It has been cold and wet so I have not started the bike for about two months. I know I kneed a battery tender but I haven't gotten around to it yet. I fired it up today no problem. My garage is dark and after about 5 to seven minutes of idle I noticed the pipes were glowing red near the heads. I have never noticed this before but I have not looked at it when it was that dark. Is it normal for the pipes to glow red hot like that? Other issues possibly? Everything seemed totally normal otherwise. Thanks for you comments or advice.
