Hey everyone, doing a rebuild on a Stomp 125 pitbike just for a bit of fun and something to do on the nights when I'm bored! Before I started the project I had a quick ride around outside the garage and noticed something odd. The bike would ride mint, however when I wanted to give it some and got passed around 1/2 throttle in 1st gear, it almost felt like I was hitting a rev limiter and the bike would just scream but not move until I shifted up to second if that makes sense? I'm wondering if this could maybe be a slipping clutch that needs adjusting? If anyone that has experienced this could give me some ideas it would be appreciated!
