Hi
I have spoken to Dave this afternoon and passed on your thoughts and advice.
First I must thank you -
GDAS24, davidscott, johnnyboxer and Richard Simpson.
It was good of you to spend your time replying and is very much appreciated by us, especially Dave.
He feels from the feedback that the 4.00 x 18 is worth a try.
He also fully understands the possible complications but is a very experienced engineer and has been riding for a long time.
We are going down to visit for a few days on Wednesday ( he is out riding !
)
So we'll have a look on Thursday and I'll let you know.
Thanks again,
Barry and Dave.
