Alright I got a new 125 pit bike from powersports max for $450.00. I got it in a cuple days ago and put it together. So, I started ryding it and whenever I was going on high speeds and then slowed down it bogged and shut down and wouldn't start. And after it shut down i would have to wait 20 minutes to start again. Also whenever i'm going in a corner and dont have the rpm's high it shuts off after riding for awhile. Do you know if it's the sparkplug, air filter, any suggestions. Some info would be great.
