Eventually got the bike in the garage to get the sprocket nut changed, also got the suspension wishbones done.
What a difference the wishbones have made, totally different bike, well chuffed.
So I went for 130mm bones in the end,I'm about 6 foot and can still get both feet on the deck but wouldn't want any higher.
Much more commanding seating position,more perched up on top,I like it anyway.
Well more natural position for my feet, was missing gear changes before coz I was so low but no longer.
Bike handling like a dream, turns in perfectly,more flickable,lots more fun indeed.
A bit far over on side stand, back wheel just about touching floor when on centre stand as oppose to couple inches off deck before.
I also set front shocks to 2 rings showing, set rear shock to hardest setting and 36/42 on the tyres.
Totally recommended.
