So I finally got my bike rebuilt and broken in. The mods are listed in the signature. I go to school at WyoTech so Im using their dyno. I took it into school last night and got it all inspected and checked the EGA. Its running super rich. Its to be expected for a canned map though. Tomorrow afternoon Ill be spending about 4 hrs on the dyno and getting it dialed in to a ride-able state. The focus will be first getting the WOT tuning perfect. Ill go in on the next shop day and get it fine tuned and fix all the lean/rich spots at various throttle positions.

I did the build at my buddys house in 3 days, tear down and rebuild. I also had a friend who owns a garage blueprint the heads and get them all back to spec. They really werent too bad considering they had 55k miles on them. I was going to weld the crank so I had the cases split. I know I prob wont be putting down the power to NEED the welded crank but I figured it at least a good idea since I could get it done for 50 bucks and Id have the engine torn apart anyways. I got into the case and saw my crank bearings were Timken. So after talking to my instructors and a few other HD gurus they said just leave it since the 02 crank was one of the better stock cranks HD put out.

I am really excited as well to see how the PV-1/WinPV does with dyno tuning. I always hear a lot about the SERT and PCIII/V but I dont know many people who use the PV-1 or 2. My instructor has never dyno'd one either so hes really jazzed about it.

I spent way too much money but Im super excited to see the numbers and feel the PROPER performance from getting it tuned properly. Im just hoping for 90 hp/90 tq. If I get that Ill be happy. Updates will come tomorrow evening and hopefully some dyno sheets or screenshots of the computer.

So I go to the dyno at school and one of the instructors jumped ahead of me and threw his friends bike on the dyno for a quick diagnostic run. It wasnt running properly. The engine had an estimated $12k into it. SE heads, 11.5:1 domed pistons, 95 ci, 510 lift gear cams, PCV/Autotune/Wide O2 and a host of other stuff. It also had to run on race gas. He did two pulls and made 82hp/92tq. The problem was the improper grouping of parts and a horrible tune. I laughed at the weak numbers. The dude apparently brought a sheet in from the builder saying he should be making a corrected hp of around 120.

I say all that cause I did 7 pulls and my best was 82hp/90tq. My $3k worth of parts and dirty, daily driven RG made the same power. Again, I laughed.

The tuner Im using is the PV1. I bought it thinking it had the same capabilities as the PC3/PCV. It to a degree does. We started making a few pulls and tweaking the A/F ratios. Flash the ECM and repeat. We werent able to change the the ratios past 13.2. The bike was getting hotter and was leaning out even more because of it. We couldnt get any good results.

I called dynojet, who by the way have been pretty great with their tech support, and my instructor talked with them. He was informed to manually tune the map the values on the A/F table and the VE table must be the same for each KPa/RPM block in each map. This would take hours and hours. So we didnt get anywhere.

It was designed I learned to work specifically with the autotune and wide O2. Wish I wouldve known that lol. So I just picked up a PC3 and Im gonna use that. Next week hopefully Ill get it back on the dyno with some solid numbers. I was pleased with the numbers I put up though considering how bad the basic tune I had was.

Check out the HORRIBLE A/F ratios on the bottom graph.
