Hello everyone, first time posting. I just bought a 2005 st1300 with about 16,500 miles. The bike runs very well, but being the third owner I thought I'd replace the air filter and plugs along with fixing the heated grips and 12v outlet. My question is, should I also change the coolant. I checked and it looks green and clean and the bike has no visible coolant leaks. If so, what coolant should I use without silicate and borate (s), I think that's right.
