depends,if your both 90lb midgets then you will be fine!
most ppl are to big for stock rear spring on a stock bike let alone a stretch one,I stretched mine +6,at 290lbs I couldnt even sit on it without it rubbing,I sent an 08' shock to traxxion dynamics and they hooked it up for $240...they will make it for your weight,riding style and compensate for whatever stretch you have,mine had a 1" spacer with a 1300lb spring...PERFECT!!
