V12 Z1300

This is Alan Millyards latest project, some of you may have seen some of his work already. The guy can do anything with an engine...or two. The first picture here shows the engine shell, wow!

The engine sat in the frame with the exhausts fitted. Note the frame has been stretched slightly(10cm) to accommodate the "larger" engine.

The tank after being modified to fill the frame.

The next set of pictures are the finished article photo's taken at Stafford.

The tank looks much better now.

I can see the frames been modified, hence I can only guess he'll have to do the same to the tank. But with twelve cylinders hungry for fuel he'll need a bigger tank anyway. Talking of fuel how the hell can he feed all twelve from on bank of injectors? I'm sure he'll manage it some how after all he's worked near miracles in the past. Given the extra cylinders and cams I guess he'll need more oil, will one pump do it? will the sump have to be modified to hold more? Where the hell will he house all those coils? Will the shaft take the extra horses? Is the clutch going to hold up? Can the single crank take the abuse its about to be given?

I will try to find out the answers to these and other question as soon as I can get hold of Allan.

Okay questions answered:-

D. Does the bike need a bigger sump and better oil pump?

AM. The bike will have no more oil:- the white metal bearings have all been replaced by roller bearings and the oil pump is more than sufficient to do the job.

D. Will the crank take the strain of the extra horsepower?

AM. It's a new crank home made just for the job.

D. How many CC will  the bike be?

AM. 2200cc because I've reduced the stroke length to 62 thus enabling the engine to rev higher. The loss of cylinder capacity will be made up by the higher reving engine.

D. What will you do to the clutch so that it won't slip.

AM. A guy in france is running a twin turbo, nitrous set up generating 200+bhp on a standard clutch, I will put slightly stronger springs in it.

D. How many bhp do you think it will generate at the back wheel?

AM. 200+

D. How will you stop the bike overheating?

AM. I'm using the standard radiator but upgrading the pump to a high pressure pump.

D. I can see it's fuel injected, however each injector is feeding two cylinders split at the manifold how will you get the supply right?

AM. The 13 engine is quite crude it just fires the fuel in to the manifold leaving the engine to suck when it wants it. The same principle will apply, inject into the manifold and the cylinder will suck when it wants the fuel. It's not like a modern engine injecting on the inlet stoke.

D. How much longer is the bike now?

AM. 100mm

I hope this answers any questions you guy's may have had, I'm sorry if I didn't cover everything but Alan only had a limited amount of time to spare me.
