my RE frame no.G21270 has a modification.
On the front tube immediately below the steering yoke,
a small flat plate has been welded.
The flat of the plate faces directly forward.
Could this have been for a side car mount?
I have photos.
The welding looks vintage.
Appreciate any help

I don't think it would be a sidecar mount, not substantial enough. It's more likely to be a home made mount for a steering damper or possibly a lock stop to restrict steering movement. Can you post a picture? REgards, Mark

Hello CANUCK,------- oh dear !!That IS a bit amateurish isn't it ??----It looks to have been been gas welded (Oxy-Acetylene ??) Sorry--- I can't help you with positive knowledge on this one..I'm with MARK M , it does look like some sort of steering restrictor, but you can see it's definitely NOT a factory idea !!!! For those who've never seen one before this is a good example of the BRAZED-LUG type of frame construction....the brazing being the thin, gold-coloured line around the joints......... Have a look at this }---------
http://lovelybike.blogspot.co.uk/2011/0 ... frame.html ------------ I know it's a cycle frame but the process is the same... With the bigger lugs/joints a much larger gas gun which heated the whole joint would have been used.......Hope that's not a Hi-jak ??

Canuck, I can't open the second picture, can you re-post the link please? The first picture shows that you have TWO modifications. The top item is a steering stop plate, actually from a 250cc Continental GT (so at least a Royal Enfield part!) and the lower one is unknown! I have just been looking in the Parts Book for the early 350 Bullet. Is your bike a Bullet or a Model G? The way you have written the number is confusing, the G numbers should start "G" but the Bullet starts "G2" so is there a gap in the numbers? The early Bullet had 2 head steadies, one front and one rear. This might be the reason for the lower plate. If you can clarify what model it is I'll find the G book as well!
REgards, Mark

Hello MARK M---- well, that's odd.... Just about an hour before you, I had opened both with no probs--- now I can't open that second one either !! Careful when looking for that "G-s**t, er Book" it might be a pleasant experience !!! Wink-Wink, Nod-Nod, Say no more !!!

Thanks for the input,
added more photos, one of the serial number stamping.
I painted the frame, the bare frame looks more like the modification
was electric arc welding, the other joints are brazed.

Looks like a mount for crash bars or some such thing. Time to get out the angle grinder and the crack test kit I'd say.

Canuck, that's a Model G frame. Look in the Parts Book online section here. The steering stop is original(ish!), I didn't know Gs had this so you learn something every day! I can't tell what year, you'll have to join the REOC to find out, they have the Factory records. Do you have the rest of the bike? At this time all joints were brazed, welding only came for some joints later. The plate may cover a crack, it's not unknown at this position. REgards, Mark

Hi guys-------- yes, on closer inspection, especially with those added photos, you can clearly see some slag. ie it's electric welding...I'd go along with the idea of looking for a possible crack...Given the age of the frame etc., plus as MARK M says}- it's not unknown in that position.
