Sounds and looks good. Is max boost during run 1 Bar or 10 PSI? it is difficult to see on the video. I guess it is 10 PSI. Clean gauge setup :icon_cool:

Is the AFR meter out for lunch :icon_think:

Yeah the af meter needs to be sent back. It was at 10lbs boost.

And a little math for you.. 135 hp * (1+(10/14.6)) = 227 - 5% = 216

If you want more power you add more boost - 95% efficient is quite good for a street system.

She sounds healthy too.

Thanks man! Here is the graph.

There is some more power to be had there -- AFR should be above 11.5:1 on boost and it looks like it dips down to 10?

Hank?

Agree, there is no reason to go below 11 to 1, even though a dip into 10's is OK for short load situations.

It seems to run extremely rich at light loads, below 10 to 1 in case the AFR curve is valid also in the low speed segment. :icon_think:

Jim (the dyno guy) had said he thought #2 cylinder was leaning out due to an exhaust leak. I have fixed the leak. The add on pitot tube assy has a fitting for different air bleed jets. He told me to put in a 230 jet in the hole. It is now plugged. He said that would straighten out the af ratio at midrange rpm. I didn't want to put it in yet as it seems the bike runs quite warm as it is. It overheated once already on my ride last Sunday and that's with the fan switch bypassed to a manual switch I installed. I'll mess with it a little more but this thing does run good and I don't want to ruin it you know?

I understand but extensive running @ AFR 10:1 will foul plugs, wash cylinder walls and contaminate the oil. I would really double-check AFR, especially if the bike was tuned with an exhaust leak.

Again, intermittent loads @ 10:1 is OK but not desirable, extensive running at this AFR will cause problems.

Let's see what Hank will say, he has for sure more experience in this than me.

Jerry, get the Innovate A-F gauge repaired, warranteed, whatever it takes and go from there.

My guess is the factory harness but check the Innovate site for the forum covering that unit.

I agree with everyone else... 10/1 is unnecessairily rich but without having an A-F gauge you can count on, you're shooting in the dark...

As far as A-F under full boost on the main jet, I like to see 11.5.

That provides a margain of safety if the temps drop unexpectedly or if boost rises just a bit.

The other option is a call to Jim and a ride to Batavia...now that the exhaust leak is fixed.

I agree, I meant 11:1 above and 11.5:1 is ideal with an I/C.

Any timing pulled, if so, how much? What octane fuel?

No timing retard...

Fuel octane 93...Hi test pump gas.
