Recently purchased bike. Been stood for a year or so. Starts and ticks over fine when cold but when warmed up becomes a complete pig refusing to tickover when warm. Runs fine off tickover so is this electrical or carb? Removed and cleaned carb (no issues) but still the same... Battery is goosed, but will this affect running?

Did you blow both jets through ????
New plug ???
Fuzz....
Always a smaller backup bike to hand !!!!

Some XBRs were reluctant to tickover and Honda issued a new jet kit and revised tappet clearances. From memory the inlet went up to 15 and the exhaust up to 19 (no idea where the decimal point goes in front of those figures, I'm a bit clueless about such details).
Main jet went up to 158, can't remember the pilot jet details.
Having said that my last XBR had the original 152 main jet fitted and ticked over great.

There's an idle mixture screw beneath the carb on the side away from the engine. There's no room for an ordinary screwdriver but you can use a small flat bit with a pice of rubber tubing jammed onto it. Do no more than 1/4 turn at a time. Out is the usual fixer.
