Shrimp's '72 CL 350 build

Good idea!!
Pic below from an eBay ad for a lower case. Note the drain plug slightly behind the windage tray location, so if it did fall under the back edge of the tray it might be reachable with a magnet through the drain plug. I've never had one out of the lower case so I can't say what ribs might be under it that could prevent you reaching it from the drain plug if in the forward area.

Ok, have fished around for about 2 hours total with no luck. I've gone in from the top and through the drain plug hole. I may try flushing with diesel fuel as a last chance before splitting the case.

Here's a question: I'm assuming that the engine needs to be rotated upside down before splitting the case completely? Seems the transmission gears would drop out otherwise. Am I correct?

Yes, flip the engine over so it's sitting on the cylinder studs and the upper rear of the crankcase, then (with all crankcase bolts removed both top and bottom) lift off the lower case. It does require both crankcase covers to be removed (alternator and clutch) as well as the complete clutch and oil pump, as well as the shift shaft removed before removing the lower case. Once all bolts are removed, tap the motor mount areas gently with a hammer until you hear a hollow sound of the lower case coming loose, then lift it off.
 
I've been up close and personal with this engine trying to get the roller guide out...and then also working on side cover screws that a previous owner stripped out. I am trying to make friends with this engine!

I did already order and receive the Allen head bolt kit for side covers and top end from those guys in Houston.

I am not familiar with those guys in Houston parts and their bolts kits per se. Many are a SS material and you need to use an anti seize compound on them, or really any JIS screw when replacing them. One of the biggest issues on the original JIS screws is a PO didn't use a correct JIS bit with a proper impact driver to remove them. The old screws and bolts tend to have years of galvanic corrosion on the threads and shafts helping them hang on tight in their respective holes.
Some heat on the heads first and a sharp blow to the screw head will assist in freeing up those screws, if there is still some of the cross head pattern bit left to bite into.
 
Ok all....I've about given up on getting the forks out. Everything is loose, I've tried to spread the pinch points on the lower...trying to drive out the nut/spring downward. All I'm doing is compressing the spring. It acts like it's moving and the n at some point the spring rebounds.

I've let it sit with PB blaster but still can't seem to get it farther than halfway through the fork ear. Still too rusted?

You're going to replace the top bridge anyway so take the big nut off the top of the steering stem shaft and just remove the top bridge. Then you can remove the rubber fitted spacer for the fork ears and shine a light down inside the fork ears to see how much rust there is on the upper part of the fork tubes.

Assuming it's this one (#9), it goes inside the cover on the kickstart shaft

Thank you! About to put the engine all back together....plunging in!
Don’t forget the antiseize if you’re running new hardware, and drop your torque values a little for the stainless hardware with fresh antiseize on it. I’m pretty sure spec is 9 ft/lb so you don’t want to be slamming those home at gudentight “feel” - aluminum threads are soft.
 
Thank you!!
Ancientdad is right about removing that big capnut then the upper triple clamp first. Then the fork ears can slide up and off. I was amazed at how much rust was in my chrome fork ears, also rust on the fork tubes, which I removed with a long strip of emery cloth. After that a flat blade screwdriver can be tapped into the lower triple clamp slits to loosen them just enough that the fork tubes will slide out easy.
Don't unscrew the steering top cup under that capnut until you lay the frame over a towel to catch all the greasy loose ball bearings.
 
IMG_3281.jpegIMG_3281.jpegSparckmoto wiring harness. Where do the brown/white wires from each gauge go? I have a brown/white from the harness and a brown with female from the harness. Am I missing another couple female connectors? I knew I'd be intimidated by the wiring!
 
Thanks ...I do have a couple of diagrams and even a simple one but I'm just not understanding it. Do the brown and white wires simply get hooked up to an open black power connection ?

This brown with white appears to come from the right handlebar switch, and dash lights are illuminated when the headlight is on. Is there not a 3 or 4 way connector at the end of that wire?

And, the solid brown female-ended wire is for the running (parking) light for European applications, not used in the US
 
There isn't....but it's a replacement switch.
IOW, not for that model? or not OEM?

Pretty sure the black wire going into the right handlebar switch is intended to power the brown with white and distribute to the other bulbs through that brown with white output from the switch, so you'd connect all of the brown with white male ends to the one from the handlebar switch with a female multi-connector.
 
Not OEM. The kill switch was broken so purchased from 4-1. I didn't even think about the fact that the replacement switch might not be wired the same way. It's also got a dark blue wire that I can't match up.

