I just happen to have a 1000 monster laid in stock as a doner bike for such a project such as this, My pal Mick (le fooey) has been hankering after making a super mono single for ages using a 916 engine, one of those coverted to a single made 110bhp at the rear wheel, with a chuffer as the rear pot it could top 125, gas it with nitrus oxide… mmmmm serious black line laying properties.. mind Mick would have to eat more pies, to keep weight distribution in the correct area, yet he looked so cool in my silver leathers the other day.. the technical back-of Fag packet drawing would lead to some discussion with the conrods not using the common crank pin, but these projects are exactly what life is all about, it stops the primary female figure demanding you take time to go shopping, especially on those days you just want to watch a gp, road race, or have a beer while working where parts can be crammed into tight spaces. very interesting, just think where the air tank blow off valve coud be situated exiting through a wopee cushon, (the disgust on little old ladies faces)….
Guys the drawing of the twin crank pins is rubbish, it uses the single crankpin, but it has you lot going.. I reckon total cost of conversion would be around £400. but the time spent in doing it from scratch 4 months@ say £30 per hour, that is the sting in the tail.

Just thought some of you might enjoy some links pertaining to these types of engine cycle.

I believe DKW used a similar idea back in the forties or fifties… I may have the manufacturer wrong, maybe NSU, but I remember the name distinctly- “Ladepumpe”. It meant “supercharging cylinder.” Very effective before supercharging was banned in GP bikes… As I recall, the bike was also a “split single.” Basically a parallel twin with a 360 degree crank and a shared combustion chamber. The supercharging cylinder was aimed forward, and had a very short stroke and large bore. I’m sure i have the details wrong, please forgive me, just noting I see where the idea came from, and it has worked in the past, so why not now, with our more modern materials and technology?

RMT, some people like 500 singles far greater than 1000 cc V-twins. Besides, don’t you feel pretty anonymous on one of those?

Nice job, well done but what’s the point ? An old Honda vtr 1000 Superhawk can make 115 rwhp and 72 ftlb torque with some tuning and will go 100k touble free miles………
