I don’t know why everyone says it’s so difficult to remove carbs with an airbox. You can pull the airbox boots into the airbox by sticking your arm in it, and it can be done with hardened ones, too. I’ve done it many times myself. But on the topic of pod filters, I just bought a set of K&N for the cv carbs that I bought for my ‘81 KZ650 CSR because an idiot destroyed my VM’s by leaving them in solvent way too long. I bought and installed a MAC 4 into 1 and will be installing Dynatek Dyna S ignition with coils, and have ordered 137.5 main jets and 40 pilot jets along with needle shims. Let the fun begin.
