    Ya know, I clicked over on that one from the link you provided and just saw the yellow and thought---no. Completely overlooked the options.

    Good evening all,

    My son was given an 1982 IT 465 as parting gift from his boss. Awesome! It is is ok shape and runs well. It has been sitting in a seatrain for 12 years. We rolled it out, cleaned it up pulled the gas tank and carb and cleaned them out, checked the oil and kicked it 3 Times and it fired right up! Drive it around for a bit.

    My son has promptly disassembled it and is in the process of repainting, buying new seals and bearings, and other items. I am.pretty proud it's the first time he's ever done anything like this.

    Anyway, we want to upgrade the brakes, throttle and clutch cable if possible. We would.like.to put discs on it, and aside from using a newer model front end, is anyone aware of a aftermarket kit to swap the drums out? I imagine it requires a new front / Rear wheel, if so what would swap in pretty easy.

    Thanks

    There's no kit other than a fork swap. Properly tuned the dual leading show drum is a competent item. It'll never outbrake a disc but holds it's own. I used a Gunnar Gasser throttle and Motion Pro cable on my '80 YZ465. The OEM clutch cable is obsolete. Motion Pro makes a replacement.

    A shock service is a good idea. I run '82 YZ forks on my '80 with RaceTech cartridge emulators and springs. One of the best upgrades I've done.

    The 1980 YZ 465G had smaller forks that twisted easier, an electronic issue when on the rear brake hard, and slight porting changes.
    The 1981 465 H model had larger 43mm forks, a reworked ignition that didn't kill spark when the bike was "impending rear wheel skid", and cylinder porting changes that made more midrange and topend thrust.
    Because of the heavier forks (and more fork oil cap'y,) the weight went up 3 or 4 lbs from 1980MY.

    The difference between the YZ and the IT?

    The YZ is built strictly for competition. The electrics are not designed to power lamps, like the IT is.
    The IT weighs more, and has a larger fuel tank. the gearing is wider ratio'd for the IT.
    The engines differ by porting and comp ratio. The IT has more low-end and midrange at the expense of the topend rush of the YZ.
    The weight difference between the 2 models is about 25 lbs, give or take.

    I bought a used 1980 fork (38mm) from ebay and the top cap were in a very bad shape. I got them off but now I need to replace them. Original caps are expensive (45$ each off ebay) and I'm looking for a cheaper alternative. I found those on ebay for 39$ for the pair: https://www.ebay.ca/itm/FRONT-FORK-...XJ400-38MM-ADJUSTABLE-FORK-BOLT-/253202753735

    The manual state that the air pressure in the fork should be 0lbs, so I don't need the air valve, right? Do you think the one I found would work?

    Thanks

    Might want to research that OEM fork spring some. According to Race Tech the OEM fork spring was a .34 kg/mm spring and was designed to be run with 3-4 psi. I bought RT springs and they are designed to be run with 0 psi and are quite differant than OEM.
    just sayin'

    Bought this yesterday. It's a US import. Don't know what I'll do with it long term but at this early stage I'm happy to look it over and fix any niggles and go for the odd ride here and there when the mood takes me. Only just got it home so it's dark outside. Rear tyre's new but the front one looks almost as old as the bike.

    Thanks! It's not perfect (which means I can tinker with it :deal ) but it's pretty good and all the really costly bits are pretty much perfect. Here's a couple of daylight pics.

    Been a while since anything has been posted here. I figured i would see if there anything new in the thread. I was out in my garage, tinkering with my IT490 and WR200 and the weather here in PA is just about to riding season. I'll get some pictures of both bikes up here as soon as possible!

    Please do post some pictures of your IT490. We’re still working on our IT465 restoration. It’s a rolling chassis now. Needs electrical work, plastics, controls, and tires.
