Noob question about power delivery.

[Sam13]

Hi. How long have you had the bike? Has it been sat for a while before you have ridden it? When we're the carbs last cleaned?

Basically I think you may have a flat spot in the mid range rather than all of a sudden more power.... well in a sense you do get more power all of a sudden. But due to the flat spot. If that makes sense :eek

I would suggest getting the carbs cleaned and valve clearances checked and go from there
