Re: The car. was flooding Isprayed carb. cleaner in...
If the shavings are black and brittle then you can safely say that they are from your piston rings, this could be due to the bearings or just general wear and tear. if they were stuck to the magnet inside of the sump then it will be bearings and your engine will be on a self destruction mission the more you ride it till you get it fixed

I'm curious what you mean by a "plastic" cam?
Do you mean the breather valve in the cam chest cavity?
You said you, "replaced all the gaskets around the intake ventricle"
How are the seals where the intake manifold meet the cylinder heads?
These are notorious for leaking/sucking air.
Even if you twist the intake manifold (like trying to wrestle the carb off the manifold) can tear these seals, causing them to leak.
While the engine is at idle (or as close as you can get and still maintain it running) spray some of your carb cleaner around these areas, and see if the engine speed changes, indicating a leak.
Hi Anonymous, oil leaking from your air cleaner is caused by oil carryover from the engine. For what ever reason the breather system is not seperating enough oil mist and air from the piston downstroke. There are cheap and quick easy fixes and there are more exspensive ones. Start by trying the following:
1. Run your oil level half way between the add and full mark when hot.
2. Run oil breather lines from head into a TEE fitting below carb/induction module then a single line into a mini filter under frame.
3. Purchase Arlen Ness Super Sucker.
4. Replace umbrella valves and realign oil pump
5. Upgrade oil pump and cam plate
If This Engine Has Rubber Boots Between Carb And Intake Port(Head) The Clamps May Be Loose Or The Rubber Boot May Be Cracked Or Permeated( Leaking Air, Lean Condition). Never Use Starting Fluid To Test It Will Wash Oil From The Cylinder Wall. Use WD-40 It Contains A lubricant.
If it's the stock carb, it is a Keihin CV carb. If you've got black smoke coming out of the front cylinder, this means it's running very rich and especially on the front carb. I'd take the carb off and go completely through it cleaning and rebuilding it. I'd also replace the intake seal where the carb plugs into the intake and the intake seals where the intake meets the heads. It sounds like your carb is flooding. Unless you are familiar with these carbs, I'd advise you to take it to an experienced mechanic. These carbs are complicated and not meant for the amateur to be rebuilding them.
if the open hose on each boot is on the air side of the carb..air will be pulled through them all the time bypassing the air filter... if the hoses are on the engine side of the carb and open... the engine won't ever run right unless you plug them...
i would first take the spark plug cap and spark plug out of the cylinder that is missing...place the removed plug into the cap and hold the plug by the cap to a a part of the frame and turn the bike over to see if you have spark at that cylinder.
if you do...go ahead and try some starting fluid spray in the hose on the intake boot.
if you still have problems there are other things to check.
check the air breather make sure it has a good filter if it does it sounds like you need to clean the carbs I would also check for intake leaks by starting the bike and then spray carb cleaner all around the carbs and intake more then likly you have an upstuction in the secondairy jets
hello, you may need to check float in carb, could be sticking or bad, make sure plugs aren wet with gas insted of oil, you can smell gas fouled plugs, than oil, gas coming out of breather sounds like float needs to be adjusted or floats bad or trash in carb, may have broke ring also
