I am getting a mint preowned stock F4 1000S in the am one that has only 400 miles on it and was able to pick it up for 14K(I think a decent deal). I am just wondering are the RG3 that much louder and what kind of umpfff it will add. Do I need to put air filter in and what other musts are there that I need to know about. Do I need more teeth on the back or less on the front. I am looking to use on the twisty roads only.
That said, the RG3's (I don't have them, though my pipes are cored) will give you a nicer throatier tone (louder but not too loud), a small increase in hp and will improve mid range power a little.
At some stage you may want to change the rearsets as they can become a little slippery once worn.
These bikes are geared high so you could go up in the rear sprocket

-1 on the front gives:

-1 on the front is ok for 600cc or 750cc
I tested both configurations on my 998S. Std is 15/36. I was running 14/36 and I went to 15/39. Much better that 14/36. You feel more torque with a stronger acceleration and no problems with the chain.
Soon I will test on my F4 1000 15/41 and let you know how is it.
Check the link below. I is in German but it can help you to choose your gearing.
Are stock pipes loud enough and how much more would the MV rg3 be? Are they worth a $1900 upgrade with chip and slipons with labor. I am not looking for any more HP maybe a little sound. I was reading that they really aren't to much different then the stock ones.
brake pads for me, moto corse exhaust(beautiful pipe but not required), alcantara seat( again not required), carbon parts if you wanna drop a little weight( its minimal but looks good), so yeah brake pads are what I thought was needed.
14k $??? Yikes, did you have the put em up and hold and up.. and no one gets hurt? Good going! I have RG3 and eprom and a few carbon parts but is great stock.. then again for that price you could spend a little on it and still have, "The Deal"
my suggestion would be to ride the bike for a month at least stock. then you will figure out the MUST DO's for you. after that, question or read the forums and you will know what to do next. modding a bike before even having it in hand seems a little counter-intuitive to me. well except replacing cheap plastic with carbon.
I think everyone who has replied so far has given sound advice. I would certainly ride the bike unmodified for a while before contemplating any changes. If you read through the threads here there are loads of mods you can make. Some expensive and some less so. Aftermarket pipes are very popular on MV's but quite expensive. Air filters, Power Commanders you name it MV's are no different to any other make of motorcycle these days, there are tons of parts available, including my own Achillies heel, Carbon Fibre parts galore. Have fun with your new toy before giving your wallet another hammering.

If you can't fix it with a hammer you've got an electrical problem!
My advise is don't do any mod that can't be simply undone! Beauty is it the eye and all that, but there are some terrible modifications that should never have 'graced' an MV, if its permenant and you want to sell/trade = problem! have fun!
