    2018 Vmax with Voodoo pipes, tune, and air box mod.

    Hey everyone, I'm not sure if I should be concerned about this or not. This is my first Vmax so I don't know the quarks of this engine and what is normal and not. I had it tuned by Guru and the tune is great. I highly recommend.

    My concern is that I have coolant leaking from the weep holes at the top of both right side cylinders upon starting cold and then after I run it hard when warmed up. Has anyone experience this before and should I be concerned? It only has 6000 miles but they are hard miles. On my 3rd tire :)

    I have gotten info from Guru on this matter but just thought I would ask the community as well.

    He said "The weep holes on the Gen 2 are for the Spark Plug recess in the top of the head. If there is anti freeze leaking from it, it has to be dripping into the recess from somewhere else."

    I'm just curious if anyone else has experienced this and if I should bring it in for warranty work. Yamaha told me as long as I didn't open the motor then all work is covered.

    Pull the right scoop, and check the radiator cap, or the hose for the expansion tank. Everything to do with coolant is on the right side, like the gen 1s. Might have a loose clamp or something easy.
