Hey all, new to the whole forum thing. I have weak bottom end power and low top end speed. I Put together a magnum using Xplorer parts. The transmission and primary clutch are out of the Xplorer and the rest are magnum parts. All the sprockets are the off of the magnum as well. My thoughts are a primary spring? I have minimal knowledge with clutching. Tia.

 

Magnums have never been noted for their speed as they're designed as a utility/work machine. Gear cases are similar to the Xplorer,but the over all gearing may be different. If you're still running the Magnum clutches a spring change or kit may or may not help,but if you believe every thing from their description you can see if works out for you.https://epiperformance.com/magnum-3/
