As there's no chance of me ever racing her, I think I'll go for the 749R solution, thanks Jools.
I can see it being a bit more difficult to bleed as the air will naturally trap at the top of the loop, but some quick bleeding should do the trick.
Shame about the Dot4 fluid as I used Motul's RBF600 in my landy around south america and it's superb, if bloody pricey. Mind you she did weigh over 3 tons and there were hills where I though it was worth every dollar..
Cheers,
Ali
