Early LiS headset question

[kalifornia]

I'm running a TS1 230 and am getting enough vibration through the grips to make my hands "ring" when I stop after about 60 miles. In an attempt to counteract it, I'm looking at putting some heavy bar weights into the ends and also use foam grips. I'm waiting for the grips to arrive so don't want to cut the standard ones off yet.

Can someone tell me what the internal diameters are of the bars please so I can get the weights ordered.
many thanks.

Not want you need but most bar end weights fit inside the bar, A Lambretta will have either the shaft with a spade type fitting that fits into the tube slots with no gap at the end. or a nylon plug with a roll pin through it. These will have around 12mm gap at the end. I made some bar end indicators and intended to drill and thread the shaft, to find mine had the roll pin, No drilling that bugger. I had to weld a small plate in the end of the tube then drill and thread that to fasten these

Thanks for that. It's the internal bar diameters I need to know. I've seen 22mm but also 7/8" and 1"????

I just wanted to order the weights so they turn up when the grips are here. I may just have to bite the bullet and cut mine off to measure them if no one knows.
