WE went to a company called HOT CAMS they have a auto decompression exhaust cam and a nice intake cam. We just installed a set in our 426 it was simple. We replaced the timing chain with the cam swap. I am sure someone else is making these cams for the 426 but these are all we could find. We did not have to do any other mods other than resetting the valve lash. There is a very noticeable power gain throughout the rpm range.

I'm too far North (Dekalb) to help you with the install. You can get the cam for a really decent price through North County Yamaha. Give them a call don't order online. I got mine for 90$. Also order the blanking plug from the TT store, 24'ish$. All of the instruction and specifications you'll need can be found on TT. If you can find a Yammy shop that carries the shims it'll be an easy 1 day job.
