Ok went to pull the "magnum motor on sunday but ran out of time. I did take a pic of the oil filter housing with the cooler explains the longer tube. Now this one got me we pulled the timing cover to make sure the belt was on right, it was. The thing that really caught my eye was the upper timing gear was like billet like a sprocket off a high end dirt bike only with the belt grooves on it. The valve springs are normal, stocks are like a progressive spring tighter coils on the bottom and spread more on top. We got the motor to fire but has a rod or wrist pin loose so we didnt try any more, didnt want to hurt it. So now we need to pull it and see whats inside. Ill post a pic of the oil housing.
