Check your carburetor rubber insulator. If it gets cracks on the top air will leak in, run lean and backfire on decelleration.

so i checked the carb boot on my scooter there is no tears no leaks..
my elite 250 only does 59mph which it should be going quicker than that...
i did a valve adjust .. still no change

symptoms: popping on deceleration, loss of top speed.. doesnt run hot but the exhaust crackles like its hot

idk what to do
