Trying to sort the fueling on 2015 660R
 

Hi all,
I�ve had the bike for a couple of months now and from day one I�ve not been happy with the fueling/surging problem.
I�ve read the forum till my eyes are sore and with so many people saying conflicting things regarding settings for Co etc. I�ve decided to ask.
My bike is a 2015 with the O2 sensor, am I wasting my time changing the Co and TPS settings? Currently got them on Co - 22, TPS - 17 and still getting annoyed with it surging. Tried the Co at 18 and it cut out changing down into a roundabout.
I�m running stock pipes and filter.
Am I wasting my time? Would a PCv be a waste of money with standard pipes?
I may go 2 Into 1 in the future.

Regards- Jim

Have you thought of 'Kev's' mods?...

Yes, Kevs mods are of interest, but I�m not sure if they are suitable for my bike. The only info I can find is on the earlier bikes. I�d like to find out exactly how it would work on mine and what the effects are. I�d really like to hear from someone that has a later model like mine, that has done the mods.

Cheers
Jim

Mines a 2009 and tbh I wasnt aware that it differed to yours. The mods are not performance mods but they ARE effective at making the bike run as it should have done when it came out of the factory.

Both my bike and my Bro's bike run sweet ..

Performance wise DNA air filters flow air better..Stage 1 replaces the original air filter,stage 2 replaces the side of the airbox with an air filter.
