CL350 Doesn't Have Any Power

[drh994]

OK, I'm starting to wonder if something else could be the issue. I checked the plugs. The right one is dry and tan so that tells me it's getting the proper fuel/air ratio. I pull out the left spark plug and it's wet. So am I chasing down a timing issue when I'm really having a carb issue? If so, my thought is that the carbs might not be synced properly. My next question, what's the best way to sync these carbs since I don't have a vacuum plug on the carb boots of this bike?

The valves need to be set correctly regardless of any other problem.

But just for interests sake, check for spark.
Pull the plug and put it back in the boot, set it so its touching the engine block and kick it over and see if theres a spark.

It's getting spark, a really good spark actually. I started messing with the carb some more and worked on getting them synced. It's helping the bike A LOT so I'm starting to wonder if that was it all along. I'm running out of time to mess with it more today but I'll keep on that track for a bit and see how it goes.

The best thing I was able to do to sync the 350 cv carbs was adjust the throttle cables one at a time until they engaged at EXACTLY the same time. I mean exactly. So twist the throttle incredibly slowly and look for movement, when they move in unison you should be okay-ish.

Here's the latest on my issues. I got the bike to run ok one time around the block then it went back to the same old issues. Now I can't hardly get it to start. I did the compression test again. The left cylinder went down some. I'm getting pretty convinced that I will need to open up the engine and do some internal work at this point. I want to make sure I tackle the correct issue. I poured a bit of oil into the left cylinder and tested the compression again. I didn't get a change in the test.

So am I right to think that this tells me I'm having valve issues? What all do I need to get if I'm going to do this kind of valve work? Should I get valves and springs? Should I get rings and do that as well since it's open?

Yeah that indicates valves.
Theres no need in purchasing parts to throw at the problem, you need to take the valve cover off and see whats going on in there. You could have a bent valve, you could have a bad seal, etc.
But Im still curious why your valves won't adjust to spec thats where I'd look first.

On the left cylinder, I can get the intake valve adjusted right but I can't seem to ever get the exhaust to adjust at the right timing on the rotor. Could that be caused from a bent valve?
