Whirr Bonk???

Hi

Went to start the bike this morning and it went whirr bonk... It turned over for a split second and then made a loud  donk noise and stopped turning over. Turned off ignition, tried again, same thing. I thought the bike was dead but after a few more tries it kicked in and started but roughly. Bit of smoke out the pipe but it was early morning... After that it seemed fine. Any ideas what it may have been?

Flat battery? When was the last time you rode it?

Hi Pinheadplanet

Could also be a slight hydraulic lock which can occur if a bike has been left for some time on its side stand,petrol from the left hand float bowl can overflow into a the left hand cylinder causing the same effect.If possible leave the bike on its main stand or a paddock stand with the fuel turned off not on prime as the diaphragm in the tap should take care of the rest,if it still occurs from time to time it could be the rubber diaphragm in the tap perished and starting to leak past into number one cylinder down the vacuum pipe(you can rebuild the tap with a tap diaphragm rebuild kit.Good Luck
