Good spot Pigford yes they do protrude. Not sure why but they do !

The other interesting thing is the head has been skimmed offset. i.e on a slope if you look at the pictures below you can see how far the head has been skimmed on the exhaust side the skimming breaks through into threads of the exhaust studs.
On the inlet side its been left higher.
Apparently this mod increases the squish to aid exhaust gas extraction and increase compression whilst retaining the valve to piston clearance on the inlet side.

Did some further work on the bike this is what it looks like now.

Thanks mate but I'll stick with the 429's that are in it,

I would consider some 38/40 mm FCR's if someone has some as they may be an upgrade from the lectron 38's.

Ian, Thanks, I'll bear you in mind if I get something else lined up carb wise.

Just to make you really sick, the bike also came with an 18" 5.0 rear Dymag, :D :D :D
Bob with the Orange Gpz is trying to prise it from me. :)
