yesterday my new-to-me 350 hours of use BX2370 just blew its core out of the valve stem, or it broke off? anyway a pliable rubber valve stem with steady stream of liquid pissing out of the valve stem on left rear tire.
my first thought: fine, I just poked a sidewall hole with sticks.. then saw it was all coming from the valve stem..or what remained of a valve stem. rolled forward to put the stem at 12 o'clock, and there it sits.
I had already decided to buy R4's to replace the turf guard tires to avoid sidewall punctures, and went for the wheels and tires installed route.
now need decide on fluid, foam, or whatever for wheel weighting.
