Hi there guys on my 2007 Busa. When I hammer it, it feels like a power band is kicking in. this is not what bothers me: it is the fact that it is very inconsistent . at first it only happened in first gear but does experience it in second gear as well. I did recently service the motor( plugs, oil , oil filters, air filter) also did change my chain and sprockets today. But still got that inconsistent kick. Please give me some advice what to look out for.
