Called to see my spring man [ collect latest order for Kays ] and enquired re: KZ750.
He’s prepared to make a minimum of 40 springs as long as all dimensions are the same apart from length.
I thought maybe 20 of each B1,B2 … that’s 10 bike sets for each model.
As per the Kays [ Progressive, but without seals ] price would be £65 / set.
I’ll be posting up on the other relevant sites to see if there is enough interest to go ahead.
