Has this always happened since you have owned the bike or has it just started happening? 2.Have you made any changes recently to any part of the bike? 3. What is your maintenance schedual like? How long since the bike has been pulled down?
I could take an absolute stab and guess it is a carb issue possibly a blocked jet, or a power valve issue or an electrical issue but we realy need some more info.

Thanks and to answer your questions:

1) It's always done this but then I've only had the bike since December and have put maybe 200 miles on it.

2) The bike is completely stock with the exception of no air filter. The old one was completely dried out and was sucked through the carbs (possible cause or related?). New filter en route from Tyga.

3) As far as I know the bike has never had any kind of major work done, it's only got 11K km on it. Compression is 130 in both cylinders. Only mx I've done so far is to the brakes and chain.

Thank you for the help!
