here's the skinny
i changed out my CCT's and wouldn't you know it, it fixed it(the slapping noise) but now i have a tick during a load and backfiring during heavy load and i have a great loss of power.
my thought is that the timing chain skipped a tooth when i changed out my CCT's, unless there is good reason out there that is what i am going to go with... if you guys agree what might be the best way to do it and is it hard(time wise)?????

If they are manual CCT's there is a possibility that you over-tightened them (as stress on the cam chain would cause the motor to bog down). Careful when adjusting, a member tried backing it off a couple of months ago and went too far and motor blew up.
If it were me, I'd take the valve covers off and see what's going on in there. This way you can check the chain tension and timing in one step. I'd plan on an afternoon's worth of work if you've never done it before.
It's not particularly hard and doesn't take any special tools other than a couple of sockets and screwdriver.
You may have just saved yourself some serious damage if that slapping did go away

yea the slapping did go away which was such a relief for me but when i herd it start doing what it is doing now i was pissed. untill i can get it running right and i check it all out i think it is best i stop riding it. it only has a big issue when i get on it, it then back fires and is sluggish. they are OEM CCT's so shouldnt be a problem. the sluggishness started after i changed the cct's along with the backfiring.
tank and seat have to come off right. fairings too? do i have to replace gaskets?

You won't need to replace gaskets at all (there is a rubber one on each cover, but those are re-usable)
Can't remember if you need to take fairings off (mine have been off for a long time) but I think that they can stay on...
Seat and tank, yeah. You'll have to disconnect the oil cooler mount from the frame. What you're trying to get at are the four bolts that are holding the valve covers on. The front is much more tricky than the rear...
Once you get the valve covers off, you'll be able to check the timing.

yes i changed the CCT's without pulling the covers. yes i kinow (dumb ***) but i thought i could get away with it by setting top dead center before i did it through the inspection port. some of us have to learn the hard way. atleast i took the advice to change out the CCT's that was for sure a problem but i herd so noise when i cranked it up the first time after that but nothing else. my noise was gone and the bike now idled very well... but found out yesterday that i have no power on takeoff and it backfires through the carbs during heavy acceleration. i will be pulling that stuff apart tonight, once it is done i should be as good as new.

i am not worried about doing it. i have built motors and bikes many times. i just never worked on this bike and did not know if there was a quick/easy way to get to what i need to work on........

ok here is the update to the cam timing adjustment.... the front cylinder was just fine (a pain in the a$$ to get to, let me tell you!!) the rear cylinder on the other hand was so f-ed up i dont know how it was running. but i didnt make it any better lol i used the wrong stroke TDC mark. so now i only have 2 more strokes and one of them has to work. LMAO

they do look like that but they where adjusted on the wrong stroke. you can turn the engine 3 revs and have different locations on you valves so i am sure i just adjusted at the wrong stroke of the engine. simple fix, atleast it is the rear cylinder and not the front one. i guess this will teach me to not follow directions next time.

problem solved, thanks everyone for your help.
adjusted the cam one more time and it works like a champ.
still had a little rattle during acceleration but after reading some forums i figured i would try a few different things. the first thing i did was check my drive chain and wouldnt you know, it was loose. i tightened it up and sure enough noise is gone. now i have a little tick, i think it might be the carb valves, i can deal with that for now though......
I LOVE THIS FORUM thanks again everyone.
