If I can do it, you can do it...I know all you guys are saying that this is an easy mod but is it something that can be easily screwed up if done incorrectly?

Those base numbers don't mean a thing. There are manufacturing variants in everything. Where those numbers are just reflect the differences in fuel injectors, fuel pressure, phases of the moon or whatever other variable can effect the process of mixing gas with air. Those numbers can be from -100 to +100. It just shows how close all the tolerances are that most bikes have adjustment numbers between -20 and +20. What your concerned with is how many numbers you increase it by.I just finished the mod myself. I increased the settings on all four cylinders by 7 increments and then went for a ride.
Nice!!! Now I like the bike even more. I get less mirror vibration, engine is smoother overall and throttle is not as jerky at low RPMs and the engine feels like it has just a tad more low end torque. Any vibration I used to feel at 75-80mph is now totally gone, and the temp indicator dropped by one bar. This looks to me like a great modification. :yahoo:
For the record, my initial settings on my four cylinders were:
1. -10
2. 8
3. 8
4. 11
I would be curious to know how this compares to what others have measured. No 1 cylinder sure looks to be set a lot leaner than the rest.
Even though these are allegedly different for each bike, my settings were exactly the same as Freds'. Maybe excellent quality control on Yamahas part, or maybe they are all just set to the same default values.I just finished the mod myself.

Alberto has prevented riding since doing the mod yesterday. Also did the throttle spring mod. Evaluation to follow.
You are actually making it richer. I have done 3 tankfuls after the mod and my fuel economy went up 2 MPG.Key piece of data missing is how much (or if) this effects your fuel economy. How do you know you're not ruining the mixture (going too lean for example)?

Odd, mine is still the same - 17 MPG!You are actually making it richer. I have done 3 tankfuls after the mod and my fuel economy went up 2 MPG.Key piece of data missing is how much (or if) this effects your fuel economy. How do you know you're not ruining the mixture (going too lean for example)?
Keep it! :lol:My factory settings were initially set the same as v65's:
My original settings were the same as yours, Fred.I just finished the mod myself. I increased the settings on all four cylinders by 7 increments and then went for a ride.
