Thanks.

Thanks

To everyone that had ideas and help with the carb questions.

Bike runs now.

It does however make a little valve train noise? Thats what it sounds like to me when you rev it up over about 5k or so a little vibration and some chatter but not to bad. I have heard of the cam chain tensioner making noises on these does it do what I am describing?
Also are the valves adjustable(sounds kinda like loose valves on a car)

Again thanks

Could be the cam chain tensioner. Those old style tensioners suck. In 99-00those tensioners on busas were failing left and right and lunching motors. Eventually they came up with an updated tensioner with an oil line to apply pressure to the tensioner as a back up.

Maybe your tensioner just needs to go to the next click. I am not sure on the old 600 tensioners if they ratchet the same. on the busa tensioners, you could pull the bolt out of the back of the tensioner along with the spring and plunger, then take a phillips screwdriver, put it in the hole pushing on th guide, you could force it to ratchet into the next click, tightening the chain. Then put the plunger/spring/bolt back in. Not sure if the 600 tensioner is the same though, they will usually/eventually click tighter on their own.

As for the valves, they are not "adjustable" they are shim under bucket. You have to measure the clearance between the buckets and the cams and use different size shims to adjust clearance.

I WOULD SUGGEST, taking it to Motorcycles Unlimited and letting them set the valves for you and be done with it.. They will have the different shim sizes in stock and the knowledge to do it.

Valve trains will make some noise but not clatter like lifters in a 350 chevy, usually the exhaust valves will tighten up and the intakes may loosen, causing some noise but......not usually.

You probably have a header gasket leaking some.

thanks for the cam tensioner info but I assure you it's not an exhaust leak.
