Just found this searching for something else ..........
It's a road racing engine :eek:
Three enterprising Third Year students of Sou Venutai Chavan Polytechnic (S.V.C.P.) Pune, have built an amazing Three-wheeled ALL TERRAIN VEHICLE (3W-ATV) as part of their final project for their Mech. Engg. diploma.
The power-plant used is a stock 4-speed Yamaha RX 135 engine. The three- wheeler uses two 10-inch rear wheels and one 8-inch front wheel. Front suspension is on modified twin forks and rear mono-shock suspension is taken from Fiat Padmini. There is no differential used on the rear axle, which is driven by a conventional chain-sprocket set. A disc brake is used on the rear axle.
What needed development and fabrication were the axles, swing-arm and, Expansion Chamber to boost power. A K&N filter air was used and corresponding up-jetting was done in the carburetor. Details can be seen in the accompanying photographs.
The ATV was tested on absolutely kuccha lands of loose earth, steep slopes, mounds of gravel, un-even levels and other un-hospitable terrain, and it traversed all these obstacles easily. There is no reverse gear in this ATV, and to move it backwards the driver has to turn the rear wheels backwards with his feet as shown in the picture. The ATV can also do Front-Wheelie as well as Side-Wheelie as shown in the pictures. However, this needs a lot of training and practice.
Compared to the regular four-wheel ATVs advertised and sold in the market, this is a much simpler ATV and handles all kinds of terrain with ease. The cost break-up of this vehicle is as follows:
Engine Rs………………………………….14,000
3 Tyres Rs…………………………………17,000
Rear disc Rs………………………………..5,500
Front suspension Rs……………………..15,000
Rear axle Rs………………………………..5,000
Expansion Chamber Rs…………………...2500
Wheel flange Rs……………………………4,000
Swing-arm Rs………………………………2,000
Rear suspension Rs……………………….1,500
TOTAL Rs.6,500
