You computer (CDI) may be bad. The CDI box could have moisture in it. Although, this box is a sealed unit. After time the box may develop hair line cracks in the seams where it joins together.

If you can rule out bad gas. I would try the CDI. Amazon may have one for your ride. I just bought one from Amazon for a Yamaha Rhino, fixed my back fire issue.

Have you checked your valves? Timing? Adjusted the air/fuel mixture?

I’d check the basics before I started throwing parts at it..

No sure haven't

I would go through and check/adjust everything.. probably not the CDI if it’s firing.. But, you never know..

Shoot some starter fluid in the intake, crank it. If it fires and runs you have carb issues. If it still backfires you have a bad CDI or it might have jumped time.

I've tinkered on one of those. Carb overflow wouldn't seal up. Was a PITA.

Good tough little bikes though

Those bikes are tough. A buddy of mine has one and that thing is like a tank. Always runs good too.

If you put a hire octane fuel would that burn the valve up faster

I concur.
The only bayou's I've worked around had problems w/ timing chain and would get out of time(get bad enough to jump time) can't remember if it was chain stretch or tensioner problems as the models I am thinking would have been from the mid 90's so it has been some time ago.
but as stated earlier check timing...
