Evening. I own a mutt mongrel 125. Ive been having an ongoing problem with it. It seems when i first start the bike wether i leave it for a minute or ten minutes when i pull away in first gear and come to a stop at the end of the road the bike will always seem to cut out. Once ive started it again and got it going with a bit of lag and got going through the gears it doesnt happen again. The bike is fuel injected ive checked the air filter its had a new coil pack and spark plug and an oil change. Where do i go from here?
