hi, my friend has an 03 125sx that he doesnt want so hes selling it, i kinda want to buy it but theres possibly a problem, it wont reach peak rpms/doesnt hit powerband(thas why he doesnt want it), is that bad (i know that means it isnt working proporly what i meant was how bad) basically what i want to know is... 1.how bad is this for track and trails (will i stall, get stuck easier, have trouble with sand/mud, and or struggle with hill climbs) 2.is it just consistant power flow like a 4 stroke or will it be harder to start, take off, or go fast? 3.is it possible to/how much would it cost to fix this? 4.will it be bad for trails with larger rocks and small logs (i dont normally ride 2 strokes and when i do i go though gears so i honestly dont know the difference between having it and not) 5.basically, is it as rideable? will it work fine as long as i go though gears? 6.do you think i should buy it? he already put 700 into it and ive seen the receits for all the work he did to it too, hes been riding it on trails abit too, hes been riding two strokes forever though and loves powerband thus hes getting rid of it 7.i ride track sometimes, will it be ok for jumps?
