Ok.. I have installed the BBk, I know I am TDC. I adjust my valves and I test drive and the lash keeps changing. did this 4 times already. I did notice when I adjusted the last time , I did the intake first then the exhaust, when I went to recheck the lash the intakes gap was closed and had to do again. and every time more than usual valve tapping while running. the rocker arm tappets are not striped and it is the right head and rocker arm set. not understanding what is going on, I have done about 10 of the bbks and never had this problem.

Seems to me, something in the rotating parts is slipping, since valve lash is changing. Is it the stock cam or a new HP cam? Did you replace the cam bearings? I have no experience with BBK kits, but I have done plenty of valve adjustments.
Is it a normal GY6 mill? On my Genuine Buddy, I have to remove the sprocket on the new GY6 HP cam and press on the sprocket from my old stock cam.

Ok, Sry for the long pause , been working lots, I had a bad rocker arm set. I have a new prob., I have my lash set at 002 intake 003 ex. when I try to crank by starter it turns slow.( Battery is good ) I can kick it one time and fires right up. I drive to store, cut it off and it takes about ten kicks to get it going while hot. also it seems when it warms up I stop at a light the idel stays at a higher rpm (somewhat above normal) on the first crank via kick, it will idle at the normal, and don't ramp up for the worm up, I tried the lash at 004 on both sides both sides, too much chatter...Any idea what is up.

the starter can either be full of oil from a bad O ring the brushes are worn out or both.
if you have hard starts when warm try an extra .001 on the valve
its helpful for all the oil seals if you run a vacuum to the crank case
the hose on the valve cover is what you want to use for that. Just run it through an oil trap first or you'll crust up the valves with carbon.
