I have a 2005 yz125 and im thinking about a 144 or a 134 bore, but i dont know how reliable the 144 is. I want somthing that will give me the edge but i dont want to change rings and pistons to often
hi mikeMikeeeP said:KTM125 with Eric's 144cc kit - I ran it forever - I kept taking the cylinder off checking the piston and it never wore out. I put fresh rings on it and the darn thing lasted for over a year on the first piston. I finally just changed it to a new one because I was tired of pulling the jug off every couple months to check it out - actually on the 2nd piston, I started pulling the exhaust pipe and peeking up into the exhaust port to see if there was any blow by on the rings... never was. I sold it before it ever needed a 2nd piston, and I rode it for a year on/off that time as well.
So I dunno - Eric might just be being safe saying to change them so often, but they lasted longer than any 125cc bike I ever owned!
