RD400 first run after rebuild, very low power

[ElFuegoBlanco]

did you pull the jet tubes completely out and clean them and the air jet?

I think m in SC is the winner here. I did pull the tube from one carb when I rebuilt it. But obviously not the other. It was the grossest  carb part I think I've ever seen. I really don't know how in the 25 times I've disassembled it I never removed the tube to clean it.

I'm still going to replace the plug wires and caps tomorrow. And I'm inevitably going to have to split the case to replace the oil seal. The parts are on order, but until then, let's see what happens.

I pulled the motor to replace the leaking seal. Unfortunately, I forgot to order wrist pin clips. I realized today I have OEM clips, not Wiseco clips, and only 2 of them. So they'll be here next week. I wish I would have realized it last week.
It probably would be fine since there's only a total of about 5 miles on the motor since I installed the pistons, but why risk it.

I've been reading up on the correct way to tune the carbs, so hopefully I'll have better luck this time.
