Modified needle bearing made to fit bushed wrist pin hole
I bought a cheap motor online that used a wrist pin bushing but after a summer of riding the bushing began to go and needed to be replaced but i could not find anywhere that sold them. somewhere along the line i purchased a spare piston set online that came with a wrist pin needle bearing and i found that if you remove 3 of the needles evenly spaced that it will fit and work quite nicely in the wrist pin designed to fit the bushing. I have been running my bike for about 6 months now with this modified needle bearing and it is still going strong.
