while driving at around 5,000 rpm rex is bucking like crazy. Most notable on highway in 6th gear. I do not know where to begin looking. I have new plugs in it so do not think it is that. Any ideas would be great.

Check the small clear tube from the ram air to the carbs and check to see if the black plastic piece that it goes to is cracked.

this tube appears to be fine, but I do hear back firing coming from that side ever once in a while when down shifting. The tube seems very short. How do you replace this tube? Where do you get it from?

My rex is an 03 non fuel injected.

It's just a clear piece of hose home depot has it i'm sure... or even a pool supply store might be able to sell you something that small.

I just had one of my carb sync port covers crack and come
off. Thought I had bad gas, ran like sheet.

Take a visual of them between the carb and manifold, ya
just never know.
