    Thanks! It kinda was a smack in the face barn find. I wish I would've taken it out earlier, but when I was little I was scared of it...And I thought it looked stupid. Oh gosh how wrong I was. I'm just hoping I don't break it more by trying to fix it.

    Hi guys,

    I just picked up a 1985 BW200. Bikes complete and runs ok. I plan on a full resto-mod build up. Only bad part is the tank has a few holes in it. Anyone ever swap a larger ATC tank on one?

    I'm 90% sure I'll end up swapping in a larger motor. Maybe a XR350 or XR400. Not sure yet. The 200 motor runs but smokes a bit. I'm sure it needs a rebuild.

    Glad you guys are here. This this thread has helped me a bit already. I could only imagine how many others this helped.

    The Clarke IT200 tank might work. It is 2.7 gals. vs. 1.7 stock. Came across one and decided to give it a shot. Here are some photos of a quick test fit with no modifications. This has got to be the closest cousin that is out there. Notice how the indentation in the rear of the tank matches the BW. The IT200 frame was a little funky, so the wider BW frame isn't an issue. It will require slight relocation of coil and some type of custom forward mounting tabs.

    This tank is a square faced tank with fork indentations. They don't match the BW, but the square face and set back means the BW forks don't touch at full lock. Only problem looks like the possible need for a cosmetic white cowling in front of the tank to reduce the visual impact of the larger amount of exposed frame. (The IT200 sort of has that too.)

    Found inside my BW350 gas tank. Is it supposed to be there or is it something being smuggled or ? It's like 4 fishing weights inside a plastic bullet shaped thingy.

    Also, are there carb rebuild kits available for the 350? Got the carb off and it's a mess.

    Thanks,
    Duster

    Looks like a fuel catalyst such as a fitch or something like that. It is supposed to do wonders for your fuel (If you believe the advertised claims) like increase fuel mileage and lower octane requirements. Do they work, I doubt it, but I have never tried one either.

    That's what it is, I'd never heard of such a thing.

    I'm going to venture a guess about the green wire because I have a broken green wire on my harness. Everything is working normally and that leads me to think that it could be the ground for the switch that prevents the bike being started in gear or without the clutch lever pulled in. I bypassed mine, so it would leave the wire without a function.

    My short search for a 200 wiring diagram has left me empty handed, so this is pure speculation.

    Regards,

    Mr. BigWheel

    Sunday arrived with blue skies, moderate temperatures and a pair of kitchen passes. So Cliff and I started off the day with The Breakfast of Champions:

    [​IMG]

    We drove to the Jim Creek trailhead, where we received numerous stares from the Rhino/Razor/fourwheeler riders that were populating the parking lot.

    Spring has definitely taken hold, as evidenced by the rushing meltwater and open streams along the route:

    At the half-way point to the Knik Glacier, Cliff noticed a sign advertising "Free Mud Baths - Today Only!!!!!" Not being able to pass up such a sweet deal, he dove in headlong:

    Just to show what an epic faceplant it was, here are some shots of his helmet and goggles that also got the spa treatment:

    It turns out the the free mudbath wasn't truly free. It came at the cost of one brake lever. I guess Ayn Rand was right.

    [​IMG]


    However, riding around without a brake lever is something that Cliff has become quite accustomed to, for some reason (ahem).


    Refreshed by the break, we continued on to the glacier. As we rode over the terminal moraine, the tracks became fewer and fewer. Out on the lake at the base of the glacier there was a single trail between the icebergs frozen in place. Everyone was afraid to deviate from the track for fear of breaking through and joining the mastodons and mammoths that lie beneath. Spring riding in Alaska is a sport for courageous idiots.


    That, of course, meant that we needed to ride up the side of an iceberg and jump off of it, since we were as far away from the trailer as was physically possible:



    [​IMG]



    That is how Cliff managed to exterminate his clutch lever. No clutch and no brakes, that's a FatCat, right?


    [​IMG]


    Cliff exposed his sentiments to the glacier and we began the long slog back home. Using only the rear drum to control the massive horsepower, we enjoyed the slimy ride back to the truck in the mid-forties temps that melted the frozen mud into a more malicious form.

    Watch out for these sukkas ! they will ruin yer day at 40 mph...
    Like a moron I was holding my camera going up the road as so many elk had been around and this one jumped out so quick i didnt see it comming..missed it by a good 6 feet though..one hand on the bars and lost a couple heartbeats..no more hand held while riding for me..

    BWSwamper, this is a pic of where the front lights went, tucked up high, very flexible and bright.
    Yes-still trying to figure the wiring ..
    how does a guy tap into a clean power line to run 12V?? anyone??
    I tried to install the tusk handlebar control to the 'headlight' main wire as their instructions and the bulb got so bright it looked like an aircraft landing light for 3 seconds and literally blew up-first time I had seen that happen...I dont know wich wire would do that ?
    The more I look at the diagrams the more I am hesitant o connect anything without further consultation.

    [​IMG]

    BWSwamper - that tank looks great to me, the exposed steering area has always been an eyesore, not that I picked this model for 'beauty' ..blends to the seat nice too..watcha thinkin' for a cowl?? like a faux tank extension to blend in??

    Just doing my part to keep the economy going. The Bigwheel aftermarket cottage industry is alive!

    RWBWheel,

    That's what I'm thinking. A white plastic cowl/faux panel to blend in with the tank and hide some of the steering head.


    It would need to be narrower than the tank (as viewd from above) in order to maintain the full lock steering. I have a broken BW front fender which might serve as material. Also, thought about using one of the soft white plastic marine vent cowls.

    I will save you all the long boring story about selling a bw350 and regret....

    So, I live in Minneapolis, MN and am looking for a BW350 at a reasonable price. For some reason the only ones I can find locally are priced over $3000.

    I have been searching craigslist and find a lot of BW350s around the country that are priced between $1800 and $2300. Heck, I even found one in NJ for $1300 but can't really justify driving that far. http://jerseyshore.craigslist.org/mcy/3743767122.html Maybe one of you guys can save it from the mentally challenged current owner.

    Let me know if you have one or know of one for sale that is priced at 2K or under and it is within 500 miles of me. It is ok if it is in rough shape.

    Thanks,

    Brent

    Brent,

    We all know that tale of woe and regret. I do think that the 350 on the Minneapolis CL looks pretty good though.

    http://minneapolis.craigslist.org/dak/mcy/3757256992.html

    Like anything else, you usually get what you pay for. The new gas tank suggests that the owner was willing to put money into the bike. Some of the parts look like they were painted for the sale but at least show that some care was invested in the machine. Often, these bikes are neglected.

    If you deduct the expense of driving 500 miles (which is a considerable sum these days) to get a cheaper example then you are getting closer to your price range.

    Best of luck.

    Hi I'm new to this forum but have been lurking on this thread for a while. I bought a BW350 a couple of months ago, it was very complete but had not ran in quite awhile. After cleaning it up I tried to get it running, but it wouldn't run well at all. I found out that the CDI was bad & replaced it. Also someone had tried to work on the carb & had screwed up the main body casting beyond repair. As you all know these carburetors are rarer than the bikes themselves. I'll show you what I came up with. A 2010 Raptor 350 carb with the choke lever from a 2012 Raptor 250 along with a Raptor 350 twist throttle conversion. I also had to modify the air box boot to accommodate the larger carb throat. I used a silicone hose adapter made for turbos. It now runs great, like a new bike with the stock Raptor jetting.[​IMG][/IMG][​IMG][/IMG]
