I have a 06 sikk mx xl perimeter 125cc. I have been very impressed with this bike all around. It has taken everything I have thrown at it with no major problems. I recently was on ebay and found a 141cc kit for my 125. I was wondering if any of you guys have used this kit or heard anything about it. The 125 has plenty of power, but why not upgrade to a 141 for more power.
