Hi Guys,
Once again, I really appreciate the input and advice.
I did think of heating it up, but I haven't got to that level of manhood where I have a torch that could get it to bending heat!
I ended up finding this one
https://www.amazon.co.uk/gp/product/B08CXTH2SM/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1
Which as you can see is miles longer than I expected, but it has a much longer sleeve where it fixes to the shaft so therefore offsets it from the engine case by a good healthy amount. And for £18 its not so terrible.
So although it has required my heel to be on the peg when shifting and an afternoon riding about to get used to it (any excuse to get out!), it has solved my problem, with the bonus of keeping the original for when I sell on.
Appreciate everyones input, I'm sure I'll see some of you round for more issues that crop up!
Peace,
Scrumpy
