SOURCE: 620 Transmission Problem
Have you looked at the countershaft sprocket? Also check the chain for kinks... Countershaft sprockets bend and chains stretch or bend side to side, Me thinks you got ^^^^ The gear boxes are almost over built on the 620's It would be hard to damage them. You might also check the belt timing as you might have spit a belt off, Or forced it to hop a tooth. Pulling the timing belt covers is easy. The timing marks are marked on the cases and pullies. Just line them up with motor in top dead center. The older monsters had bad countershaft bearing that would fail. Great way to check for internal damage is to drain the oil and check the pre-screen. Good Luck

Your carburettors might be out of sync. You need to measure the vacuum
level of each carburettor, and ensure that they are the same.
I had similar problems, which were caused by a faulty ignition coil. It is also worth replacing and gapping the spark plugs, if this has not already been done.

The latter part sounds like insufficient play on the clutch lever--the clutch seems to be slipping. Sudden power loss is usually linked to the ignition system. Have you checked the lube level in the transmission? You could be having a bearing seizure if the lube is low.

More than likely the shifter pawl has broken. Breaking in 5th gear is kind of unusual however, they usually break between first and second.
You'll have to remove the outer primary cover to look at the shifter pawl. It's partially covered by the clutch assembly.
