Quick action throttle

[stevierst]

Fizzy, its 35mm upvc plumbing pipe. Pretty standard 2.5mm wall thickness. Trim a piece to fit your throttle tube so its snug with no gaps or overhangs, then glue it in place.
It just needs a little bit of filing/sanding to make it fit without fouling the tube housing.
I've used it on two bikes now and its superb free mod, My fz1 is getting done next weekend. Have a go and fit it, if you don't like it, then just remove it!
