UPDATE - Phelan helped me out with an XB12 TB and rebuilt fuel injectors (thank you Ross), I have the Dean Adams exhaust (thanks Dean), and the XB12 Header, all ceramic coated. Going to mount this stuff up, fire up the laptop, and start playing with fuel/timing.
As for the 1125, I bought - (nay, stole) - a 2008 Aprilia RSV1000R Factory (9,100mi) with Ohlins all around for $5,500 in Phoenix last December. That thing is like an angry rhino...amazing - street legal superbike. It finally shipped, arrives here next week.

OK, so just getting to this now...and no hurry as it's cold as hell here....38 today, should be upper 50s.
In any event, I bought the updated '07 oil pump and the bronze alloy gear. Have to relieve pressure on the rockers to get the cams out....and I'm only 4 bolts each from heads off.
With the XB12 intake and ceramic coated header, am I opening this stock 984 up too much and going to move the power band way up? Should I throw a 1050 kit on it now? Used my Snap-On bore scope and it's clearly a 15k motor....could use a fresh top end....not terrible, but not great. Then, do you send the heads out. Ugh, where does it end? First time 'rotating' the motor, and for the work, seems like I should at least consider it. Looking for some advice...motor seems to run fine now, plugs seem fine. Thoughts? |

Well, there is no end to the rabbit hole unless you create a firm limit for yourself. If there is a place to bore the cylinders nearby, you could price that. Maybe just hone them and put in an oversize set of rings or go to the first overbore size.
Heads could have a lot done to them, but it will cost.
If I was doing it again, I would clean the heads up. Grind dimples in the intake all the way from just before the fuel injector down to the valve seat. Don't forget to dimple the valve guide where it sticks out into the airflow. I would also do the valve lightly, need a diamond cutter for this (Amazon was cheap).
I wouldn't try cutting the port larger, don't completely know what I'm doing and it should match fairly well as is. I would look carefully and make should the ports did mostly match and fix with a minimum of metal removed.
When I did the above on my little race bike, it made a big difference even with the junk clone carb that was still attached. The CNC dimples look great and work great, but sitting for several hours and grinding your own works as well.

Personally I would install what you got and ride this Summer (since Spring is cancelled). Other stuff is fun but a lot of money for little gain. I have to fast stuff I could sell you even at that, if you are insistent, but I think you will greatly enjoy it just with the mods you have now. |

Hmm...the "dimpling".
An idea that has little merit inside an engine intake port.
Been tried by experts, and demystified by the experts.
In drag racing and American engine'd road race engines...been tried and passed by years back. No NASCAR either.
And yea, an 4 stroke engine is a four stroke engine, no matter what it's bolted to.
Save your money/time.
Just "don't" polish the ports past the injector, leave the surface a little rough. Can be polished prior to the injector though.

OK - So it's all back together...got about 100 mi on it in a couple different rides. Followed break-in per NRHS recommendations with the exception of just running the stock 2003 BUECG map....which shows up as a 2004 stock map on/in my RACE ECM. Mods include 1050 kit, ceramic coated XB12 header, Dean Adams exhaust, NRHS Stage 3 cams, heads ported and decked 0.30", bronze oil pump gear and 2007+ pump, and a ported XB12 TB with pattern mapped rebuilt injectors. Need to tune-it now, I bought TunerPro RT looking for advice on a tablet as my old laptop may be part of my problem and certainly won't do data logging. I think I want to keep to a Windows tablet due to TunerPro (household went Apple years ago), and I want to put in the tank bag to do data logging. Feels rich on the bottom, still under 4k RPM, but it pulls/cleans up around 2800. Looking for suggestions/assistance, ideally a tutorial, but take any help I can get. Sadly, I'm an IT guy by trade and am struggling....miss the Keihin/Mukuni days....got really good at that and used to help guys all the time even so far as tweaking needles with a lathe for the track for those that may recall. Feel like an idiot, so any help is appreciated.

Why not use ECM-Spy--I can tell you it is WAY more user friendly |

Well,....I suppose I could buy ECMSpy now too.. |

Hey Skip, I'm no tuning pro, but I'm comfortable with ECMDroid (free) and I got burner with no contract for $39 that was last years Android.
Wireless hook up to the bike (Buelltooth, $45), drop the phone in my pocket, datalog, run it through MLV, bam...
I know it's not the hero way to 'build a tune from scratch' but waaaay easier, hugely faster, and the AFV stays between 99-101 so it's close enough for excellent power and ride-ability.
I did install a WB sensor in the rear, it also has a NB emulator so I can just run the bike CL after instead of swapping out the O2.
If you enjoy custom tuning, go for it I'm curious about the process and may have a 1250 kit in my future!
If you just want to ride your bike I'm happy with my way.

Thanks Shoggin, appreciate the advice. Tablet shipped today, so hopefully I can use that in the shop and for data logging. Good to know on the AFV, didn't know that. Need to dig through the knowledge vault over the weekend and see if I can't glean some additional insights. |

FINALLY broke in with ~800mi. She pulls, but I need to map her now and clean up the bottom. Totally new ground for me, any suggestions are appreciated, or a tuner I could watch/learn from. Will pay, for those wondering/interested. |
