hi do you mean the injectors themselves?

If so this thread is very useful [You must be registered and logged in to see this link.]

I've since discovered that the 190 has ~10% higher flow rate than the 189.

That is interesting as [in theory] if you thow 10% more fuel into the pot for each pulse you should get 10% more fuel consumption and those hydrocarbons could [in theory] produce 10% more bang Exclamation

I never read of a 10% power increase and I wasn't aware that the later ones are more thirsty Question

Q is though will the 190s affect the running of the bike, ie flooding at tickler,bogging down on throttle operation?

I don't know why I mentioned it. I plead temporary insanity. I apologise for my nerdy pedantry.

Taking into account spray patterns and fuel pressure, the end result makes diddly-squat difference. The 190 was used in 2010 & later models. '08 & '09 models would have run a bee's dick less rich than later models once updated to the 2230G803 or 68S maps, but we're talking micrograms of fuel in a relatively thirsty environment above 4500 RPM.

If you run one of my maps, they were all made with 190's.

I go now.

Are they the same as 1100 ones I have a new one spare

No, the 1100 uses IWP162

This is the holes pattern
