    Cliff, I want a bit more speed, so am looking at down sizing the rear sprocket-was wondering if theres any other make or model that might substitute

    Oops, I misread your post. Most people want to gear down for larger tires, I didn't read your post thoroughly. Maybe someone else will chime in, but I am not sure what if any rear sprocket interchanges on a BW 200.

    Cliff knows that more teeth equals slower speed. He had the largest sprocket ever seen on a BW and topped off at about 20 mph. It dragged through the dirt when he made left turns.

    Yesterday just happened to be Opposite Day in Alaska, so Cliff was just offering backwards advice to comply with local traditions.

    I spent the day thanking Obama for the awesome job he's done on the economy.

    Regards,

    Mr. BigWheel

    What Mr. Bigwheel said:

    Fewer teeth = fewer teeth. Luckily he rides with a Dentist.

    My #1 350 came with a 47 tooth rear sprocket. I was not familiar with the bikes then and thought that it was stock. The sprocket was not dished and I was having problems with my chain staying on due to incorrect alignment. Also top speed was something like 30-35 mph, which at the time I thought was a design feature of the BW to compensate for the inadequate stock brakes on the bike.

    Mr. BW/Cliff
    I am doing the long travel conversion to my BW now.
    Using '85 Tri-Z forks and the YFZ600 rear shock with remote reservoir.

    My question:this shock is designed to run with the shock body on top but the top mount will not allow this because of the hose.
    I see from the pics that you guys are running with the body on the bottom and that is how mine is presently mounted.
    Does this affect the damping of the shock,running upside down?

    Spoiler alert! Mr. Bigwheel (aka traitor) is out riding snowmachines today! Shame on him! My loyalty to Bigwheels (and the fact that there is a blizzard outside), has kept me home stoking the BW fires.

    Shercoman,
    As you have discovered, there is not sufficient room to run the shock in the standard upright position, it must be mounted upside down. This seems not to have any adverse effect on dampening. Although I have been unable to mount the shock upright to compare. My stock BW shock seemed to have no dampening whatsoever, so the YZF shock in addition to increased ride height, will offer a degree of dampening which I found sufficient. You will enjoy the longer travel on both ends, and the disc brake will offer better stopping ability.



    Cliff.

    Cliff/Mr. BW

    Did you use the YZF spring or the BW spring on the shock?

    Do you know how many CCs of oil go in each fork leg for 1985 TriZ 250 forks?

    I know you guys are using '86 but thought you might know.
    Thanks.

    We are using the YZF spring. It may not be the ideal spring rate, but it isn't that bad either. We have talked about getting custom shock/springs made, but it has just been bench racing thus far.

    I am not sure how much oil the Tri-z forks hold. I do know that we used a cauldron of different weight oils not for performance, but because it's what was on hand at the time. I am running a '85 fork on my #1 bike, and an '86 on the #2 bike.

    Well call me a traitor but I am bailing out on the Big Wheels!

    Do not get me wrong, I do love em, but due to a knee replacement, lack of time AND places to ride I am selling out.

    Never really rode it much, always seemed to take a real dirt bike when I went out, so it has mostly been a shed queen.

    Am STILL having issues linking pics to this site so just put it on Craigslist.

    Did not know it was taboo to link CL ads....WHOOPS!

    How the heck did you do that?

    I have so many hours trying to get pictures to post on this site it is not funny....and now that I have a new camera I STILL cannot do it!

    I was going to show you pics of the 350 as well (it is just as pristine) but cannot get them here either.

    Lonestar 2112,

    I am selling it too, They are BOTH going away, just as soon as the new battery gets in and I wake her up from her ten year nap! She should be well rested and ready to go. I did wash off the dust and spider webs already.

    The 200 cranked over ALMOST three times before she woke up and I am certain the 350 will too.

    I am even thinking my '86 low mileage 1000 Ninja is going to be looking for a new home....whoever said you cannot have to many toys lied!

    Actually on that one, much as I love it I just cannot ride it very far since I got an aftermarket knee installed. Need something with a more upright seating position....like a Hypermotard! HA!

    Kubiak,

    Yeah it does and it would be even better if I had never wore my MX boots with those darn front metal toe tabs that scratched up the sides of the motor.....aw well, I said "almost" new, right?
