Dirt bike pitbike stomp APC chain tensioner roller

The chain on my Stomp pit bike kept slipping off due to a poorly designed pulley. To fix the issue, I designed a modified pulley with an additional 6mm offset, allowing the chain to roll smoothly and stay aligned. This adjustment ensures proper chain tension and prevents future slipping, making it a reliable solution for dirt bikes, pit bikes, and Stomp APC models with chain tensioner rollers.
