Exactly. And it's not that people are not capable of servicing every area of the bike, but carbs can get messed up easily. Heck, Steve will do a set of carbs perfect, and then the end user will run old rusty gas through them! I almost hosed my SISF carbs with a leftover fuel line, I am good at being a dumb smart person.

I also hydrolocked my first Concours, but it may have not been the first time for that bike, which had a really sketchy history. I was sad that I had to find a replacement, but I ended up with a much nicer bike which I love.

Finding a replacement engine through COG was incredibly easy, and the engine ended up coming with the bike for the same $400. COG member Eddie in PA was incredibly helpful and overall the experience was positive.

Carb rebuild kit, valve adjustment kit,sparkplug wire and boot kit.

Just maintenance stuff while I have the bike apart to inspect and fix other issues. Lol.

This cam cover is a pain in the rear.
Have all the plastics removed, the crankcase vents, the hoseclamp  moved outta the way, the fairing frame moved, yet I STILL don't seem to have enough clearance to remove the cover... Grrrr

Cancel that. Removed the gasket that was still on the cover, left it on the head. Cover slid right on out.

Well, I wanted the cover off to at least be 100% sure whether it was in fact bent, you reply came just as I posted, but yeah, it's bent the 2mm I estimated from the quick test while the cover was on.
I'm curious if it was bent prior to me owning it, I can tell it's been taken apart before, so, maybe one of the previous owners sold it with the issue.. Idk.
All the fasteners to get to the cover, including the cover, has been messed with prior.

maybe maybe not. it could have been opened up for regular maint. such as valve adj. but you know you did lock it yourself once.

so as the old saying goes "if you smelled it, you dealt it"

Well, so far the first two intake valves, 1 and 4 are contacting... Zero clearance cold..
I doubt it was opened up for that at least.

33,000 ish.
Also as an update, the carbs have been messed with previously, they are quite clean and you can tell someone has removed the jets before as well.
Diaphragms are pinhole free.
I wonder if someone took apart the carbs to solve the back firing problem from the valves.....

What you've confirmed is that someone messed with the carbs and failed in their attempt to clean them. They are not clean. If they were truly clean you'd never have hydro-locked. More than likely that they messed with the carbs because they had experienced a hydro-lock situation of their own.

I kind of agree about properly serviced carbs.
A perfect set of brand new carbs can still fail due to a tiny piece of trash or dirt getting on the seat or tip of the valve. I have had it happen.
A little spirited  driving (short burst of WOT) usually clears the trash  plus there are a few other tricks to clear trash  ( beating on the carb with a heavy object is NOT one of them)
This is why it so very very important to have overflow tubes installed. No other device can tell you that have a problem before you have a bigger problem

Normally aspirated engines have perpetual turbo lag

Well, I have returned! Thread revival!!

The bike was taken apart and basically mothballed because of life getting in the way.

This time, before I take it out for a ride, I'm rebuilding any subsystem that can possibly give me a problem.

So far my progress has been cleaning the whole carb, replacing the float valves, pilot o-rings and reinstalling them onto the bike.(without the fuel bowl modification because I'm stupid)

I'm going to have to buy another front master cylinder and rebuild it since the screws snapped off in the reservoir.
Then I know I have to replace the fork seals since they are pissing fluid everywhere.
I'm also going to replace or rebuilt the petcock, add a fuel filter, and possibly a backup valve just as a precaution. (since I'm too stupid to get the bowls modified.)
I forgot how much a pain it was to get the carb rack in and out of this bike, holy moses.

Going to flush out all brake fluid, and change all oils and drive oil..

When bike is fired up again, I'll be syncing the carbs with my carbtune.

Am I missing anything? ;)

I found it hard to find an inline filter that fits in the small space between the petcock and carbs under the gas tank. Emgo brand makes one with glass so you can see when it's dirty. Some people here use NAPA Gold 3006. It flows well, but it's big and made of plastic. Good luck.

Oh yeah, hope you cleaned the pilot jets really good if it's been parked for a year. Mine sat for 6 months and had gummed up the pilot jets.

The carbs were already completely taken apart and partially cleaned before it sat for a year so I really didn't have much work to do to them

Ok, so no gasoline was left in the carbs? That's good. Hydrolock takes two failures, the carbs (usually a needle valve that won't close all the way) and a bad petcock. So, you're already dealing with the carbs, check. I would replace the petcock with a Kawasaki brand part rather than try to repair the old one. This is one time that maybe you shouldn't go the cheap route. While I don't have personal experience, I've seen on the forum that a few people had additional problems after rebuilding the petcock. Hang in there, we're all pulling for you.

Welcome back. So the bike is runnable on the current bent rod? Does anyone know what the tolerances are for the rods?

I guess I'll find that out in a bit. It had quite the vibration before the lock happened, so it could always be prior to my ownership

Mine was bent about the same as yours. Ran fine. Only thing I noticed was reduced power.
Installed another motor and planned to replace the rod. {And make it a 1052}
Bought the parts, but still haven't done that as the other motor is still running fine.

Ride safe, Ted
