Welcome aboard.
Pro tip: punctuation helps. More people will help if they can more easily understand what you're saying. Kats are old bikes, most of us are older too.

I think you said that when the engine warms up, it bogs down at low rpms, but at higher rpms it's ok?
That likely means you're running rich, could be a couple reasons for that.

Could a aftermarket exhaust do it




When engine is warm and I take off it boggs like not getting any fuel I have to hold accelerater halfway down to get it to go. Like a sputtering then it will finally go it idles just fine but when I take off it will bogg

Probably have fuel in the oil. I'd check for that first.

Anyone out there

Aftermarket exhaust: no.
That would make you lean, not rich.

What you just described with the throttle, that's definitely pointing to it being rich.

Yes it has an oil filter, up front under the headers.

To check for fuel in the oil, take off the oil filler cap and sniff. Smell like gas? Problem with a couple different possible causes.
Doesn't smell like gas? Cool, that helps narrow down other possible causes that would make it run rich.

Ah, hell.... do I have to say it?? How does it idle? If you throttle up while going does the Roma climb but, the speed lags? Fuel filter is visible on the left side near the petcock. Check your sync caps and vac hose(s) for cracks. If all checks out you may have to clean those carbs.

It idles fine I noticed the friction zone non clutch is all the way at the end it don't grab til its like fully released could that do it

Absolutely. The highest drag is on start off from a dead start. Time for a clutch adjustment at the least. http://katriders.com/vb/showthread.php?t=64698

Clutch slippage does replicate a second gear take off.

OK my fuel filter is just bouncing around in case is it suppose to do that
