    Question Water Box Removal?

    Hey ,

    Does anyone have experience or know if you can remove the waterbox on a 2up spark? We used to do it back when I had all my two strokes, it was pretty easy than. But with it being a four stroke and closed loop I am not sure if it is possible.....

    It's closed loop cooling doesn't have anything to do with the waterbox. You just unhook it and replace it with a pipe. Check this forums store they have Riva and Worx

    So you cannot just remove it? You would have to replace with something? Meen66, I will look into this....Thank you.... I am going to finish up my exhaust tomorrow with a straight pipe with two 45 elbows. I already installed high flow but this should give it a little more aggressive sound and maybe a little more bottom.......

    So why can you not just eliminate water box? Overheating?

    Well you cant simply eliminate unless your able to mount the sensor (o2. Exhuast temp Not sure what it is). Also as im not totaly certain about simply removing it how a regular exhaust could deal with a back fire(if ya ever had it)
