Hi all. Finding myself having not much to do with my evenings these days, I thought I would kick off a new and entertaining project for myself. I have purchased a Mini Dirt Bike. 49cc. Centrifugal clutch. Black. Chinese import job. Bought for £90 on ebay new. It's great fun to ramp about on, I'm lucky enough to live on a private road with a dirt track at the end, so I can legally ride it round . I am intending to make the little thing as fast as humanly possible, on a budget of £50. I have just bought the first parts today. Planned parts are: Bought parts - Air filter. £5.95 delivered. Uprated clutch springs. £1.99 plus postage. To buy - 'Rocket' key for timing advance. £4.95 delivered. Carbon fibre reed valve. £2.50 plus postage. Enlarged carb jet (0.75). £3.35 plus postage. Nitrous kit. £19.95 plus postage. I will post pics of the beast up later on... Watch this space - this could be a laugh.
