Your Brat probably has hydraulic lifters and no adj.ness.
Cameron's fix is good but requires a lot of work.
Try changing oil to Castrol 20w/50 GTX plus a half can of Mr Marvel Mystery Oil and a Purolater filter. Takes about a week to work it's magic but many have had "joy" with this method.
If you look a few pages deep in this board you will see other articles on valve noise.

Using the 44K directly to the engine will remove hard carbon from the intake valves and the combustion chamber.
The 1st step should be small drops to the instake while the engine rev's at 3000-4000 rpm.
The 2nd step should be a BIG amount of 44K and CHOKING the engine.
The 3rd step will be waiting 15 minutes while the 44K removes hard carbon from all the instake valves and combustion chamber.
The 4th step will be turning the engine on (the 1st try would be hard).
Use STP engine flush (follow the directions on the label) and then Replace the Engine Oil + Filter.
After that your problem should be solved.

I would be very careful running Marvels for any legnth of time. And based upon some bad real-life experiences, I would not use motor flush at all. I am not dissing anyone who has had success using these products, but I sure wouldn't make a habit of it.
Engines are desinged to run on oil, and anything other than good clean oil will cause wear. There are safer ways to get rid of dirt and sludge. My guess is that the benefit gained is far less than the long-term damage caused by these products.
Jus my opinion...
Good Luck, John

I looked at the earlier thread about valves and the discussion there was also helpful.
