hi guys im back, this time with a xvs650. got a good deal on a 2008 custom (6,500) from a 50ish lady that had kept her pretty tidy. my question is..... at around 60/70 kmh 4th gear sounds like its starting to rev to high but when i pop into 5th she has this "sound" that sounds like the drive sharft is overloaded for the speed its doing. its like this from about 70-90kmh. it go's away the higher the speed (may just be that i cant hear it). it makes me think that im changeing to early but as i said 4th seems to rev to much (no tacho). i dont think its a major issue but i dont want to fcuk my drive shaft ? any sugestions ?????
