The Diff Frame

Prototype Diff Frame

New design of frame this time mounted on the underside of the subframe and passing under the engine leaving more space to get the engine in the correct positions

Clearance on the Subframe for the Sprocket

Driveshaft Alignment

Diff assembly in the car

Using the mini driveshafts the diff assembly was fitted in the car. We decided to use Jason's mini minus for the mocking up as the removable front end would make things much easier.

The sprocket lined up very close to the rear of the front subframe and would take some more work to get it in the right position

The Assembled Diff Assembly

This is the diff and sprocket assembled and ready to be fitted to the car. We have opted for a 2.733 final drive. This was acheived by using a 15 tooth sprocket on the bike and a 41 tooth sprocket on the diff assembly.

The assembly is a fully sealed unit with a split sprocket for easy of changing if required.

The rear sprocket is 216.299 cm in diameter (8.515 Inches).

The Sprocket and Diff Assembly

The Chain driven diff assemby was purchased from West Garages , Scotland. This kit seems a sensible option as it utilises the mini differential , the mini output shafts and therefore the mini drive shafts. We hoped by using this kit we could keep the costs down and make the job a whole lot easlier

The R1 5VY Engine

The engine is purchased. We went for a 5VY This is the 4th generation and was launched was launched in 2004 .This engine is larger than the previous models, The engine produceds power up to 172bhp.
We were able to obtain this engine from Isle of Man and paid a heathy £1000 for the engine, loom , injection system, exhaust headers, keys and ecu. Provided with the bikes background and history it was clear this engine was going to be perfect for the job and was in mint condition.
