I would like to know if anyone is familiar with how often the top end needs rebuilt on the Honda TRX 450r.
I was told from a Honda Service Manager that you need to rebuild the top end after 20hrs of use and so on. I guess once the 3 piston rings wear, the piston becomes sloppy inside the bore and gulds the cylinder walls.
When performing a rebuild, if the piston is in good shape, can you just replace the rings? Or, do you need to replace the piston with the rings as a set?
Any additional information will help, thanks.
