So i just picked up a 99 cr125 from a buddy for $100. The reason it was $100 is that it is completely torn apart, all the way down to the frame stripped (i have everything). Here is where my reason for posting comes about, the motor needs going through and a few parts replacing, thinking about doing the 144 kit as i have read on this site (im very new to this site) but do not really know where to find parts to do the kit. I do not have a carb, what should i do as i have read the stock carbs are not much to be desired, so i cannot see myself spending money on something thats not worth it. Lastly, i have read multiple posts about upgrading the suspension, can you guys give me ideas on what should be done. I figured i would post this before i start rebuilding my bike so i know what to put on before i waste money on rebuilding junk stock parts. Thanks
