Ok,

So before I check fuel pressure and compression I decided to have another look at the fuel injector.
So I checked the injector again to see if it was getting power, which it was. I checked the spray pattern and cleaned it again and installed it back on the buggy. When I tried starting it again it seemed like it wanted to go but no go. I noticed while it was trying to start that the air intake was puffing out exhaust/smoke. What would cause that?

Stuck, miss-adjusted or leaking intake valves or..more often..a valve timing issue...as in she's jumped one tooth. Better check because 2 teeth and the piston hits the valves and then its a rebuild.

ok

I will check that out.
i cleaned out the throttle body this evening and it was pretty dirty. Also the exhaust pipe and u pipe which were full of grime. Almost started but no go. I will definitely do what you suggested.

Thank You

Does anyone have a repair/service manual for a 2013 cfmoto zforce 600?

Ok

I checked the valves and both were tight/closed. Adjusted to spec, but still won't start. Did a compression and got 120psi and the manual states 145psi. As it was turning over air was coming from the air intake tube coming from the air filter and it blow off the air intake hose from the throttle body.

I would say it's jumped time them. Check the valve timing now.

[FredC]

Ok
So if it did jump and valves are off again, what does that mean?

Means its likely the piston did hit the valves which has damaged them as well as the rod bearing and of course the reason it jumped time in the first place.. which for CFM is usually a failed cam chain tensioner or stretched chain..or it may be one of those that has a miss-matched chain and sprocket. Means at minimum a top end rebuild. At most a complete rebuild.

[FredC]

Oh my!!
Not sure if it's worth that.

Also as a note. I had the one way bearing replaced this summer because the starter wouldn't turn the engine over. Would that throw the timing off if they didn't put it back right. Because I started having trouble the first ride after that and it would leak some oil/ spit it out from underneath the throttle body. In that area. Also the u shape pipe coming off the throttle body to the air filter had oil in it.

The rotor would have to have come off and if CFM uses one of the coils for a pulse coil and it wasn't torqued properly, it could shear the wood-rift key and it would be out of spark timing, not valve timing. Even though I believe CFM uses the CPS for it's timing it would still be worth a look.

[FredC]

So much appreciate all your input and help on this.  I guess now I will have to take it to a shop to get it checked out.
Once again thank you so much.
God Bless and have a Great Weekend!!!!

Good luck. Hope it's something simple....and cheap.

Hey,
Something just came to me while reading about the timing and valves.
When I got my sxs back after the oneway pulley was installed for the starter to turn over the engine, I
noticed that the screw on the timing chain tensioner was missing. At the time I didn't think it was anything. Just watching a video and reading up on this, you can lose oil out of the tensioner if the screw is missing and your timing can go off.
Is this correct?

Not really sure how the tensioner works on that one but if that screw has anything to do with setting and maintaining tension, yes there would be a problem as well as having an oil leak. Refer to the service manual of it's R&R.
