    YZ490'S are autolube...unless the system has been disabled...just like Honda DT's...duh.

    You idiot, the DT is a Kawasaki, and Kawasaki have Posi-force lubrication not autolube...

    But if you want to see a thread that will give you callouses on your forehead from constantly slapping it, I stumbled on this old TT thread a while ago while looking something up (remember it is an old thread so I wouldn't reply to it) http://www.thumpertalk.com/topic/593638-twofour-stroke/

    New chain and sprockets. 14/52 should be a real tractor. :bmwrider But really not that crazy, when you consider that some WR500 came stock with 14/50 and a lower first gear. I need a better tire for the mud. What would be a good tire for a YZ490 woods bike? It gets pretty slick here. And we have a lot of clay that really gums a tire up. I can't wait for more rain! :amazon

    What year YZ490 are you looking for? I have to stop looking. I'm going to keep my YZ465 and 82YZ490, but once they are sorted out. I'll be looking for a newer 5 speed yz490 and maybe a IT465, to add.

    this has turned into an interesting thread :D

    I've been searching on and off for several years for a nice IT490, which I'm sure would be a much better starting point than the YZ490 for a woods bike - but I've no doubt the YZ can be made to work well too.
    I like the idea of the IT's lighting coil, as it's still easy here to plate a 2T dirtbike if you have a head/taillight.

    I had a bead on a beauty in central CA a couple of years ago, but at the same time saw a 380 EXC closer for the same money....and went that way.
    Still wished I'd gone with the IT490 - but hindsight is 20-20.

    Whenever a decent WR500 comes up, I have to go take a look.

    There is still good riding in the area, its looking like a tough go for the enduros that are held in the area. All the clubs that use the area for their events are having a tough time with the greenies and such. I can ride from my house and hit quite a bit of good tight stuff still.

    Being from Utah I'm probably the last guy that should give advice about good mud tires lol. Anyway I really like the IRC M5B in a 130. Killer traction, good wear (especially for a softy) and strong carcass. I like them in anything from singletrack to desert.

    If you are a superstar ex works rider and holder of 14 world land speed records, then I guess its certainly possible to ride a dreadful old open class MX bike fast in the woods.

    Most are less able though, and would find a smaller bike much much easier to ride, and would be able to go faster than on the open classer.

    For playbike use autolube oil is just fine.

    Posters on this forum seem to have achieved all sorts of things, but up to now not a single one of them has posted anything whatsoever to support any of their claims.

    I can just as easily claim to hold 10 world land speed records, have won several Moto Gp races, and anything else that sounds impressive. Bit more difficult to support those claims away from the keyboard though......................lol

    I'm guessing that you are not much older than 10 years twin-pooper.

    OK, we are way of track here.

    Can we drop all the crap that isn't related to the IT/YZ490 or I'll go running to the mods again.:D

    Thanks.

    The older KTM big 2 strokes are nice woods tractors,I rode a 1979 420MC for 4 years,rode shorttrack,MX,Marathon MX/Scrambles but mainly trailrode it,nice smooth engine right out of the box and at the time very reliable.

    Then I had the 495 which seemed to be a little more then a person needed in the woods,I tamed it down a little but could usually go faster on the 420.
    The drum brakes were not awe inspiring

    Ive just brought home a 1982 single shocker 495,complete but been sitting a while. The Euro bikes had the forged pistons back then and tended to run a long time between top end jobs.
    Harder to find a decent one now.

    (funny people do tend to check in on this thread)

    Shane was at the very top of his game back then,he was a loon then and is still,there were pics of him 6' off the ground where others were on the ground hitting bumps and ruts,he had some good years.
    A decent 200 is 36hp,a light guy with the throttle pinned can fly on one.

    Thanks. I have a IRC VE-33 510x18, on the YZ465. It's only has 70 percent left, but still gets good traction. I'll look at the M5B too.

    Some riders from the UK recently set several "world land speed records" at Bonneville using BSA Bantams..............kind of puts it into perspective dont you think?
