Finally some good news. My fuel cell has been welded !! Haven't seen it yet, but my pal that got it done for me says it looks the biz.

Now if I can persuade the same guy to get my headers welded up  .................

Tracking down a DARC-2 ignition unit is now giving me a headache. They were as low as $200 back end of last year - now up to $350 !

That's the last big ticket item - the rest is down to ass'y and minor expenses . Oh, then there's the engine ! One of my engines is in excellent shape and I already have new pistons, rings, gaskets, and bearings [ all standard ] - so providing no machining is necessary - we're good to go. An exhaust cam has been modified for the inlet [ rev.counter drive machined off ], but this #1 donkey will be fairly mild and rely on the NOS and blueprinting [ and 40 DCOE Weber ] to do the biz. I've now ditched the idea of supercharging - so the 2nd engine will be turbo'd. That's definitely next year !

I'm now back into the 101 little jobs that need doing - brackets, mounts, controls .............

We got the headers bolted up on the mule engine in the frame and marked everything so it re-aligned.

Removed head and barrels from bike - and bolted headers back up again so as to use the head / barrels as the jig !

Worked a treat - all re-aligned and ready for the welder to do his thing.

Sneaky NOS !!!! There will be NO visible giveaway as the bottle, solenoids, etc are under the dummy Manx tank.


Started making up the Grimeca brake torque brackets - working down that list now !! ;)

And finally today - we set up my new compressor and blast cabinet in my pal's garage. Makes sense as we will be building my engines there ..... oh and the GS500 Suzuki Boardtracker !!!

the way you have the nozzles oriented you will be blowing juice out the carb not the best plan

unless this is just a simulation even with small jets it will be considerable volume

Thanx for your feedback - however - not even a simulation - simply showing where they will go. The foggers are simply placed in the holes to indicate where they will eventually be ! The weld bungs are being machined to provide a 25 degree angle towards the head - and the nozzles will be reversed 180 degrees. They wouldn't sit there on their own for the pix ! Additionally they will be indexed to provide a direct spray pattern into the inlet. Experience gained with 3 stage NOS on my 502 ci Ford Altered will give me a guide.

Thanx Luugo - it was hard work as I am NOT a welder ! I made the exhaust as a 3D jigsaw puzzle from random bends. Initially it was all held in place with gaffer tape until a pal was able to tack it ! When I get it back, work will start on blueprinting and mild headwork. I need a bit of work around where the 2nd plug enters the chamber. I have a theory regarding the flame path and the 2nd plug. twin plugging the head has lead me to come up with some improvements - Mk2 head underway !

If the central plugs are 3/4" reach, try using 10mm plugs next time to get a little more working space.  And unless the motor is running huge compression as well as Nitrous, you shouldn't need the second plug. That said, unburned nitrous when it does finally burn makes for a nice bang, so maybe it's cheap insurance.

CXman - keep the feedback coming. And the critique - never know when I've overlooked something !! ;)

Teazer - that's nail on the head time !!! I wasn't at all happy when the head came back VERY close to valve seat and I could just see hot spot / pre-ignition setting in !

I did ask the guy to machine for 10 mm plugs ...... hard to get good help................ It was a mates rates job tough - so what can you say !! ::)

Fortunately I have 2 more heads and the guy that will tackle the job this time knows EXACTLY what I want. And still mates rates !!! ;D

I have had quite a bit of experience in the past with my Triumph 500 and 650 motors with twin plugs. We learned quite a bit with them. 2 were blown / petrol - and 3 blown alky.
