Hi was searching Turner Engineerings site for something and found a conversion kit for £45 think it includes an oil temp sender and a genuine filter, it's in the specials section, worth a look.
Thanks 2 all, will try them. Just fitting a new clutch master cylinder mine packed up on the middle of a bridge! Had to get the rac out took over 3.5 hrs to get home and I was only 2 miles away! Said the landy was too heavy for them and had to get a recovery lorry out! That's landies for you.
i drove my 11A for 30 miles home with the same problem. just gotta get the revs right when changing gear. although stopping and starting is fun.
seem to remember have the same issue with my 1275 mini too. bloody british master cylinders!
