1970 BS200 resto (pulled out of a snow bank)
« on: January 05, 2013, 10:20:44 PM »
I found a BS200 on CL.  I asked my step son, who is 13, if he was interested in fixing up a bike.  I got the usual response for a 13 year old "Um, ya sure".  I then went into what is involved and that I was only going to be a supervisor and the hired muscle for those really stubborn bolts.  He actually still wanted the bike.  So we drove up to the guys house and started digging it out of a snow bank.  Once free, I gave it a quick going over and it appears the only thing missing is the left side cover, and made the deal.  $140 later we loaded it in the back of the truck and brought it home.  It's quite weird for me to be able to lift a bike into the truck with only 2 people,  all of my bikes are way heavier.  Once we got it into the garage I got to really look it over.  It seems one of those rubber intake things is shot and the other is not far behind.  The seat has been bedding mice down for years but the inside of the tank is in great shape.  There is very minimal rust in there and no dents on the outside.  We will have to re-glue the rubber on the side of the tank.  I have to wait for the ice to melt on the spedo to see how many miles it has.  The exhaust is in good shape and I think we will be able to remove the rust on it and it will shine up nicely.   The exhaust seems more robust than the cb750 stock exhaust I have been dealing with lately. The brake lever is broke and the rear wheel is seized but that could just be because of the chain.  The front wheel rolls nicely and the engine turns over, so I am hopeful it will start once I rebuild the carbs and lube it up.  I will be posting pictures once I figure out how to do it on this site.

Wow....... considering you pulled it out of a snowbank and it's obviously been out in the elements for a while, it's amazing that the inside of that tank is as good as it is.  :o

Are you sure its a 200? I think its probably a 175 unless someone changed out a bunch of parts on it.

The first two digits of your serial number will tell you the model. 16 for 175's and 23 for 200's.

Thanks for the link.  The add I answered on CL and it said it was a 200 and then this morning I had to commute to Atlanta to go to work.  I will get home tomorrow and I will check the vin.  I guess it really doesn't matter if it is a 175 or a 200 as long as it's capable of 65 to 70 mph.  Then at least I can take it out on the freeway.  How do people on this site feel about cafes?  I saw a 250 Kawasaki 2 stroke and it looked really nice.  But that's not up to me, the step son will have to make that decision.  Nice thing is what ever he does can always be changed back to stock.  I have built a flexible snorkel so when I get home I can sand blast the little rust inside the tank.  I have never seen a tank before that I can get to and see every interior corner.  I don't know about what color it was originally.  I have not had a chance to look into what colors they came in.  T.her seem to be some painted parts and some not.  I noticed this when I looked at the shocks.  One had a red top cover and the other is just chrome.  I do need a front fender, so if any one has one of those id like to make a deal and a front brake lever.  Other than that I am going to try and preserve/recondition what is there already.  I have never seen a seat like that.  Reminds me of a car seat with those interior springs.  I have a friend who makes custom interriors for cars so I will probably ask him to restore the seat and make a custom cover.  He can probably ever reproduce the Bridgestone logo for the back of it.

Richard Clark owns this site and has tons of parts. Search the forum for procedures on cleaning your tank. Also check out the manual section to download parts and shop  manuals. There is probably enough info in the forum to go through completely restoring your bike and if not just post your questions. There are ones on this site that have years of in depth experience with Bridgestones and are more than willing to help.

Good Luck and have fun! Mine was in worse shape when I found my 1970 DT 175 a year ago last Nov.1. It's come a long way and I'm finally seeing some light at the end of the tunnel. You may have to be a little more patient than you'ld like but all of the parts are out there even seat covers.

Thanks,  I took a closer look tonight and it is a 175.  I also took the seat off and looked at the rear fender and I think I will need to get a new one of those as the old one is pretty rusted or cafe it and leave it off.  I pulled the carb cover off and the carb and oil pumps look to be in good shape but I wont know for sure until I get them off and clean them up.  The electrical seems to not be in bad shape but I will be pulling it off completely and building a new wire harness.  There have been some mods to the existing one and I think it's just easier to build a new one from good modern wires and clean new connectors.  It's nice there are no turn signals to deal with and it seems the electrical is minimal.  The one question I have is is it possible to put 350 pistons, cylinders and heads on a 175 lower?  I did a search for any threads about this but didn't find any.  Since I will be completely going through the engine and replacing every seal and gasket I though it might be a good time to upgrade to larger displacement.  Any thoughts any of you have about this would be appreciated. I also did purchase a front fender for it.  Prices for this stuff vary a great deal on ebay.

Sorry the 350 top end won't go on a 175. Even the 200 top end won't fit as the cylinder spigots wont fit into the 175 bottom end. A complete 200 motor would drop in though.

I found that out this morning.  I called Richard and asked him.  It doesn't pay to spend the cash for a 200 engine for the extra 25cc's.  So I will just stick with what's there and make the bike as nice as we can as is.  Thanks for the response though

Spent some time last nigh removing stuf off the frame.  So far nothing looks particularly bad.  The slide in the carb was stuck but came loose with some coaxing with a wooden stick and some carb cleaner.  I am still waiting for the carb cleaner to do it's job on the choke plunger on the other carb.  Air box looks to be in good condition with only one small dent.  I will see if I can hammer/pull that out.  All the cables are trash, every one.  The guy I got it from said they had it running 6 years ago but I find that hard to believe.  Some one put the wrong bolt in to hold the tank at the rear and someone has played with the wire loom.  But this bike is so simple I will build a whole new one for it.  I took some tin foil to the front rim to see if they can be salvaged.  I am not sure from what i have done so far.  It looks like there is some pitting left after I clean off the surface rust.  When you guys look at the pictures maby you can give me some guidance if I can ix these or if they need to be replaced.

Thanks, I will definitely come out and take a look.  You aren't a member of the VJMC are you?  Was that your 350 at the motorcycle show?  I took these pictures of the BS350 that was there.  It was quite the inspiration to get the step sons bike going.

I got the carbs pulled off the bike and now I have them soaking.  I am having one problem with the left side choke plunger not wanting to come free.  That carb has been in the carb dip for 24 hours and it still wont budge.  Anyone have any thoughts?  I was considering putting some heat to it and see if it comes loose.  I am also having problems getting the idle mixture/air screw to come loose.  heat to those also?  The oil pump did not want to come off either but it was late so that can wait.  I looked at the manual and it looks to me like it should pull straight off.  It pulls out but then it seems like there is something hitting and it wont come any further.  Am I doing something wrong?

I have good luck getting those chokes out with a heat gun. That old gas can be like glue but once you hit it with heat it softens it.
