Well, I think that by now, two years later, he probably knows if the engine is fine or not.

dude its fine, ive personally seen a AP2 rev out to 12K under light load. It's the bottom end u worry about you won't get valve float till around 12kish after that the valve could hit hte piston and BOOM, u'd know if u had a prob here, u'd bend the valve when the piston smacked it and your power would go to shit and it'd sound ilke shit too no worries man, ur bottom end will be fine it was under no load, drivetrain and clutch took the hit . they'll be fine
What part of Billman's cracked retainer threads haven't you read yet?

I give you for being retarded and still having enough guts to post that.

Not only are you two years late, you're info couldn't be more wrong.

Broken retainers show NO SYMPTOMS at all. Not even the slightest noise.

Till the valves drop into the cylinder. THEN you'll know

....oh yaaaa that DATE parts


true story, had my race bike lended out to a friend on S.I.R. and he did a nasty over-rev and oops and they dropped in BOOM end of story.... wait no story gets worse... he didn't exactly follow through on the fix it job and were not good friends anymore.

However! this wasn't overlookd on my part, according to honda testers who i directly spoke with... not through a friend through a friend, the top end will take a SEVERE! beating and the springs and retainers shouldn't crack before the valves just simply float especially with low milage newer car that isn't USUALLY spun past its proper rpm range, my experience is only having cracked retainers when the motor is consistantly pushed or just very high milage, a quick no load over-rev hasn't ever cause ME damage prior and ive seen some WAY high over revs that were scary. I'm sure its all in the motor and condition . Oh and for the bad sound i meant a valve thats been a little tweaked and the backcut is no longer matchin up nicely so you here that spitting sound.
Maybe others have had other experience but thats what the honda testers said. .... and i coudln't believe how many motors honda BLOWS up just for "testing"!!!!!!! but apparently float is the first issue????

have people on here witnessed them cracking and droppin the valves in? god that'd be scary!


On that note,

How well balanced is the bottom end of the 2.2L motor from the factory, that was the first of concerns we should have -straight from honda
