Reliability of Honda XR 250R

[kichaa46]

Hello people
I´m about to buy a Honda XR 250 R from the 90´s. I´m not sure about the RFVC system with the double rocker arm. Is it something that will brake soon or is it reliable? And how do you adjust the valves?
Furtheron I still hear comments from people about the engine, which some say is because of its power not reliable and needs early replacement. What do you think about that? I have graet experiences withe the XLR but I dont know about the XR.
Please give me some help.
Cheers.

I've never heard of any reliability issues with any Japanese machine, but usually the first thing to go is the valves ability to seal.

I believe that bike is a screw/locknut adjustment. Very simple, but can take a few tries to get the spec dead-on if you don't have the tool.

Just check the valve clearance (they tighten as they wear, & then they burn up & leak) & run good motorcycle oil ... & keep the oil clean. Should last you many many years!
