Hi Loudoun,

I cannot help with the speedo but I would speak to the person who restored it.

The mudguard looks like it is sitting a bit high and the rear frame loop seems to be missing.  Attached pages show front mudguard fittings and I believe yours should be like the bottom one.  The other page shows the rear frame loop which helps to support the rear mudguard.

Dave.

Hi don't aiways assume its the speedo if its been refurbed I think it would have been run up to speed on his bench before sending it back but could be wrong, have you fitted a new drive cable I fitted a new cable and had similar problem but mine was the cable was a shade too long when it entered the speedo head putting too much pressure on the workings and slowing it down and could damage it, as for drive it depends on what rear wheel size you have. hope this might help Roy

Good evening gents, had a nice ride this evening, Speedo still not behaving, I did check the cable the other day that seems fine, does anyone know what the ratio should be on the speedo and drive? Also developed a hesitation on acceleration seems like it's holding back then runs for a while it seemed better when I first started her up then the hesitation started. Might have to clean carbs out?
