I have been wondering this for a while and did a quick interwebs search and found nothing.
When it comes time to overhaul my 99 honda 125 motor what do people do to to the jug? I know on my kx125 I would send it out to be re plated and it was good to go. Everyone looked down on having one sleeved but it could be done.
What is the norm for these honda motors?
I would like to think that I will be into the motor before any serious wear ever happens but you just never know what your dealing with until its apart on the work bench!
First off, there’s no reason to replate a cylinder unless there’s a score in it, or it’s out of spec, which is unlikely. The reason they don’t allow replating in the stock Honda class, is that part of the replating process is to clean up the slag left behind from the plating operation. The “clean up” would be hard to regulate, and in the right hands, could be a big advantage… And as stated above, you can get a new cylinder for about the price of a replate, so would you anyway?
Run a fine flex hone through it, wash with soap and water real good, put a fresh top end in, good to do….
Chris–I use a soft brush hone to put a nice cross hatch on the cylinder wall when I rebuild a top end…have you ever seen one of these? They’re really nice and do a great job….I got one on ebay for about $50, and Wiseco markets one that costs about $80. Here’s a link:
