Discover 135 - Engine bore question
Hi Guys,
I'm a Happy owner of Bajaj Discover 135 Bike, which is an aged but still stylish and sexy ride!! I have done almost 68,000 K on it and recently (a few months) the oil levels dropped half from service to service (2500km - 3000 km).
When I asked the mechanic, he said it was time to rebore and overhaul the engine. So after studying the engine for another service (This time I filled 1300 ml of oil) and still after 1500-2000 Km the engine oil levels dropped half.
I put my bike last friday for the overhaul, and when I visited the garage, he showed me the re-bored engine block, and the original spareparts he has baught for replacement. He said the old bore was 25 and the new bore is 50. is this 25 / 50 is in mm?? or is it a code to recognize piston sizes?
if it's actually a size like cm or mm, increasing the bore to 50 means double fuel consumption? Please advice.
