2 Gen acceleration problems

[Erick Green]

I have a 2008 Gen2 Busa. My bike studders when accelerating hard In the upper rpm levels. I’ve replaced the fuel pump, spark plugs and fuel filter. Does anyone have any other suggestion? I forgot to mention the bike is stock except for slip ones.

Something cheap to try: put some sea foam in the tank and run through a tank with it in there and see if it clears up. Also make sure you take the bike above 7k rpm while doing so, that kicks in the secondary injectors which may be clogged if they haven’t been visited frequently and the bike has sat for some time.

Start with the basics check air filter and air ducts for trash debris etc

Secondary injectors clogged. Very typical on 2nd gens.

Coils? I had same problem with my kawi and it ended up being one of my coils.
