You notice any gains from removing the Balancers...........any quicker reving?
What type of battery you go with and where did you end up putting it...............sorry for all the questions but this is a really great thread..........you should consider doing a write up like Shane did if you have the time documenting and highlighting all the mods.

motor vibrates more, i dont think it revs any faster ...
2 batteries will fit where the stock battery is located, but you need to fab a new battery tray.
I wouldnt do a build thread, I just bolt shit together,,,, I would nto consider myself a bike builder

I should have the bike back for breakin in a week or two. Hey, its killing me too! After that I need to put some miles on it, add a PC ignition module then have a map built on the dyno.
I would have taken pictures but the shop won't let me use flash powder around all the flamables.
Maybe Jim took pictures before it left his shop. I'll post results as soon as they are available.

Sorry guys, I didn't have a chance to take any pics.
Everything works as a system. There's more to this than flow numbers on the flow bench.
The bigger throttle bodies are needed to keep the port taper correct. When you increase the MCSA to xx then the taper (volume) up the port needs to increase at a predetermined rate right to the belmouth. This often means you have to increase the throttle bore size to keep that ratio all the way up. But not always.

The bike lives! Initial dyno numbers look very promising. I need to scrub the motor in and do a final map, should take about a week and a half.

Not at all, just don't want to post erroneous information. The motor is making significantly more power that with a pipe and PCIII.

I don’t remember exact numbers, honest. The dyno was used to heat cycle the engine a couple of time to check for leaks. The engine was only run up to about 5K. Without any fuel map modifications (dyno indicated lean) there was at least 15% increase in HP and the line was climbing very quickly.
Looks like Jim done real good.

This is on stock bore and stroke?

What mods did you do Randle?

The build is a moderate one. +2mm overbore and 14:1 CR. No stroker.
I purchased the bike with zero miles and scrubbed it in. Ran a baseline dyno which yielded 171bhp corrected at the rear, about average for a ZX14.
Added a Brocks Alien head pipe, PCIII and a K&N. I installed a speedo healer, removed the secondaries and fitted an Innovate data logger. A custom map was built for CO numbers only. Same dyno gave 185bhp corrected. There was more hp to be gained on the dyno but my first mile was coming up.
In preparation for the mile I cut the tank for a better tuck. I hot lapped my first mile doing 28 passes in three days. I really needed seat time so did not bother with fuel map or gearing, both of which were WAY off. Best pass of 169mph; consider I was just hitting shift point for 6th when I ran through the traps.
Thoroughly addicted I skipped a few steps and decided to build a solid motor. +2mm over bore, head ported and custom grind cams. Almost as pretty as Jim’s head work a pair of BST wheels will be fitted, now I have a dyno wheel and tire just like my hero Karl!
Once I get the street miles on the motor I will swap to a free flowing air filter and have a base map made for the engine. An ignition module will be added to the PCIII and tuned on the dyno. Initial tuning will be with Sunoco 116 and for CO numbers only. Subsequent runs with be looking for more hp.

Randle,
I recomend dyno tuning on and running VP's MRX-01 for LSR events. Its rated at 98 octane and it should make quite a bit more power than the Sunoco 116. You only need about 100 octane rated fuel for that CR. And its highly oxygenated.
I would tune the A/F ratio about 12.4 on the dyno and then data log at the track. Make fuel adjustments each run and get the real world A/F ratio to about 12.8-13.0 at top speed in 6th.
A good timing map will get the last several HP out of it.
I'll call Andy again today and update him on some other stuff also.
I'm looking forward to seeing what this combo will do.

Thanks Jim, I really appreciate the advice. My plan is to use regular oil on scrub in. I was thinking Motul sythetic or Alisyan zero weight for events. Any thoughts?

Just a thought (as I'm no expert), but I would not run 0w oil in a 14:1 compression engine. That would put a lot of extra stress on the rod bearings. I would personally be a lot more comfy with a heavier weight oil.

Yeah, I am old school. its kills me to put 5wt in my car engine. From what I understand the bearing tolerances are so tight if you use heavier oil it won't lubricate properly.
Maybe I should use Harley brand 90 wt.

That's not what I'm suggesting. A 10w40 might be a better choice though......

The build using Jim’s lovely head ran into trouble. No fault of the head, once the problem was corrected the engine ran fine and is producing impressive numbers. I have yet to fully scuff the motor in so details will follow.
Bottom line. Do not use JE 2mm over size pistons in a ZX14 with Jim’s stage 2 head. You will encounter interference issues with the intake valves and piston valve pockets. JE was made aware of the problem and declined to admit any design flaw or consider changing the design to accommodate larger valves. Make of this what you will.
Engine opened after incident:
A) The pistons are facing the correct way.
B) Head installed on block with Cometic 86mm gasket
C) APE studs, torque head @ 60FT/LBS
D) Confirm valve clearance 0.006 to 0.008 intake. 0.008 to 0.010 EX all OK
E) Install web cams provided. Degree cams at 0.040” checking lift. Intake opens at 16deg BTDC, closes at 46deg ATDC. Exhaust opens 49deg BBDC and closes at 15 ATDC.
F) Bike started and rattled a little. I thought I had the manual tensioner a tad loose. Tightened it and noise simply stopped.
G) Two heat cycles later; on to the Dyne and the bike was run to 3,4,5 thousand RPM at no more than 5% throttle.
H) The bike stalled for some strange reason. Tried to restart. Big pop thru the intake. At which time I decided to take a look inside.
The combustion chamber is full of shavings from the intake valves touching the back side of the valve relief in the piston. It also looks to be at a slight angle.
The valve pocket diameter measures 34.50mm across and the valves are 34.40mm in diameter so there is very little room for error.
In my opinion.
A) Either the pocket is at the incorrect angle.
B) The pocket is too close to the center of the piston.
I think it is (A) because the damage looks to be shaved at an angle.
Pistons after modification:
JE makes good pistons. In my opinion they should have stepped up to the plate on this issue but refused.
