hey guys im in need of help...got a 05 cbr 600rr...got into an accident (some newbie driver cut me off!) where i did a stoppie and fell forward and crashed the front side of my bike!. took it the shop and said that it is on hdyrolock...

i pulled the plugs and made it spit but it is still not working!!! i charged the battery because i thought that the battery was weak because when it was making a clicking sound when i tried to start it.but its still not working....can anyone give me some pointers or know how to fix this...

really appreciate any inputs!!! thanks in advance......

If your engine is hydrolocked there is a good chance that piston rods could be bent, or that one of the pistons actually got messed up in the process. If the shop said this, it may be true. Unless you can take your engine apart at home, the shop might need to take care of this one. And that would suck because it's a pretty big fix.

Hopefully someone here disagrees with me and has an easier (less $$$) fix...

I'm guessing the cylinders filled with oil to hydrolock the motor. I doubt it bent rods... those things are very solid to handle 15k RPM. Your starter motor doesn't have enough power to bend one of those either.

We need more info to really be able to help you out.

^^ You would be surprised how much torque those starters have and how weak rods are.
They are meant to compress air, not fluids.
I fail to see how a wreck Hydro locked an engine any way, did it lay on its side for days?

hydrolock can occur from either oil or water so there didn't really have to be water involved.

the easiest way to hydro lock a motor is too overfill the oil, it pushed up past the oil control rings on the pistons into the cylinder

I don't think you can put enough oil in to hydro lock the motor. I think the pistons are above the oil fill cap so even filling to the very top... you can't get the oil level high enough to touch the pistons. much less push past them.

I mean to lock a motor... you have to get several ounces of fluid in the cylinder. It would take a lot of pressure or a lot of time to get that much past the rings on the piston.

the onlw way I see this happening is laying a bike on it's side for weeks maybe even more to get it to hydro lock.

If he layed it over, some might have gotten into the airbox and into the cyclinders that way. It wouldn't be too much though.

If there is a lot of oil in a cylinder either it got by the rings somehow, would have to be on it's side a long time like you said, or he could have cracked the head in the crash.

i have seen cars clear a hydrolock by pulling the plugs and spinning the starter.
will a bike starter have enough torque to do it

Sometimes you can clear a hydrolock by pulling the plugs, but often when the fluid gets in there it will be a cooler temperature and this causes worse problems.

When this happens, the piston cylinder will be unaffected, it's solid and heavy and retains most of it's heat. But the piston sleeve is thinner and cools down faster than the piston. This shrinks the sleeve slightly, and in some cases it becomes too tight for the piston to slide up and down in anymore. This will cause tons of binding at 5k-14k rpms. Next the piston and sleeve start mashing until the engine is seized up (usually only takes a fraction of a second). And then you're screwed and no amount of torque could turn that over.
