Course,you say he added 40% more fuel.Could that cause predet?Maybe past the ECU parameters?Knocking wouldn't be good for those plugs?
I've done a lot of work with Q16 and it usually doesn't require 15% more fuel if your map was spot on prior to tuning.

As far as creating an overly lean condition...... if his tuner just dropped oxygenated race fuel in the gas tank and didn't preemptively add 10% more fuel everywhere in the map to establish the baseline, then he should find a new tuner.

To add fuel to the fire there's' a Facebook thread going on where the CMP guys encountered a kinked fuel line in a customer's bike.

That will definitely cause the problem described in this thread.

My dyno guy asked me not to post the dyno because things quickly get misinterpreted on the internet and he did not want to get a bad rap for something that was outside of his control!

I don't blame him!
Block out the name of the company on the graph, that's not hard to do

'Here is your evidence'..looks fried to me,not broken.Can't believe however this is a 'common' issue with a motor designed to run plugs to 30K miles before replacement.I do think that particular motor was flogged fairly good.Something.That's not normal operation doing that.Unless of course,that one plug was somehow faulty.That could happen.
Were you referring to those that are hammering their bikes or something?Or modding em to get H2R HP numbers?I may be not understanding your post then?

I am again still waiting for you to say why you think the fuel pump is culprit! You post no graph, you have not said what the AFR was. All you said was you tried adding 40% fuel! Does that mean the bike was running lean? If so by how much. This is why people ask for the graph.

You made within 2whp of pump, but did you gain midrange? Again that's why I want to see the graph. Q16 isnt the be all end all fuel for the H2. It makes good mid range, but not much up top. Guys have tested this fuel and shows it plateau in the upper rpm. They have also tested it in mph and noticed no change or a loss.

Its not a common occurrence. The only common occurrence is people melting them from over abuse and running the bike too hot.

My own personally experiences with a couple different oxygenated fuels was about 5-8% variance from pump gas. About half a point in AFR difference. If you were running 12.0 AFR before the bike should have still been well within the safe limits even with no adjustments. I would also look into injector split adjustments too as mentioned before.

What was the date of the Q16 on the can?

Here is your evidence.

Oh thats been lean alright,not broken, the electrode burnt off dont see that too often without other damage

When you run out of enough fuel with forced induction, there quite happy to burn aluminium or steel

My experience with Q16 was 8% fuel addition which netted a gain of 10hp everywhere up to 12k rpm and then it backed down to 4hp gain from 12k to 13.5k redline.
