Carb is clean and starts and runs fine but after like 5-10 minutes of running it starts to bog and spit and back fire. Any Ideas?????

Check your kill switch and all your connections. If that doesn't you might have to run an oil cooler.

I'm running an 88cc kit on my son's 70. One thing we did was open up the oil line oriface in the case from 1mm to 2mm and install a larger oil pump.
We used the trailbikes kit. It's working great.
I would imagine the issue is temp related. That oil cooler might help I suppose, but I'm not running with one. I can't think of anything else.

My two friends have done the same kit, and they both say YOU NEED AN OIL COOLER.

Well, here's a long shot: Make sure your gas tank vent is open. Especially if you have replaced the hose with one of the little caps. It's been known to cause issues like yours.

check everything from your carb to how much oil is in the bike never run it low. I have a 108 stroker in my bike and it never done anything like those but i do have a oil cooler , high flow oil from Trailbikes, everything on my bike is Trailbikes and TwoBrothers racing , its pretty fast but i think i read to check the kill switch thats a good one to check to. Also check your head bolts to cause if loose to much air bike will get hot
