the best fix i found was to not ride it under 3000rpm. 3000rpm is very low. I dont think too much time is spent on the fueling of these machines at revs such as these.

I don't think you need to both re-chip and fit PC, either on it's own will do, in fact if your bike is standard I'd just fit a PCIII and get your bike set up on a rolling road with dyno. There is a 'hole' in the power curve on the standard 1000S, a good tuner will put a custom map in the PC for you and sort the hole.

isnt that hole not til about 5k though? i really didnt think that a PC would have much effect under 3k. would like to be proved wrong though as if a PC made that much difference from such low revs id get one fitted.

If I recall correctly it was between 3 and 4000 rpm on mine.

Where are you based ?

I can do a new chip that would be alot better than what you have now including a new ignition curve, modified ebs map and fan control....I have been modifying it and testing it in my 2005 S.

But you need to make sure the base tune is set up propery ie idle CO, throttle balance and TPS is ok. Mind you, you would need to do this anyway.

Cheers
Adam

I simply purchased a MV Corse Race ECU set up for RG3's. It's twice the machine it was before the ECU and the throttle is smooth through out the entire band

Skip the chip, just get a PCIII USB and get the bike to a dyno shop. Also, going from a 39 to a 41 tooth sprocket in the back helps with take off.
