@brianpresnell Was replacing the broken valve spring hard to do? Did you need a special tool to change it. Help!
-
have the same noise in mine but after it warms up it goes away and have never as yet had any loss of power though....hope to heck I don't have to pull the head and change the spring, dang it, but it does have that same sound...it sounds like a loose tappet but who knows

adjust your valves

The pipe lying around and on top there is an SLS, but you know what it is?, since my GY6 engine has no such .. otherwise exactly the same engine ..
-
Dude, Thats to high Copression, you got 4 valve?, if so Both of the exshaust valves to 0.10 mm.
Check the engine oil, of it do work, sometimes chinese engines have a bad oilpump like this may do burst and wil stop working after a short time of use.. New engine oil? :)

I purchased a new complete head assembly which made it very simple. You can get them for about $65 on Ebay. There are two different styles, watch which one you buy. Otherwise you will need a spring compressor.

Also, the valve settings are .005 for both intake and exhaust.

I already fixed it. The problem was a broken inner valve spring. Rebuilt the top end and sold the bike. Thanks.
