Hey I recently bought 2005, 50tkm F650GS with BMW system panniers, seat and handle heaters, ABS. Now I have noticed couple of things which bothers me a lot. - I think it's lowered. I am 180cm/5'92 and it feels way too small. I don't know how to check it but I get that feeling that front is way higher. Is there a way to check it without dismantling the bike? I have tried to adjust the suspension knob and screw but no difference. (edit: It is lowered, 5 coils in rear spring and seat product code is for lowered) - It sounds like sewing machine! to be honest, it does not sound like motorcycle. I don't mean that it should be like harley with shotgun pipes but come on... It seems that there is quite narrow offering on aftermarket exhausts for this bike anymore. Not to mention, how do I find one which fits with the BMW System panniers? - Also it feels little powerless. I know it's thumper and with odd 50bhp but combined with poor sound, It feels like I am taking to limits. It feels like it will break soon if I give it a throttle. Also when giving some push/torque, I hear the vacuum/piston sound "ploploploploplo!" (can't really describe it). - The front brake squeal and pulsates now and then. Not always. First I was afraid of the infamous steering bearing fail but I lifted the bike to center stand and with front wheel in air, I moved the handlebars end-to-end and did not feel any "bumps". My guess its the rotor which I measured to 4,5mm thickness (I think 4mm is the limit?). Am I being retarded or what should I do? To make things worse, I bought Aprilia Pegaso 650 (97) which is with same rotax motor but that sounds like V-twin and moves nicely with original exhaust and twin carbs. It's so weird how big the difference is around the same engine!