Dark blue is generally high beam on Hondas. 4into1 sells OEM-style replacements but it's almost as if they're a generic version, kinda one size fits all, so they sometimes don't have all the wires an original does.
 
Take your time and double check the connections with a mutimeter and test light. I cut small strips of blue painters tape to mark wires that are not the correct color or I am unsure about so I am not having to go back to recheck things multiple times.
 
Great idea. I finally got all wired up and seems correct...things are working. Then realized that the aftermarket brake perch I had to order for the Universal Right Switch should have gone on first. Got that perch in the mail today and realized it. So, removed the switch and wires from the handlebar.....now will go through that rough process again and hook it all back up. At least I'm learning some things!
 
Ok, I think in trouble. Engine is in the bike, all wiring done, will kick over with the starter...just bumped it after replacing the starter. Have not installed the carbs. Decided to adjust the timing with my test light after installing new points.

When rotating the stator I got to an are where it felt like it was binding a bit and stopped. After looking at this some more decided to use my breaker bar and see if this was just high compression as the head was reworked, valves replaced and oversized piston's installed. Well, the stator bolt unscrewed.

Was able to retorque it to 22 FP.

Decided I'd better look at the valve clearance so was rotating to LT and got binding again and stator bolt came loose.
When I installed the cam chain I made sure the horizontal index line was right and the line on the cam shaft was correct.

Do I need to take the engine back out and check that cam chain again? Is a piston hitting a valve?

What a learning experience this has been. Thanks in advance

Do you mean electric starter, or the kickstart? Because if you've already kick it over with the kickstarter and the cam timing was not correct, you'll likely have a bent valve already,

If whatever you feel will hold the engine still so you can unscrew the rotor bolt, then either the bolt wasn't very tight at all or it's a lot more than a valve stopping the engine from turning.

Well, we didn't get to see any of the engine reassembly so it's difficult for us to know, though your description of things certainly doesn't sound good.
 
I bumped the starter, not the kick starter.
In order to check the cam chain again I'm assuming there's not enough room to take the cover off without removing the engine from the frame?

Is it that easy to slip a tooth on the sprocket in assembly? I agonized over the assembly and checked it 10 times.

During assembly it's pretty easy to slip a tooth or two, not so much after it's assembled unless you don't put the tensioner assembly back on and adjust the chain before turning it over. Bumping the electric starter would still have enough push to bend a valve IF it was about to happen (within the distance of the starter movement of the crankshaft). And sorry but no, the top cover can't be removed in the frame. Aside from a valve being the reason you feel resistance, there isn't much else that could cause that unless the kickstarter gear was stuck in the engaged position and it's trying to turn the clutch and transmission (though I'm not at all sure how that would feel when rotating).
 
Well, just another hard lesson then. I'll give it a fresh look after taking a little time off and see what I've done wrong.

Sure appreciate the comments and steering me in the right direction.

I don't mean to beat a dead horse, but if you post pictures along the way, sometimes we can spot something you might not notice or be aware of. Aside from just the fact that we like pictures, it's how we've helped discover and solve lots of surprises.
 
Update: after a cross-country trip to visit our daughter and her family and clearing my head I dug into this again with the help of two friends who have experience with the bike. After removing the engine and taking out the camshaft again we started fresh. Turns out my issue was that it was incorrectly timed. We struggled a bit ourselves because all was well until we attempted to put the cam covers on. At that point it was off a bit....but we finally got it and all is well.

My issue now: Does anyone have a good source for tank decals? I noted today that CB Decals is closed for business until further notice.

At this point all is done with the exception of paint.
 
Back on....
All is buttoned up and the bike was finally running well until Saturday. (Idle only and some extra throttle only).
I'm now having an issue with only running on the left cylinder.

I've checked compression, spark and checked the coils. All ignition is new.

Plug was 'wet' with fuel previous to that day and I reset the float level on that side with resulting start and ran ok.

Since Saturday I've rechecked timing and am on the marks for left and right with my test light.

Both carbs were rebuilt with a kit from those guys in Houston. But I still have the original brass. I'm noticing that now the left side is boggy. Do I pull the carbs, run them back through the ultrasonic cleaner and put the old brass back in?

I have had issues with the tank cleaning....I've had to reclean twice when I plugged the petcock thinking it was clean and it wasn't . I've just cleaned it again and have replaced the sintered brass filters with paper filters.

Just wondering if those 'new' jets are not very good. Past this I'm stumped....IMG_3776.jpegIMG_3777.jpeg
