I have recently purchased a yzf426 2001, it runs fine when cold and performs well, as it gets hot it splutters with the choke off. It seems to run ok with the choke half on.
The previous owner:
• played around with the fuel mixture screw
• took the carb to a local dealer who cleaned it and passed it as fine
• changed the fuel and plug
Any suggestions?

Tight valves. Check your valve clearance.
