I'm having an issue with a BRAND new skyhawk engine. These things are full of problems...

Occasionaly, when I start the bike, it goes into this state where the combustion noise sounds a bit different (that put put out noise the cdi makes when sending the spark) and then I can't go any faster than 30. It's not the choke, carb is jetted properly, and as I said, it doesn't always happen. I tried to eliminate and find as many variables possible but with no luck. Any ideas?

if i had to guess, you're 4-stroking or you're not getting enough fuel to the engine. Check to see if you have good fuel flow, and if you are still having issues, you can learn about 4 stroking from plenty of articles on this forum...
