I have 2009 stock blast with 4500 miles. Have had it for a month now. Don't know if the owner before rode it in the winter

So it will turn over fine. It will just bog down then idling and warming up. I can give it throttle to keep it up and it'll stay idling fine once it warms up good, and sometimes it'll start fine and not die but still idle low when started but that's about it

I threw an iridium plug in it and it immediately would idle really really low and then die and I would have to watch it for a good minute and give it throttle to keep it running, so I threw in the old plug that same day since something isn't right. I just need some direction to figure out what to check and look for
