one... FWIW.
The stock one is 1.4 bar is 20psi and boils at 109 degC or 229 degF.
1.6 bar is 23 psi and boils at 113 degC or 236 degF.

Mine occasionally bubbled out and dripped fluid onto the pipe and I could smell it. It was always only in certain situations and always reproducible.

The cap in combination with only filling the coolent to the min line and haven't seen the bubbling out since.

I also used the opportunity to pour in Motul Factory line (silicate free as per bike care instructions)
