Still Chasing RPM loss
I have two 1300s built the same, both have always run the same rpm and the same speed. Now all of a sudden one of them lost 50-60 rpm and about 1 mph.
Thing I have already checked include.
I have changed head gasket
Checked the reeds - OK
Checked and adjusted power valves - OK
Tried a different EFI controller - no change
Pulled pump and checked bearing - OK
New plugs side gapped and indexed
Checked Compression - still the same
Anybody have any ideas?

I spoke to Dave yesterday and gave him couple of areas to check.
