1986 trx350 gear reduction

hey guys, I'm sure this pops up on here all the time but I'm just starting to think about putting a gear reduction in my old 1986 trx350 4x4. This past summer i made a 2" lift for it and jumped up to 26" zilla's. It was a massive improvement and is great on the trails but gets bogged down in the skeg and thick mud. I haven't really researched it too much yet but I'm just looking for some knowledge if anyone has any :P I'm not even sure what all I'd need as far as clutch kits, clutch baskets, which gears to hunt down (probably looking for somewhere between a %15-%35 reduction) and whatever else I would need. I figured there's probably some guys on here that have done this before and could shed some light on what parts I should be trying to hunt down. Any info would be greatly appreciated, Thanks!

    Here check this link. Probably cheaper and easier than having to hunt everything down and machine it all to fit.

    Thanks, that was pretty much exactly what I was looking for. It says that that's a %14.5 primary drive reduction, in simple terms cause I'm a dummy what does that mean exactly, is it only a reduction on my first gear or does it give me lower gearing thoughout all my gears?

    I also read that you could run 28-29" tires with that kit. My little 26's should throw mud pretty **** good after this lol
