cb 750f frame

while looking over my 80 cb750f the other day i noticed an something
that struck me as rather strange. about half way down the right front
down tube of the frame, theres a split. its cut clean through the
pipe. it does seem to be braced well with brackets and bolts. looks
safe enough i guess. looks factory, not home hack job, but is it?
whats this all about? should i be concerned?

Many bikes have removeable frame sections.

many thanks. i do feel easier but cant help but wonder these breaks in
the frame somehow contribute to that occasional 'speed wobble' that ive
experienced. ? brakets and bolts are all tight, couldnt be tighter,
but would welding them up help to achive greater stabillity? if welded
up, would engine removal be possible? i know this may be a whole new
can o worms, but i wonder....

 

It would be hugely more difficult.

Seriously, don't bother. The deficiencies of early-1980s chassis are
such that welding up the removable section would make no difference
whatsoever.

 

Many Honda motorcycles have removable frame sections and have no
problems from them. All of the Gold Wing line have them and the engine
could not be removed if they did not. I agree with all the others, do
not weld it up.
