Ahh, friends... no need to be snippy.. I joined this site because I'm a proud Buell owner, proud Union tradesman that's supports a Finely , And only American made Super bike...Most my Harley friends disowned me for buying Buell.. All I'm asking of Anyone is their Personal experiences of What they're encountering. .. my case, cold or not..at about 5kish rpm, the tach needle lights up red... inquiries as to why ? No issues with the speedo nor sensor. ..yes, 10,500 rim redline. .. has Jardine rt-5 exhaust and EBR ECM. .( I INSTALLED ) the bike runs fine..****s n Gits.. just curious to tach light-up because that's where there isn't power band or significant notice to do something. ..This site has been so helpful , so far... I appreciate everyone's input. ..thanks.
