It was already known and therefore no surprise. The power valves didn’t look that good, 3 of the 4 sliders already had a slanted center pin, so these need to be replaced.
After some weeks I found some time and started to disassemble the whole bike.
Inspired by a post in a forum about a “noble bike”, I wanted to restore an Aprilia RS 250 to its original condition. I discovered the matching motorcycle in October 2008 on a site called “mobile.de”, with 20.000km and a price of 2300 € with complete original covering.
