Better move it. Those viking zombies are going to chop it to bits!

Nice! And yes I'd love to see the underside as well. I'll probably do something along the same lines with a GPZ-head for a Z1000J-engine.

[beachcomber]

yes - underside pix coming up  - just re-charging camera as we speak.

Time for blueprinting now. Nothing has been touched in the combustion chamber yet. With a blower polishing etc. doesn't really have any benefits for the amount of work involved, so it will just be careful matching and removal of any obvious "lumps". I always like to keep a full valve contact with blowers to aid cooling, so I won't be into a 3 angle valve job. There is just enough room for the second plug ! If I do another, I'll possibly go with a smaller dia. plug.

Vikings are there to guard !!!!

The next time you see this view - it will be shiny !!!

Uncharted territory  .................. what do we think guys ?

The second plug .... short reach plug so the threads / body on the inside [ nearest crown ] are level with the opening where it enters combustion chamber and remove / smooth out the threads on the other side .... or - what ??

Dual plugged shovelheads are similiar.  One plug is longer than the other.  Short reach plug on the second hole.

You never want the sparkplug threads to protrude beyonde the hole, so if that's only got depth for a short one, then that's the one to use.

Cheers,

yes, that was my thoughts Greg - nice for confirmation ! I'll "lose" the threads the other side where it's longer to get rid of potential "hot spots".

The belly pan finally arrived [ snowed in ! ] and I got the fuel cell mocked up. Works out at 2.144 Imp gallons with a simple shape. Also room for the battery and or some electrics - the fuel pump is one obvious candidate. Just need to offer it all up to the rolling [ almost ] chassis as POC. The fuel fill pipe will come up behind the engine and there'll be a cut-out in the seat for access - central oil tank style.

Not long now before my pal is off to the US to work on his property - so I need to get as much done as possible before he goes. I've commissioned a set of +20% stronger clutch springs - see what they come out at price wise. Oh yes and the wire is a far better quality than the OEM jobbies.

First POC fitting.  The fairing will go back 3" [ axle stands in the way ! ] and the fuel cell will be 3" longer giving me 2.5 imp gallons. Fuel filler tube will go at the back of the engine and come out in the front seat area - like central oil tank filler caps on Manx, Dommie and Gold Star. There WILL be a fuel spill funnel feeding back to the tank as the battery will still probably go under the seat. If there's enough room - it might fit in the belly fairing.

The fuel pump will go in the front section and the whole thing will be modded cosmetically to make it "right".
