yeah the secondary is the main cause of upshifting and backshifting problems usually. the secondary clutch is designed to funnel air into itself as it spins in order to keep itself cool, when you get water and mud in the belt housing the clutch spins and funnels the mud and water inside itself, and will cause adverse effects on how the bike shifts and reduce the belt pinch. the secondary spring is the belt tensioner, it has a spring inside itself that squeezes the secondary shut to keep the belt tight, when you get mud gummed up inside the secondary, it will not allow the clutch to close up properly as it should, as well as reduce the backshifting characteristics of the bike. after swamping a bike you should take the clutches apart as soon as possible, and clean them with brake cleaner in order to push water out of the felt bushings that are in the movable sheave. when those felt bushings get wet, they swell up and will sieze the moving parts to each other which will seriously effect the bike in a negative way.
most likely you need to take everything apart, and give it a good cleaning. i can machine the clutches and manipulate them in a manner that will give you more low end, as well as more speed if you wish to do the extra steps. you can get the bike back to factory operating ability with a good thourough cleaning of the clutches in order to make sure everything is clean but it will require you to build a tool in order to compress the secondary so that you can pull the secondary clutch apart. on my website (in my signature) there is a page that shows the disassembly of the clutches. it will give you the necessary information on how to pull the clutches off the bike. if you need some help my website also has my email address on it you can directly ask me questions and i will help you in any way i can
