    THe only bad things on mine are no outter chain guard,the shocks are undersprung and the lighting coil went out.When I get or if I get more money Id like to swap out the cdi/lighting coil,get the guard and put werks shocks on it see if that helps any.

    Cliff,

    I did indeed put the wheel on the axle with the seized bearings. But that is only because both of the spare axles have seized bearings. I'm lucky that they are not seized on the running BW after all of the maintenance that we did after the last ride.

    Speaking of Cliff, this is a picture of Cliff's Crash Site:

    Of course this shot was taken in daylight hours when it is obvious that you shouldn't ride through this at speed.

    There we were, minding our own business, when out of the darkness a great void in the ice reached up to grab Cliff. He can now only walk in 10 foot circles and belongs to the Ministry of Funny Walks.

    The object lessons:

    1.) If you have any possibility that you are going to ride after dark, ensure that your headlight is not
    aimed at the tops of the trees.

    2.) Do not watch a captivating sunset from the top of a mountain and then say "uh oh."

    3.) Helmet lights are a great investment. But obviously not one that we have done anything about since discussing it in this thread roughly 12 months ago.

    Regards,

    Mr. BigWheel

    To those unfamiliar with the above trail, there is a crashed B-29 bomber near the top of the mountain in the background (not visible in pic). I crashed the Bigwheel-350 at a much lower altitude. I can almost walk again without the aid of crutches. But alas I will soon throw a leg (but hopefully not break it) over the BW again in the winter months to come.

    If anyone else wants to use this wheel and go to a 10 inch tire I can modify more of these wheels easily.

    sanjoh,

    Those lights do look pretty sweet. Is there any realistic possibility of making a helmet light out of the 3600 lumen one? Or is it too heavy, bulky, etc?

    Love this thread... Not sure if I posted here before, but if not, I have a good excuse.

    Look what followed me home today... BW200 with electric start. Of course it doesn't run, and is ratty as all hell. But, I paid next to nothing for it. It will be my third big wheel, I have two BW80's.

    I was celebrating my victory, rolling it down my ramps out of the truck...... When the front brake seized up. The cable is so old that it won't move.

    This is going to be fun!

    That's in pretty good shape and it looks like all the parts are there.You're starting out much farther along than many on this thread!
    Doesn't look like many miles either.That back tire looks pretty fresh if it's original.
    You'll have a hoot with it!

    Has any one pulled the cork out of the exhaust?I tried to get the insert out and it must of welded itself to the outter steel can.I guess 26 years and lots of heat cycles will do that?Any one ever put performance suspension on these bikes?

    Thanks! The pic shows the good side. From my initial casual inspection, I am missing the left side cover, and the airbox. The previous owner rigged up a cone filter directly on the carb, and there is no battery, so I have not been able to try the electric start. Hopefully the wiring is intact!

    Also... Somebody rigged up a thumb throttle on this thing! That's a first on a dirtbike for me lol... I'll be converting it back to stock.

    They weigh 8ozs which is a bit heavy. We do have a helmet mounted light that is 4oz.

    How about a headlight replacement that fits in the stock fairing? A couple of 60s should fit. I can setup a low beam to conserve retinas.

    It would not be DOT legal but I've been running the same setup for many thousands of miles without issue on other bikes.

    Mr. BW and Cliff H
    Please refresh my memory on the rear shocks you are using.
    I have some longer travel forks but need a longer shock to balance it out.

    How much additional travel did you gain? Maybe you could give me a measurement,say from the axle centerline to the bottom of the fender-unloaded.


    Thanks!

    Hello there big wheel people, I have a historical trivia question for you. The first bike I ever rode had fat tires and small rims, but it was a full-sized bike, not a lawn-mower mini-bike. The outer wheel size was similar to a normal trail bike. The bike belonged to my friend Shane's family, and they referred to it as a "Chibby" (my phonetic spelling). It was blue, and had enough power to wheely Shane and I off the back when we were 10 or so & riding two up. The vintage was probably early 1970s. Fender, tank & side covers were metal, not plastic, and the seat was a conventional flat two-person 'loaf of bread' like a 60's or 70's street bike.

    In recent years I've tried to figure out what that bike was, and have gotten nowhere. I figure here on this thread, there might be some people with a knowledge of other fat-tired bikes beyond the Yamahas . . . does my limited description ring any bells?

    (feel free to PM me if you are stumbling across this post some time long after it was written)

    I (we) are using a rear shock from a Yamaha YZF 600 (I think). Mr. Bigwheel was kind enough to provide me with a shock from one of his previous attempts at rear shock upgrade. The measurement from the centerline of the rear axle to the rear fender (measured from the axle to where the end of the seat meets the fender) is 23.5". I am not sure what the stock measurement is, but a couple of inches of travel is gained, plus I now have rear dampning where the stock (25+ year old) shock seemed to provide no rebound damping whatsoever. I ran this setup on the rear for most of the summer without an upgrade to the front suspension. With the rear suspension jacked up and the front not modified the steering angle was rather steep and caused some rather twitchy steering. I now have a tri-z front suspension on the BW and now have a steering angle which is much more relaxed and easier to handle (in addition to a front disk brake!). The only disadvantage from what I can tell is that the primary chain has to be run a bit looser than what many may be comfortable with in order to cope with the geometry of the longer suspension travel.

    Cliff.

    Singletrack_mind,

    How about a Rockford or Bridgestone Chibi (means "short")

    Shercoman,

    Cliff usually lands on his head, but he hit it on the head this time instead. It's a YZF600 shock mounted inverted. Some years had no reservoir, some had a remote reservoir and many years had a reservoir on the shock body. I don't think that we have enough clearance between the tire and the shock for the latter. The ones with the remote reservoir allows independent adjustment for rebound and compression damping but the one without the reservoir works just about as well.

    Both will still leave you wishing for a little more damping anytime the wheels leave the ground.

    If you need any more measurements, I'll be back home tomorrow and can get them for you.

    Regards,

    Mr. BigWheel
