I was going to try some of these, but may go a different route now. As Steve say £100 per pony?
I might try banshee reeds and stuffers.

It was dyno'd with the TZR reeds and 10mm spacers. PWK 28's running 135 mains It was running lean Changed to v4's with the 10mm spacers and changed to 140 mains It is now a little rich It was run on different dyno's on different days so figures not really compatible but with the v4's it made 2hp more at the top end The midrange was where the big difference was Now the thing is with the 10mm spacers and the thickness of the v4's the carbs are now 20mm further back so inlet tract is longer so this may be helping With the TZR set up it ran well and would pull well from 4k but from 5-6k you were waiting for the power to come in. With the v4 set up you can happily short shift between 4 and 7k all day long and it's not hanging around At 7k it's making 45hp at the wheel Steve |

Just looked back at the 2 graphs
On the TZR set up the torque curve went up till it got to 4.5k then flattened till 5, had a lull til 6 then picks up again
With the v4's it rises till 5, flat line to 6 then rises
So they took the dip out and reduced the bit where the torque is not increasing
Doesn't look much on the graph but translates massively on the road

Just a thought. The 0,6mm china copy should rev higher than the 0,4mm petal of the original.
I notice also a wall of rev limitation on my pv.
