Hi there, have a 2010 yamaha aerox, working fine yesterday was cutting around no problem, has sat at the garage for about 2 months unused, unstarted, this was the previous owner. However, the second time i brought it out yesterday it bogged out just as i started to rev, to the point that the engine terminated, from here on the electric start is just turning over and will not start it successfully. Checked the spark plug, its a good NGK one and is generating a good spark. Help. Thanks in advance!

i would renew or charge the battery, bogs you say. ? if you roll off throttle, will it still run ,,,,

I recon the fuel has gone off. is it injection or carb?
