    I've been called a pig on a 350 before, but I don't believe that they are pigs on gas. Of course, they are not going to get as good m.p.g. as the thrifty 200 but manly, fire-breathing horsepower always comes at a price. On most rides, I spill more gas when the bike is upside down in rock piles than I burn in the engine.

    The early TW shared the same forks and brakes as the BW200. I imagine the BWs would have gotten a disc front brake along with the TW had the line not been terminated.

    The rear shock is also interchangeable between the TW200 and the 350, although the parts numbers don't match.

    All three of the bikes utilize the same Female Repulsor. The 80s did not come equipped with a repulsor and as a result are often considered "cute."

    Regards,

    I tend to think the tw is a better design then the bw 200 because it usues a swingarm and not the jackshaft.THe jackshaft is not only heavy an power robbing,when I hd the sprockets and chains replaced the mechanic said even w the new hardware the chains seem to still have to much slack and the adjustability just isnt there. I was watching the videos of the alaskan outback.:eek1Holy crap the iditarod trail looks more like the I didnt ride trail because I crashed my brains out and got the bike stuck every 5 feet:lol3.I know the 350 is more manly then my lil 2 hunny moutain goat nanny but they are just so hard to fnd over the 2 hunny.

    A BW without the whole horrible jackshaft arrangement is just a FatCat. The awesome thing about the BW is that big, fat and wide rear tire. The FatCat just can't fit a really wide tire on it's swingarm because it doesn't have the jackshaft arrangement. It is both a blessing and a curse.

    The best solution that I have seen is Shercoman's TT500 build where the jackshaft is mounted eccentrically as opposed to our eccentrically mounted swingarm. That still causes me daydreams about KTMs with fat tires.....mmmmmmmm.

    When I click on that link, it takes me to a generic Australian Yamaha site. Could you try that one again jaubuchon?

    So, has anyone plated the 350? Mine has a full Washington title, and when I do the switch I just have to ask for plates correct?

    I have a Wa, state title and license plate for a 85 -200 and it has been plated for 27 years , when i bought it the gal at licensing just transferred it because it was plated before..dont think you can get one plated that had not been in the past...i am going to add turn signal's with L.E.D. flush mounts and a horn to be more compliant. I just know some patrolman is going to have a fit that the tires are not rated though...just a matter of time before that confrontation with the man..i figure its grandfathered in at this point as im not using it on highways ......

    Washington is a PAIN to deal with plates... If your title or the bike says on it anywhere "off road use only", your toast. If you have a current plate, run it until they tell you you cant! Getting a plate- good luck. Idaho, on the other hand, lets you plate just about anything depending on intended use. You can get plates for straight up dirtbikes- but you can't take them on all of the highways.

    New guy here - just bought a 1986 BW200 with about 40 hours on it. Need to redo the primary chain, then it'll be ready to go. Great thread with lots of good info!

    PS - also have a Rokon Trailbreaker. I'll compare the 2 bikes once the 200 is going.

    Welcome aboard Duster11. We await the results of your showdown. Of course, we are all rooting for the BW over the Rokon.

    And thanks to yokoboko for the link to the owners manuals.

    I recently returned from a three week trip to find out that some jerk had left the BigWheel filthy and covered in mud. So, to make reparations to her, I decided to make a minor upgrade.

    Presenting: My Latest Hack Job (literally)

    The problem:

    [​IMG]

    As discussed previously, mud builds up under the left side engine case cover. It is hard to see and impossible to remove without removing the cover.

    [​IMG]

    On your average dirt bike the countershaft sprocket is left largely exposed and is easy to get to with a pressure washer.

    [​IMG]

    Since the BW is anything other than "average", the countershaft sprocket is almost completely enclosed and impervious to the ravages of a pressure washer.

    The Solution:

    [​IMG]

    Three jigsaw blades, two band-aids, a new gasket, 12 hand-rubbed coats of lacquer and new hardware (to replace those wonderful phillips-head fasteners made by the Tokyo Margarine Factory in the 80's) and the project is complete.

    The New Problem:

    Now the rest of the bike looks like hell.

    It's been below zero fahrenheit for several weeks. Now it has warmed up and dropped a foot of snow on us. How am I going to find some mud so I can get that part to blend in with the rest of the bike?

    Regards,

    Mr. BigWheel

    Anybody happen to have a bw200 parts bike? I could use a few things, mainly an airbox for an electric start model (with battery holder). The previous owner of mine ripped it out and installed a cone filter directly onto the carb... Not going to work for a dirtbike!!

    Ah the joys of resurrecting 25 year old dirtbikes... :freaky
