    1981 Atc 250r Mugen Build

    Picked up this tricked out 81 from another member. If you remember, he had this posted for sale a few weeks back. After looking at the pictures, I had to have it so off to Indiana I went. There is more history on this bike than I will likely know, but I have spoken to a few members and here's some of the potential goodies to date. I say potential because some of these items are still an educated guess.

    3 tanks came with the purchase.

    1. Is an OEM peanut tank with a cover
    2. Could be a Malcolm Smith 250R tank
    3. A fiberglass Tank. Could be a Fibertech out of southern california

    3 Pipes came with the purchase. Currently on the 250R is a Bassani

    3. Is an old school DG

    Here we have a CalFab swing arm re branded as a DG SuperTrack and a Works Shock with MaxxTraxx + 5 axle

    Currently, it doesn't run. I will be pulling the cylinder and head with a one way ticket to Selvy. I will also be mating up the 41.5 taper bore mikuni and will be repacking and running the 1 piece DG. There are a couple more odds/ends that I am going to shore up before I go and have some fun and I will be documenting it here.

    More fun ahead...stay tuned.

    Awsome glad you got it. The first pipe looks like my old school DG.I think the second pipe is Phase 5.This is a realy sweet R. I remember when Jesse built it. The front forks are 83-84 250r.

    That thing is so cool. Seeing it makes me sad I passed on the "Dirt Works" first gen Captain Weezy sold a few years back. My prediction is with Tecates and 3rd Gen R's becoming too expensive for the average guy, the 1st and 2nd Gen R's will start gaining value as the introductory hi-po 2 stroke trikes.

    It also has one of the first Flotec modded 330 liquid R piston conversions.He milled the head surface and matched the ports.I agree about the 81-84 R becoming the next sought after trike. Glad I have my 81,83 and 85 plus some extra stuff.My 81 has a triple rate Works. Any plans on racing it. couple guys on AF had the one piece DG they sound awesome.

    You hear of someone building it? You must be hearing echoes in your shop

    Great pickup! Lots of goodies on there. Mario made those number plates a few years back. I messaged him this week hoping he still has one left somewhere. That case saver is slick. Better polish up that bad boy and bolt it onto the Cammex motor lol.

    LOL, ya know, Paul said I would be an air- hero if I ran a set of those. I may consider doing it for anyone who wants one.

    Glad to see you got it Brendon . I offered to buy it Friday night,but he said a guy was coming down around Thanksgiving and he was not taking my money till you looked at it. I told him you were a good guy and wouldn't steer him wrong. That is one very cool grab right there.
    Please help those who cannot help themselves.

    ALWAYS buying Museum quality machines,3 and 4 wheels. And any and ALL ,NOS parts,EVERY brand.
