Come on LIv, I only weigh 90kg how could I start the bike without a starter, quite apart from the fact that to get down the weight to only 228kg BMW junked the kickstarter

If I need the starter I also need the generator and as the generator only works when the engine is running I also need the battery

However, tell me more about getting rid of one cylinder

Will the bike look odd and be a bit unbalanced
I agree with the brakes comment I hardly use them compared with most people but it won't get through the MOT without them so they have to stay. Perhaps I could fit lighter ones and fill the lines with helium instead of DOT 4 fluid. That would be much lighter. I would suggest hydrogen, even lighter, but a fire hazard in the event of an accident
How much weight will I save if I take out 98% of the oil and will having less oil improve or detract from the performance?
