Yea, programmable seems to be the right choise here? A zeel should work with any porting,head,pipe configuration. Still intrested in how the mysteri "Nev" box works tho.. JORGEN! Are you happy with your Ebos heads? Whats the pressure reading vs. stock heads?
I have measured my Ebos heads to 2cc (ml) less than stock heads. Upside-down test using burette and plexiglass, with ign plug.
That equals to about 8% less volume in head.
Made for 195-200 ex duration 1.0 - 1,2mm squish clearance.............I think.
Have anybody here done a cc for H2 heads? Or know the stock cc given from Kawasaki?
Reason for asking is that my volume results differ from others, but the measurement is done on 2 different H2 heads.
I got 26cc, while I have seen 28cc readings from others. Not trapped volume above piston at TDC, but the volume of the head itself with the plug inside, so called "upside-down volume measurement.

Measured my stock heads tonight at 28,5cc vs. 23cc for the 16:1 heads. Installed cc on my 780 cyl. is 25cc that means cr. is 11,4:1 and just 6,2:1 trapped.. That in combination with a huge squish (about 1,7mm.) will defently hurt lowend!
Have the 16:1 heads at a local machine shop and they are not used to this kind of work but will try to help me
Will try to get a pic. up here tomorrow as i/they need some advise how to cut em.. And measure procedure was same as Jorgens only i used a syringe from the local pharmacy, don't know how accurate they are..
