As of now John is hard at work and I copied and pasted what he wrote in the other thread here for the update. AMR 800, XX cams, Muzzy Pro, Power Commander PCIII, VFORCEJOHN Stage 3 spidermod clutch with Maroon Spring, EHS air box lid, and a bunch of little stuff John did to make it run better...
Thank you Glenn at AMR and John at Interstate Motorsports. John has gone above and beyond for this build!!!...still going. with the EHS lid, injector duty is 90%. I have larger injectors. (thank god I don't have to order them :lol when things cool down, I'll swap them. it's a good hour job.
so far it still stumbles out of the hole a/f is dead on perfect. something in the ECM is cutting back timing or something. I tried the vacuum canister on the map sensor. it helped low end a little but not a direct fix. I tried crossing the intakes. mini ms mod on the vacuum nipples under the intake flange. that did nothing. I also crossed the larger IAC sensor lines. that helped a little but still not enough to be consistant. That is this things main problem. getting a consistant run and keeping it there
I have 4 kawy map sensors, they all do the same thing. so it's nothing faulty. funny thing is, I can sit the map sensor on my lap with a longer vacuum signal hose to the head. blow in the sensor with just breath (like you are blowing out a candle) and it'll run better. a/f changes richer, but from 12.5-12.6 to 12.1-12.3 I can up the a/f with the pc3 to 12.1-12.3 and it runs worse. seems to like 12.5-12.8 range for max power.
Ignition module is on and timing is +10. maxxed out. past 7000 rpm I dial it back to 8 and then 6. runs the best like that.
pc3 fuel pump enrichener is on actually I dial back the fuel not enrichen it and power came up low end. so that's done
FI on these BBK bikes is a waste. if this thing was carbed. it'd be 68-70 rwhp easily. that motor is strong as hell.
If you roll on it at 20, power is 62 rwhp @ about 50 mph and keeps climbing . gun it out of the hole and something restricts it. You can immediatly hear it/feel it something happens, it only makes 57-59 rwhp and falls flat on mid-top.
with out the pc3. 42 rwhp. it won't even run just stumbles, but still blows 14.5 a/f
back to tinkering. it should be cool enough now to put the injectors in. I'm also going to flow skips stock injectors. I'd bet the rear injector flows less than the front. exhaust temps are near 80-100 degres higher. front runs 675 rear is 750-775 could be related to the bends of the muzzy pro. upping the cylinder split feature 5% will make them very close in temps.
and The new rings Glenn sent me are about the best I've ever had in one of these motors. there is ZERO blow by even holding it at 80 mph. not even so much as a puff of air or oil.
the 1 layer head gaskets are holding nicely, no issues there either.
back to work
