    Question Bro 500 GT ABS won't rev past 6200 rpm

    2006 Scarabeo GT ABS. First long trip on expressway I had a chance to open it up a little, and voila', nothing more. I can cruise all day long up to 75-77 mph, approx 6k rpm, but it won't rev more... except... Once in a while if I hold the throttle open it will start taking off again pulling strong up to about 6500 rpm. Just weird since it accelerates great then stops, almost like a rev limiter. Just installed new spark plug, did the valve lash, and today fixed the old fuel filter gas line. No change. On my second tank of BG44k injection cleaner....

    That is a little slow. Are you getting normal mileage? Normal temps? Normal exhaust note?

    I don't really have a reference point for what's normal for exaust sound. Just bought it a month ago. Mileage seems ok, 55+ mpg. Replaced air cleaner also. On the freeway I can hold the throttle wide open and after about a mile or two it'll accelerate to 6500 rpms... If I let up a little it'll cut out again down to 6k. Acts like a rev limiter kicking in and out. Throttle linkage seems good, have full power range up to 6k. Bike has plenty of power. Next time I have the covers off I'm going to start checking all my connections... Specifically throttle position sensor... No dash lights on showing any problems either, although I don't know any additional way to check for fault codes
