Re: f4i engine rebuild...seized AGAIN?!
yes, get rid of the fuel injection and bolt some carbs on the bike 
Can't just bypass the ECU, the reason there is a ECU is because the bike is fuel injected, and it since it has a ecu im sure the ecu also controls the ignition timing, and I'm sure it controls more

Re: f4i engine rebuild...seized AGAIN?!
FUUUUUUUUUUUUUUUUUCK!!! 
it blew AGAIN!
1. put the new head gasket in
2. finally put her back together (after fixing a buncha FI codes except #23)
3. sounds fine
4. as soon as i exit driveway, sounds like it's running on 2-3 cylinders
5. ride it a 100ft, i look back and a ton of smoke is shooting out the exhaust.
6. i though w/e, it's from the airbox or sum ****, but the smoking did not stop.
7. another 100ft back to the house...5 feet from my driveway, i hear what sounded like a chain falling off a sprocket, so i turn her off and push it the other 5ft.
8. tried to fire her up, SEIZED!!!!!
i'm FUCKED...right? woohoo!

Re: f4i engine rebuild...seized AGAIN?!
jesus ******* christ I DID IT!!
YYEAAAAAAAAAAAAAAAA!!!!
my homy sal came over, big dude weighing in @ 350lbs.
he asked if i had a long breaker bar, 4-foot 1/4" thick pole.
with the bike on the 12 bar, put that pipe around a half inch driver, on the clutch lock-nut, once twist, and walla, PISTONS ******* MOVED!
he went for a 2nd spin and broke by outter clutch cause i had vice grips connected to it...which i had an extra one.
read to break it in.
anyway, put everything back together, fired it up, let it warm up to 120, and took it for a spin, i rode it for 100feet, if don't give it gas, it does, and the whole time it runs/sounds like its running on 3 cyclinders.
my guess...i didn't install a new head gasket, so i got that on the way.
any other ideas before i put this bitch back together...again

if it took that much force to turn the motor over you clearly had an obstruction , had you taken it apart to see what it was you probably would have a running motor right now but instead you fucked your **** up ...

Re: f4i engine rebuild...seized AGAIN?!
lol ^^ true dat...f4is, i get along with, their motors, not so much...if i didn't have so much custom parts and a clean frame on this bike, I would light the cursed son of a bitch on fire and post the video on here.
thanks for the support jackass
p.s. the motor was spinning freely/normal after i broke it loose with the breaker bar.
whats tripping me out is where the **** the oil/smoke was coming from...blown rings? but why how?!

i was just surprised to see you didnt check to see why the motor wouldnt turn over ...as far as the smoke goes you may have cracked a piston or some thing while forcing it to turn over

**** you could have even cracked a cylinder by using a breaker bar to turn it over if there was a nut or a bolt dropped in the motor
