They have two eyes and 10 fingers so they think they need to post 5 times as much as they read. And since they have 10 fingers and one brain, they only have to think 10% of the time! "

I did the air into the exhaust port delete,sprint air filter ,Muzzy pipe.When I got the power commander it was set at Zero.Put it on the bike and went for a rode test.I didn't even get out of the driveway.The bike wouldn't accelerate.Thought maybe the power commander was screwed up put it back to stock.Way worse. I did adjust the valves found them all over the place.Set the intakes to .009 and the exhaust to .025 mm.Cams are timed right because I one 1 tooth off and couldn't turn the only so far one way or the other and it would stop.I got the stuff to adjust the settings in the power commander and starter out looking at other maps for a base line and starter there.Rode the bike still very much more than 5000 rpms and it would lay over.I kept pushing the fuel to it until it stopped making a difference still starts laying over about 5500 and won't pull to 7000.Now 2 falls ago I moved to a different storage rode about 4 miles and started losing power and the bike finally quit.I could hear the fuel pump not priming.So I took it apart on the side of the road and found the metal bowl full of rust.I clean all the rust out and flushed with VP 12.Put it back together and no issues.Bought a new pump and put it in.Didn't check fuel pressure.and I haven't done a plug check.I took the injectors out to see if any of the rust had made into them and didn't see anything.I did find one of the boots for the throttle bodies folded over and I straighten that out but that didn't do anything for it.I just now ordered o-rings for the fuel rail as they leaked when I put it back together ,new injector seals, new mounting boots and new vacuum caps for all the stuff I removed associated w/the air injection.I'm going to put it together,do a plug check before I run it and spray ether to see if I have any vacuum leaks. I'ved tried and tried to get ahold of rivers to see if there a place that can calibrate the injector so there all the same and not just clean them but he has never got back to me.Also this bike has sat 7 years because of a crash.I got all the panels replaced and now want to ride it.There diffidently something screwy because with fuel curve I have in it it's getting about 10 mpg.I tapped the upper port and put a plug in it for the block off for the air injection.'04 636
