Need mORE KZ650 HELP

Ok guys Need some new guidance.
Bike starts fine, runs fine after warming up and rides great.
But.... as you go through the gears and get to say around 55 60mph the bike will sputter a little bit and not gain anymore significant power.
So what are your thoughts?
You can see by my icon pic what ive done to the bike. the air pods have been added which fixed the idle problem. The air screws are turned out 1 turn. Wondering if the problem is Jet related, as in at higher speeds it isnt getting significant amounts of gas to support the load and speed.
Again i need some assistance
Thanx

If not already done, would assure proper functioning of the timing advancer, and also assure that valve clearances are within specs.

Good Fortune!

Might be a fuel restriction. Is there an in-line filter from the tank to the carbs? Might need to be replaced.

have you rejetted for the pods/pipe? more air coming and going needs more fuel to go with it

New inline filter already
Stock jets at this time
Has 4 into 1 with Vance Hines muffler.
What sizes of jets do I need to start with?
Cleaned carbs havnt checked valve lash yet.

I have attached a chart of sorts that describe some good jetting rules of thumb.

In your case as described go up 3 main jet sizes and one pilot jet size according to the chart.

Good luck man. Nice bike BTW

.

Allllright guys thanks for the comments and guidance.
Will look at the timing adjustment and points etc tomorrow.
Fuel Filter is new, clear and fuel is flowing thru nicely. Ordered from Z1.
Will order some new jets tonight and try a couple combinations.
Will report back when complete.
Need to get this bad boy done so i can start the 78 kz650 sitting in the shed.
