Right, im doing a project bought a cbr400 aero in bits engine in 2 parts and everything, now ive got engine in the bike, i turn it over and no spark... ive bought a new fuel cut off relay/... but ming you the start button doesnt work either and thats also new,,,.. Can anyone pleaseee help me!! im fed up of it and so close to throwing it on ebay....

Id start at the start button and work my way through. Is the battery in good condition , are the fuses all good.if you putt a spark plug and hold it against the block Does it spark?
Just work your way through methodically
Do you have a haynes manual ??
