SHIT......  i had the 175DT at that time.... Then every thing went away in 1968 with the draft......   now i have 10 bikes and lookinf for more....  Im not marryed to i don,t have any one to tell me NO....

thanks for your share.  Boy.  are you ever right about "Then every thing went away in 1968 with the draft......"

Jack was a classmate of mine, he was a wild half-Santee Sioux, after one too many alcohol/driving convictions, our local Judge Burton gave Jack a choice, either face some prison time (previous offenses were only jail offenses which were not working) or go to Viet Nam.  here is how the rest of that story went - http://www.vvmf.org/Wall-of-Faces/22109/JOHN-C-HAYES

           Nothing wrong with getting excited, particularly at our age, and many thanks for sharing with us the achievement of your teenage dream. We have no desire to censor or pity you, many of us here are are chasing the same goals and enjoy hearing how fellow BS fans reach theirs.
    Should have seen and heard me when the GTO arrived from the US 18months ago, I was 19 again. I was also attracted to the GTR when I saw your second picture in Cycle magazine all those years ago, best looking bike I'd ever seen, it's now my screen saver.
    Family took me out for a very nice Birthday meal last week and right at the end, surprised me with this. Really was 'the icing on the cake'.                         Brian.

O, boy Brian !  70!  i remember waking up one morning, sometime shortly before or after 60, and having a couple realizations.......  now i'm only 3.5 yrs away from 70......  sheesh.  time goes faster and faster, enjoy what we have, every day is a gift.

i know this is the Bridgestone site, but for the brief time being, please pity rather than censor me, as i am still so excited! (nice to still be able to get excited at age 66!)  i guess i would title this picture "Two Ill Fated Motorcycle Worlds Intersect or All in the Life of an Old Farm Boy."  After 50 years i now have both the bikes i wanted ever since i was 15.  i was never able to get the pictures in ads of these bikes out of my head; i got the Interceptor last year, it's a '67, and now the GTR!  One thing i have always thought cool about both bikes are the fully shrouded all chrome rear shocks.

   Quote;      '' At the age of 66, I have either become tired, or more sensible; hopefully the latter….''

     In my case, I think it's a bit of both, just hit 70 this week ( or rather it crept up on me :D).

    The 59mm Oring is a static seal on the outside of the labrynth seal and generally doesn't give trouble.
    Early 350s had two separate air filters located one either end of the cross engine airbox. These broke up and were abandoned by BS after many expensive warranty claims for wrecked engines. This issue does not refer to the stainless metal mesh you would find behind your green filter foam.
     When I said the chrome bores need all the help they can get, I wasn't saying they are a weak point but they are susceptible to scratching from any dust or grit drawn in under the piston. Make sure the airbox and carb covers are carefully sealed to extend the life of your engine. Richard has claimed the bores are good for up 100K miles, a member in South Wales bought a bike with 40K+ on the clock and found the bores to be reusable.
       Enjoy your GTR as she is, too good to restore and they are only original once.

Mine is the highest mileage 350 I've seen at 43,000+ miles, although there may be others out there. I've had it since '74 and rode it to work for many years. I use a modern synthetic 10w30 engine oil. Any modern engine oil is fine, even those with friction reducers. Since the BS 350 has a dry clutch, you don't have to worry about friction reducers affecting it as you would in the smaller BS bikes or any others with a wet clutch.

Karl, that is a great ownership story.  if you have a picture handy, could you post on my thread here?  What is the most major work you have done to it and at what mileage?  what are the biggest or most recurrent problems you've had with your bike?  i am guessing you pay close attention to its maintenance, so probably not that many issues...  i am sure the bike looked like new when you got it in '74, and has been pretty amazing to be a part of it as both of you age together.  the dry clutch is indeed a very nice feature, especially on a production 2-cycle bike.  i have been happily running Amsoil Interceptor in my little Yamaha, and other injected 2-cycles over the years, and i just put a quart in the GTR.

I'm with you - don't overhaul the engine or anything else unless there are signs that it is needed. Treat it as you would any used car or bike.  As far as the engine is concerned, I know from experience that cylinders, pistons, rings and bearings are good for 40,000+ miles.  The crankshaft has an aluminum labyrinth center seal, so no worries there. The rubber seals on the ends of the crank can be hard after this much time, but don't require an overhaul to replace. Even wheel and steering stem bearings should be good since outdoor weather obviously hasn't been an issue with your bike. You might want to re-grease those bearings when you get a chance because the original lube probably didn't survive very well.

Karl, thanks for your thoughts which is exactly where I am at.  I also appreciate your thoughts on the durability of the various engine components.  That is really good to hear.  The needle bearing top and bottom is same as the Rotary Jet 80 which I have seen a couple examples with over 20,000 miles on odo, and still running strong.  Reading your post, and looking at parts book, very nice to know there is no rubber labyrinth seal, I do see a 59 mm O-ring. 

What I have done in the past, when recommissioning a bike that’s sat for decades and is in obvious need of deep attention is to completely dismantle the bike, sometimes even pulling engine and clean everything, new grease in all pivot points, including steering head, swing arm, brakes, etc.  I have found it’s a lot easier to see what needs address when the  bike is dismantled this far.

However, what I am thinking with this GTR, because so far it seems in amazingly fine order, is I will probably dismantle in sections, e.g., dismantle front end, clean, grease steering head.  Then do the same with rear end at another time.  As it is, the forks are not leaking, so I am really reluctant to take apart or molest anymore than is necessary; as you say, treat it like a used motorcycle and give it what it need, and nothing more.  The other surprising thing, is I feel no detent in the steering head, so I can assume it is not dried out.  And, the wheels spin very very freely.  I think I'll take out a drain screw and see what for oil looks like, base on what i see, change accordingly. 

As I am sure you have seen in your projects, this bike does not seem to have the horrid things one becomes accustomed to seeing in a bike this old.  It appears pretty obvious the GTR has had good owners over the past 5 decades.  Pretty amazing if you ask me.  Something I have to respect.

The other thing I probably should address is changing transmission oil.  The Owner's Manual calls for an SAE 10/30 engine oil.  Is there better lubricant you'd suggest, an appropriate weight oil designed for motorcycle transmissions...?

Karl, it seems your association with the Bridgestone motorcycle has been a long one...? what are the highest mileage GTR engines you've seen still in running condition (that maybe you wouldn't have expected to be in running condition)?
