Thanks for flagging this up Mr.Seeker.I've been watching this E10 progress.As I run fuel cleaner I'm hoping it will nullify any problems with my Curvy.I've had none so far with the 5% and never get stale fuel either when my Curvy has been laid-up.
Since my recent little Carb-re-balance and plug check and clean my,"99" is running so sweet it's magical and mega,"Smiles for Miles
PS
You are right about some of the later design decisions on the SVs.I don't think I would like living without the excellently substantial and well placed rear grab rail for pulling my Curvy onto my Paddock stand :/
