Hello Johan . Have you checked your cam shaft lobe is not worn off to one side ? The spring that holds the rocker onto the pivot , is it hooked in correctly ? Those L28 motors loose lots of power if their tappets are not set nicely ! Now do you know your L28 cam can be set for: torque , mid range , or top end ? (setting 1 , 2 , or 3 on the cam sprocket). Now I hope that helps you in some way . Cheers for now guys .
Can we get rid of STUPID DRIVERS before they kill us ?
