Thanks for checking this out, I have done a bunch of research and will keep doing more but I'm going to need help as time goes along. If you don't care how I got the bike and just want to know what the deal is you can skip down to the second paragraph. For those of you who like the back story, read on. My dad gave me his 1987 BW200 we had growing up when I returned home to Colorado after a couple years in Arizona. I live in Virginia now and did not have room to bring it with me when I moved, but I'm shooting a moose in CO in October and will be getting it then. I am really stoked about the bike, I can remember my dad packing out an entire elk on it-- he would tie all the meat to our homemade racks and go a hundred yards or so, then he would loose his balance and dump the bike, then he would untie all of the meat, stand the bike back up, and tie it all back on, and repeat. Another time we went to the dunes and that thing would go anywhere, he could stop halfway up a steep hill and start climbing again no problem. As you can see I have a lot of nostalgic memories about the bike and so I'm glad he hasn't junked it. I was trying to figure out a color scheme before I started a thread and was thinking a black/yellow combo like the DT400 my dad has (that we also grew up riding) would be cool.

Big thanks to macbig2k1 for posting all of the sweet info on his various threads (someday he may even grace my thread with a post), as well as all those who have gone before me, pioneering the way to more fun with fat tires...

EDIT: Un-TRDL'd post. Will re-TRDL when the project is finished...

Don't know anything more than I also like the yellow and black color scheme.
Don't know about Colorado or Virginia but here the DMV might look a little closely at the Black Diamond tire during vehicle inspection at licensing time. "Now just where did you say it says D.O.T. Young Man?";) sti-black-diamond-atr-group-large.png

I thought I could be making a mistake with the D.O.T. thing. Good find, thanks for the correction.
Bikes from our past that trigger nostalgic memories do deserve to be resurrected.
If the 25 inch height of the Black Diamond differs significantly from the stock tire I would consider restoring stock final drive ratio via a change of sprocket(s) for optimal moose-packing.:rolleyes:

Luckily in VA the biggest thing I have to worry about packing out is a big ol' black bear... PICT0048.JPG
I am having my dad mail me out the certificate of origin so that I can try my hand at procuring a non "off-road use only" title so that my ducks are in a row when it comes time to plate it. Wish me luck!

Well, I just ordered my front tire (25x8-11) because Rockymountain ATV had one left on closeout and the steering stem bearings (so I could get free shipping). Also I found a guy in WA that will make a sleeve and install it for $200, so I'm thinking I will order my piston and have him do it. There is a stator/cover assembly as well as an entire wiring harness complete with CDI, relays, ect from an 05 TW on eBay. I know the stator and cover will fit, so I'm thinking it may be a good way to bring all of my electrical up to date but its kind of steep ($450.00). Any suggestions?

Oh good to know, thanks TW-Brian! For a few minutes I entertained the idea of going with a Caterpillar theme like this: cat2.jpg
which I think would be well suited to the Big Wheel but Cat isn't really significant to me in any way so I don't think I will.

The front tire got in today and I found the DOT stamp! WP_20160720_15_58_40_Pro.jpg
But then I got looking at the tire and realized it really balloons out on one side, like this WP_20160720_15_58_30_Pro.jpg .
This is my first time buying ATV tires so is this normal? the tire is definitely shaped like it was molded that way... Also progressive springs and seals are on their way for the 200x forks as well as just about every bearing/ seal I need for the rest of the bike. Oh and the piston, etc and some sprockets.

Thats a good deal on the forks/hub/rim. I just bought forks and front tire/rim for mine and was about that, but no disc brake. I got most stuff off Ebay, but your wise to go with a tw harness as the factory cdi box for a bw is around 200 bones by itself!
Any measurements you need before you get the bike home, post up and I'll help you out any way I can.
Also. I have a 22/11 on the rear of one of mine with plenty of room between the swing arm, so width with a 12 you should be ok, I'd have to measure for height if that's what you were asking?
They have a good low first gear for those big tires, not sure you would gain much with a 6 speed, but that's JMO. Looking forward to your build, and good on you for keeping it in the family!

Thanks Big6Lug! I am wondering if a 25 inch on the rear will fit, and I just saw a video of a guy that had an ITP Mudlite (same as the STI I want to run, 25x12-9 with similar tread) so I am thinking it will work... The gearing is making my head spin, the primary drive on the BW is 3.7 where it is 3.318 on the TW/TTR/XTs. That being said, I would have 50cc more grunt and I could play with the rear sprocket to maybe get myself where I need to be to still roll the huge tires. I went to the DMV today and the lady said she was going to have to call Richmond to figure out what to do... The bike is classified as a motorcycle on the title but it also has the dreaded "offroad use only" wording. She said she would call tomorrow to let me know, I may just need to take a trip to another DMV.

Big step today! The lady from DMV #1 called back and said she spoke with DMV HQ and the only way a "dirt bike" can be plated is by going through a "special construction" titling process which involves multiple inspections, fees and a bunch of paperwork. So I tell her no worries and head to DMV #2. This one is a "DMV Select" and so it isn't a full service DMV, so I'm hoping they might just get confused and push it through. This time the lady was concerned because it had been transferred multiple times on the certificate of origin and also the offroad use only wording. I try to get her to just give me a title and plates on the premise that if it really shouldn't be on the road than the inspector won't pass it. She says no way and isn't familiar with the whole special construction thing. Then I decide I'm already halfway to DMV #3 so I may as well give it a shot. This lady is also worried about the multiple transfers, I tell her you don't need to title it in CO if you don't ride it on the street, she talks to her manager and tells me I'm right and gives me the paperwork. 20 minutes and $60 later I'm out the door with a clean title that says nothing about offroad use and some temp plates, I must be living right!

So I ended up changing my mind on not doing a 6 speed... I bought what was supposed to be the bottom end to an '87 TT225 and when I got it in the mail today I realized the rotor was not the older style so I decided to run the engine code past Yamaha USA and it turns out it's from an '03 TTR225. That should make updating the electrical a bit easier, as well as give me the extra gear with a wide ratio, plus 10ccs more displacement due to the longer stroke! Also I got in all of the bottom end bearings and seals (which luckily fit both motors as I had purchased all of them with the '87 motor in mind). I also picked up all of the parts needed to rebuild the crank and I'm thinking for the extra $100 or so dollars it might be nice to have it balanced, maybe it will help compensate for how terrible the rest of the bike will feel on the street...

Just wondering , if the BW uses a jack shaft for the rear sprocket then why can't you just drop in a XT250 motor and harness? Just thinking out-loud.

I don't believe the motor mounts the same way (BW uses motor as a stressed member whereas the XT250 is a cradle design), good thought though!
