Hi Guys,
So after a few hours of riding I thought I would check my valves lash and was I surprised to find out that there was more lash when hot....after it cooled down after 3 hours I checked it again and it was tighter when cold.
Thoughts ?
Dont undestand why as it had no problems running with the standard rocker and changing to a roller type, its still runs off the same profile and lift but just a roller on the cam.
Ok so done a mild port and polish on the gpx 125 and also had to drop the main jetting and up the pilot and wow what a difference ....! Also looked at the rocker and it a j type so can i just put a j type roller in that i got from ebay.?
