It sounds to me like your jetting is just off. You 78-82 isn't that large of a range to try. You said you can ride it occasionally; what's the plug look like? The plug will tell you what you need to do to the jetting. Look up Plug Chop on the wiki if you're not familiar. You don't have to hacksaw off the threads or anything, just get a good reading on the plug
