hi everyone, my first post! anyways ive bought myself a FZR400 and want to know the basics of how to maintain it properly. the fairings are quite a mess so ive taken all of them off with the intention of restoring/customising them. with all the fairings off ive had the chance to familiarise myself with the bike as i have no motorbike technical knowledge at all!! the oil is low so im going to change it so would like to know.... what is a good oil to use and synthetic/semi-synthetic? topping up the oil im guessing u fill it to half way on the sight glass? where is a good place to get spares, second hand and new? what is a good chain lube to use? and a few technical problems ive noticed are.... rear brake is shite, plus when i press the rear brake the brake light comes on yet when i press the front i get no brake light. anyone had his problem? clutch lever is stiff as a bastard, ive WD40'ed the lever but no difference. is it worth replacing the cable? thanks in advance for all responses and helpful advise
