Had the Beast for over a month now I am developing my confidence. I have been nailing the throttle in first and second and the engine feels like its stuttering for a few seconds before it seems to catch and the power kicks in.
Anyone else had a similar problem?
Any ideas?

Hi,

I'm no expert but new plugs is always a good place to start. Check HT lead connections and condition, air filter too.

Then there is the CO2 setting but I've never felt the need to do that but some one else can point you to a link I'm sure.

What revs are you doing when you give it a handfull?

as well as plugs, suggest you look at airfilter

also, has the air box been opened up?

they arn,t the smoothest bikes low down in the rev range.

Stick a set of Iridium plugs in it! Sounds like it could be the plugs to me, maybe just cleaning themselves off as you give it the berries.

Those Iridiums are the business , first thing I fitted to the Tuono. Excellent for starting,and last a very very long time. Just remember not to try and re-gap them in the future.....because you can't

Also, make sure you clean the front cylinder plug recess with a high pressure air line before removing the plug as they fill up with crud which then drops into the cylinder head when you remove the plug. The rear cyclinder should be fine though

I had a stuttering / cutting out problem on my Falco when I first got it. Turned out to be because it was left standing too long in the showroom and developed some crud / bad fuel in the tank which also partially blocked the fuel filter. After the dealer replaced the fuel and the fuel filter it was as good as gold

Thanks for this, its not a big problem as its only when I nail the exhaust, I am off on holiday soon so when I get back I think I'll try the new fancy plugs and a K & N air filter and see if my falco has had the airbox modification

Check out the front plug Ed falco as this plug is often left because its difficult to get at by dealers service mechanics.
You don't say but is the bike running with aftermarket cans or chip? it could mean it needs setting up. If its standard I would check the cylinder synchronization next the air screws could be in need of a fiddle to get the low speed running correct. Its also a good idea to clean around the fuel/air flaps in the air intakes, any build up of oil or carbon around this area can cause a stutter at low rpm.
