Yes that sounds familiar! My boys at that age loved the limiter noises on my old Atv, but now they are old enough to drive it! I fear it may not last the next 20 years as trouble free as the first 20... It's getting its now getting its 100 redlines a day....My 3 1/2-year-old daughter wants me to rev the engine pass 7k every time I bring her home from daycare in the garage. She is dying laughing. My wife on the other hand is getting seriously pissed.
