Just bought a 2009 Buddy 125. Well, the wife bought it

I ride a Burgman 400 and she thought it is too heavy for her. Hence, the sea-foam-green Buddy.
I test rode it- only 314 miles! It seems to bog at WOT and doesn't go fast IMO.
So I'm thinking, carb full of cheapo gelled gasoline? Heck, 314 miles in 9 years, that's only 3 tanks of gas?
Once we get it home, I will tear into it. Planning to change engine oil, gearbox oil, adjust valves, check drive belt and variator, and R&R carb. Etc.
For sure, will post tons of questions.
Oh- does Dr Pulley make sliders for this thing? I put DP on my Burgman and they did wonders

Also, does thing have a choke? Feels like the choke is on...
