Look for worn teeth on the sprockets, particularly the countershaft sprocket. They become shark fin shaped and the chain can slip. The chain really should be checked while setting on a bench by measuring the stretched out length against the pushed together length. Another more crude way is to pull the chain off the rear sprocket at the back and if you can see half a tooth under the chain plate it's likely worn out. I've also seen loose engine mount bolts that let the engine swing back when accelerating which makes the chain loose so it jumps teeth on the sprocket.



Shift fork damage is usually caused by stomping down or up hard on the shift lever but it takes a lot of force.
