While scouring the tinterwebs looking for what kind of bulb Bee's sidelight is, I stumbled upon this hidden beauty. Explains (with pictures) how to do valve clearances on the YBR, as well as Oil Change and Exhaust Maintenance. I found it highly informative, hopefully you other YBR owners can too. http://www.bikechatf...99902da#3152113 EDIT: Rear wheel removal, drum brake service + Air Filter Replacement http://www.bikechatforums.com/viewtopic.php?p=3152965&sid=50cda70908b7da8aa75658e1399902da#3152965
Would this apply for R125? I know they're pretty much the same engine but not sure if there are major differences that would make this guide not suitable.
The very basics, I'd imagine are sort of the same. But the R125 is only based on the YBR engine, so there are lots of differences. I'd say find a proper manual specifically for the R125, as the valve clearances may be different.
