Just a thought as you asked...sounds like a poor throttle position potentiometer ... throttle cabled to butterfly most likely and if ECU dosen't know throttle plate moved you will see this symptom . If electric throttle , can you see(hear) plate moving whilst twisting , if so measure resistance/voltage on pot. . I do not know if resistance of position sensor can be measured while twisting throttle or pushing plate (bike off , battery disconnected or ignition off)

If old gas sat in the carb. for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this. Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb. Take the fuel line loose from the fuel tank and force it into the carb(s). Let that set for say 1 or 2 days. then hook up the fueltank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb. and remove the blows to clean the inside, I know you said you have already done this but you may have to do it again, and pay attention to very small holes in the up tube . If you have to do that do not DO NOT MESS with any adjustment screws. Just take the carb. bowl off. Do not mix up any internal parts. It is best to work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Hope this Helps Fix Ya Up..

but never been fuurther than a tappet in the engine.If you are not using oil and the smoke only lasts for 10 seconds or so and you get no more smoke later, then I would ignore it. If the guides were worn, you would also be getting smoke on the overrun. Are the plugs getting fouled up? Again if not, ignore. If it aint really broke, don't pay out wads to fix it. (Unless you are a perfectionist, and insist on everything being perfect regardless of cost). Even if the guides are a little worn, and it will only be a little at this point, they will go on for some time yet.,,,

It seems that the fuel is not reaching the carb in the right quantity, that is why it runs while idling and sputters when you need more fuel after a few miles. Get the fuel line cleaned and also the carb and ensure that the fuel is flowing freely. Or if there is a fuel filter then that needs a change.

what is the original problem that makes you think it is cam shaft problem
If the manufacturer used cheap cams (not likely as it affects the brand name) the engine is under warranty and the cams would be replaced by the company
Find a different service center or contact the manufacturer direct to see if there is a recall out on the engine
consider this --if it is a moto guzzi mechanic that was telling you this , then why was it not booked in for replacement parts under warranty
I suspect that he was trying to get extra money out of you and was not qualified in the product

Bad connection or faulty starter. Check voltage/current to the starter when you press start - should be around 8/9 volts for a 12 volt system - if considerably higher suspect starter, if lower and little current flowing suspect poor connection somewhere. If the voltage is low and current high suspect starter.

Probably have to remove the seat first. Most fuel tanks are retained by u shaped flanges that grip a round rubber puck on both sides of the frame near the steering head. After you drain the fuel, lift the rear of the tank slightly and pull it to the rear, it should then be free to lift off the frame.
