I'm closing in on the F4 R. Its probably going to reside in my garage...

What are the obvious mods? It will be a street bike.

I do not want any issues with longevity, or warranty.

pipes? ecus? custom mapping? etc..

I think I read that you can not piggy back the power commander. Is this true? Is the stock ECU programmable?

What about taming the abrupt throttle response mentioned in the magazine articles?

Hey No Quater,

When I get my F4 R I plan on getting the RG3 exhaust for the bike which comes with a new ECU and the stainless mid pipe. Of course, I like to stick with stock mods. This should give me way more power than I will ever need.

Cheers,

i don't believe the new ECU takes eprom chips. the RG3's w/eprom would apply to the S models. the slip ons are the same as well as the mid pipe, but the header is different between the two. if you do get a true R/Senna full system, all you will need is a PCIII and a new map.

unless someone can chime in differently....

Well, it sound like the RG3 and PCIII are the best upgrades for the S. Sound like it puts a stock S close to an stock R - maybe even a bit smoother?

I've been out of the loop. How much is the RG3 full system (not the Ti version)?

PCIII is possible, makes it for owners possible to tinker. As the software is free.
Else dongle software is needed to modify internal settings! same applies for rapidbike software
PC3 is possible hb but you need a "Fix" from Dynojet (or me!) to make it read 100% revs instead of 50% revs
PC3 DOES NOT get rid of the hideous emission related flat spot at 4000-5000rpm, RG3 ecu might but i'm not buying one untill I know for certain.

The std ecu fuels relatively OK even with RG3 but the 4000-5000rpm dip is real shit and I mean this seriously, it only happens on very small throttle openings, 2%, 5%, and 10% according to the PC software, I see Ferracci is re-programming ecu's as well,

In the wet the thing is dam right dangerous, your just crawling out of a roundabout at 4000ish then wham! the f*****g thing takes off, It feels more like an early 500 triple Kawasaki power band than a state of the art 1000cc four stroke, :jsm:

I'm not sure why one would need to modify this bike too much, other than dyno tuning from what I read so far.

I would put good rearsets on it, make sure it's sprung for you, MAYBE put in a freer flowing air filter and pipe, and get it tuned.

What Mike says above can only get worse if the bike is modded without proper tuning.
