The "NG" stands for "No Good" , Gordon.
You had better give the bike to me--I will be around on Monday to pick it up.
Well--with Brit bikes comes Brit humor!

Geeze fellers.....thank you (I think?) laughing

NG is what I thought too but to tell the truth I could never see the "G" correctly until I took a photo of it...it always looked like a "C" and I hadn't a clue about the "N" without the photo.

BUT.....we're not through yet. The "0" in O2648. I've never seen a "0" used at the front of one of those numbers...have you?

Engine's a good one and roars like a lion...I'm going to keep it one way or the other.

Thanks for the help.....Opie (aka Gordon in NC)

WOW Phil.....that couldn't have been better news. I think I'm going to be okay with the DMV....the photo is easy to read but in person and a tracing is very hard to tell what those letters are.

THANK YOU< THANK YOU< THANK YOU......Gordon

Don, the weather has been a mess and trying to deal with that and work....it's been hard to find time to run up and down the road. BUT we (me and the bike) are moving forward and I have made some progress.

With Don Roe's help I got the front stopper sorted and it's now a good un.

[Linked Image]

I gave up on the old Norton carb (I have another plan for it) and installed a brand new AMAL Premier carb....but haven't had a chance to take it outside and give it a try. (Shown here with the fuel level hose still attached.)

While I was swapping out the carb I added a choke.

[Linked Image]

And added a bar end just to be safe.

[Linked Image]

I was having some popping in the exhaust and figured I'd seal the head pipe. I'll trim off the excess once I've given it a try.


[Linked Image]

Got a tag, but not a title yet. The DMV was having some trouble reading the engine number but I think I will have that figured out this week.

[Linked Image]

Now looking at the tag it looks a bit tweaked....I'll have to go back down there and check that out.

I'm loving it so far....opie

Lookin' good! Nice selection of components on the controls, very tidy.
What width bars did you end up with?
Sorry, heard about your weather. Out here we just keep riding and praying for rain.

Don, the bars are 28" wide with a 2" rise....not sure of the pull back? They work well with the position of the footpegs.

[Linked Image]

The controls are aftermarket ATV bits....waterproof and made with high impact plastic. I use the turn signal switch for the pilot light.

[Linked Image]

[Linked Image]

IMO a LOT better than what I started off with.

[Linked Image]

Man, I think you're right about the rear fender. I went to a LOT of trouble when I first mounted it. Then I took it back off when I was wiring up the tail light. Added a couple more bolts up front but was so focused on the lights and wires I didn't pay a lot of attention when I tightened it all down. I just added the tag and made sure it was square with the tail light.....hadn't seen that tweak until tonight...and I bet you're right...it's the fender. I like easy fixes. blush

Loosen it all up, re-tweak and tighten. It'll come around.
Bet ya can't see it from the riding postion.
Those are some narrow bars. I run 33" and up on my bikes.
You must have hit some trees somewhere along the way. Woods bike eh?

Yea....I think getting the fender back where it needs to be will be a quick and easy do.

Bars????? laughing I'm guessing it's more what you're used to my friend. Measure up a set of Victor Special or Shooting Star stock bars and see what you come up with.. wink

Now keep in mind my first bike was a 1965 B40 Enduro Star and the first new bike I purchased was a 1968 Victor Special. I haven't strayed far away from those kind of bikes for all these years. So when I sit on one...28" feels about "right".

The B44VR Tug has a wider set....but I still think they're closer to 32".

You know what the women say "short reach, long peter" laughing

LOVE that photo you posted of the bike at the over look....makes me miss the high desert.

I am not too sure about the singles but with the twins BSA adopted the initial zero from the start of the 1970 season onward. As Andy and others have confirmed, - it is a perfectly good number. The chap stamping the date code letters on could have possibly benefited from a little more breakfast that morning.

Here is an image of the factory dispatch book.
You can see that it has a leading '0' on the frame number.

Mr. Gray,....That`s a swell B-50 you`re creating. I get the vapors when I see one done that nicely. This is a bit after-the-fact info, since Mr. Lorenz brought the proof, but the 0 in the I.D. has been on all `72 & `73 MXs I have ever seen,...except for the ones that have 00 prefix. I have a `72 and a `73 that are both thus. `71 MXs all (I believe) start with 1 in the 5 digit run. I`ve no recall of the Ts or SSs. Haven`t before seen a Victor 441 paint scheme on a B-50 tank...and I really like it. The SS front wheel is a nice touch. If you find you desire a little smoother shifter action under load, replacing the inner clutch door seal with a sealed bearing will make you smile. I assume you retained the `72 MX cam, as it`s the only model and year that had a special numbered, hairy grind...same specs as G.P. Victor. But I digress,...your machine is sweet. More photos?

Hey G-
Been sorting out a single carb 650 myself - It too has a new AMAL. Was getting a lot of banging in the exhaust. Jake H told me that with the new carbs, he's been having to screw in the air screw to about 1/2 turn out from seated instead of the usual 1 1/2. Worked for me.

Gordon,
When I went to DMV to register and title my B50, I used a little politics with the inspector. He just wants to be sure you didn't steal the thing so I humored him. Did you have to secure bond? That cost me a few bucks but I now have a good NC Title.

Mr Mike

Mr Mike, the fellows from the theift division have been to my house several times so we kinda have it down. I took a tracing of the numbers in to show them (that's how we get started) and they just rolled their eyes at that engine number.
I don't blame them I couldn't tell much about it either.

I didn't get a chance this week to deal with it but I should next week. I leave the bike in the driveway and they swing by and take photo's of the numbers and the bike. I have the old titles for both the engine and the frame so no, I didn't need a bond.

Pokie....I should get a chance to ride the darn thing this weekend and will post a pic or two then....thank you for the kind words.

Gordon in NC (aka Opie)
