INSTALLED A DYNO JET KIT AND LOST 1/2 OF MY FUEL

the engine performs on what is going into the combustion cylinders and not what is going into the mufflers
you are hung up on the back pressure affecting combustion and air/fuel mixture
it will not air/fuel mixture but removing the baffles will affect back pressure ( which is very small in a motor bike to start with) but rest assured it will affect your wallet with excessive noise tickets from the local road authority
bike manufacturers engineer the exhaust systems for maximum performance and reliability from the engine and for any rider to believe that by removing baffles will improve that performance with out performing the resulting test on a dyno is just wasting money and kidding himself
noise is not performance , power or anything else
it is just noise

Buy a haynes or clymer manual soon

next time this happens grab your standard long skrew driver and open the carb. bown drains see if fuel comes out

If you have used Dyno jet kit I have had a kit come through with smaller main jets than the stock ones causing it to run way to lean.

Pull the slides from the throat of the carbs, Move the clip on the jet needles one notch lower, two notches at the most. Simple and didn't cost $400.
