Just got my 2011 125CC ATV back from storage, the ATV starts fine, idles great. But when I am in gear (The bike is a semi automatic with 3 gears 1 2 3 and reverse) the bike seems to be bogging out at a throttle. I cleaned the carb and it is still doing this. I need help ASAP because someone is coming to buy it next weekend and there are tons of work to be done and I don't want to do anything else until this issue is resolved. Thanks in advance.

 

clean and adjust the carb again. Its very easy to miss all the little holes in the needles and jets. It took me 5 tryes last time before i realized i was missing one little hole in the jet. Also make sure your choke is working properly and check your plug

 

What is the plug size for these machines? I am close to Canadian Tire and away from home and if I have the right size I can pick one up now then install it when I get home.
