The 13 second scooter

We have all heard the term '10 second car' thanks to the fast and the furious film series, well heres a new one for you.......... '13 second scooter' sounds like a dream but its very much a reality.
Right now in the workshop im working on a engine thats going to fulfill this very purpose!.

You probably think im just going to shove a T-MAX 500 engine into a bicycle frame, but you would be wrong.
Im actually using a humble Yamaha 125cc engine............... modified of course and using an actual  road going scooter frame!.
I wont be using a turbo, supercharger or even nitrous, this engine will be 100% N/A.

So how are we going to do it?
With some love and care we can bore and stroke the little 125cc to 331cc, yes thats over 2.5X bigger.

Now the tricks needed to stop the engine from exploding in to a ball of flames after 10 seconds i cant reveal, but i can tell the specs:

• One of our special pistons at 75mm diameter
• A extremely strong CNC 17mm stroker crank with a mother of a connecting rod
• Special high flowing 4 valve head
• Titanium exhaust (for weight reasons)
• ceremic coating everywhere
• No water cooling!!!!!!!!!!
• Extreme high compression
• Special gearing set for the 1/4 mile
• 42mm carb......... not decided on the type yet

I already built a junior version of this motor in 280cc guise and it ran 14.2 seconds with a 220lb rider.
So unless this thing explodes before it reachs the end of the strip i cant see it not setting a 13 second time.

Im hoping this will become the new category for drag racing, right now the limit is 239cc, they made this rule a few years ago when it was about as big as you can go, but thanks to recent developments in technology over 300cc is now possible.

Pictures soon...........
