Question:
Do you think the black bit on the side panel right hand side is decal ?
It goes from top to bottom.
(See picture)

We have discovered that the black stripes are decal (mad but true).
These should go in and follow the stripped indentation on picture ...

I am considering a re design and spraying these bits on the other side panel
if I can get the decals off easily. 9I usually can but these seem very gungy)

Big day tomorrow for the old bike !

MOT.
I can barely wait to re create my youth on this old bike !

[ukjules]

It passed the mot so is back on the road
BUT
I have a problem.

Currently it runs poorly at higher speeds .... 45 plu ..(ho ho)
(It has only a few weeks ago run ok all the way up the power band so this is a new issue)
When it was running fine i noticed petrol leaking out of the carbs air inlet
when i stopped. to fix this i started looking at the petcock and carbs etc.
I am now at this stage with all ok bar this spluttering at mid range speeeds?


start up and tick over it is absolutely perfect - it sounds spot on.
It as if it is cutting out or running out of petrol above 50mph ? like it does when it
needs to be out on reserve. Or the electrics are cutting out ?

I have taken the carbs off at least 10 times his week to fix this and am completely stumped.

-Valve clearances spot on
-plug gap ok - and a spark on both
-Carbs removed, dismantled and cleaned 3 times now in one week.
Various new bits stuck in.
-Tank removed - chemically cleaned and washed out - petcock not leaking and cleaned out.
-coils checked - both primary - 4.25ohms both sec - 11000 ohms without plug on
- both plug caps ok

what next do you think ? ATU , pick ups ? coils ? carbs ? HELP

Hi Jules,

Try and narrow the problem down a bit. Does it happen at a certain rev range or when you reach a certain speed? If it is at a certain speed, what happens when you change down a gear?
