Default Exhaust valve removal

Is the Ctec2 the same as previous cat 800?
2 bolts and pull exhaust valve out to clean?

The easy answer is no, because of the side valves. I'm not sure what the service manual says, but one of the cylinders will likely need to be removed in order to extract the main exhaust valves to perform a full cleaning operation.

The reason a cylinder will need to be pulled is because there is a pin running through a hole in the main exhaust valve and connecting on each end to slots in the side valves. As the main valve moves up and down, that pin manipulates the side valves to move through their rotation. In order to remove the main exhaust valve, that pin needs to be removed. And in order to remove the side valves in the center of the engine, one of the cylinders needs to be pulled.

Theoretically, you could possibly leave the cylinders on the engine by removing the outer two side valves, remove the pin mentioned above, and then remove the main exhaust valve. However, if either one of the inside side valves happens to rotate ever so slightly without that rod holding it in position, you won't be able to get the pin reinstalled. At that point a cylinder will need to be removed so the side valve can be accessed and the pin reinstalled.

Basically, when you start with all the raw components, the assembly process goes like this....

1. put the main exhaust valve into its slot in the cylinder
2. slide the connecting pin through the hole in the main exhaust valve, centering it so that the same amount extends from both sides
3. install both side exhaust valves at the same time, aligning a slot in each side valve with the connecting pin
4. install the side valve covers locking the assembly together
5. install the main exhaust valve cover/cable
6. install the "assembled" cylinder on the crankcase

In the end, that connecting pin kind of ties everything together. That being said, there are a lot of moving parts to this exhaust valve system and a failure in any one of them will cause the entire system to fail. It will be interesting to see how this design holds up over time or how much regular maintenance will be necessary.

No need to pull the cylinder... Just remove the supports on the way..

Per the service manual, page 82...

NOTE: To remove the valve assembly and both side valves, the cylinder will have to be removed from the crankcase.

NOTE: To remove the outside side valve and main exhaust valve, the access panels, hood, expansion chamber, resonator, clutches, and the left-side spar will have to be removed.

Default exhaust valves

I believe the key words are both side valves. To remove the right side valve the left cylinder is in the way.

Ok,
Remove the outside valve cover (that don't sound right on a 2stoke), remove the side valve, remove the pin that goes through the main valve, remove the main valve similar to the Zuke engine. Reassemble in reverse order.
Could an issue arise from the inside valve? Could it move, making install of the pin impossible? Or maybe just some finnesing and wiggling?

I have not done this job, but looking in the parts book it appears that the side valve rod would need to be removed to get the main valve out. That's how I see it. I use the C-Tec oil in my Suzuki and have never had to clean the exhaust valves. Maybe that's A/C thinking not sure but it doesn't look like a quick job. A/C does offer a gasket kit for the top end maybe that's why???

As far as the pin goes there must be a way to align it,remember someone put that together at the factory and its meant to be taken apart, cleaned and reassembled.

The notes I identified are mutually exclusive, not inclusive, there is a difference. The first note is if you want to remove BOTH side valve, then yes, a cylinder will need to be pulled. The second note applies when you want to remove the main valve, then the cylinders do not need to be removed, but the other items need to take place.
