Great video man

[@codynorman7744]

Having a bushing style bearing is actually preferred for a turbo application as a roller bearing cannot contain crankcase pressures that are increased by boost. Also every car out there has a normal insert bushing for the crank. Roller bearing don't exist on cars for main bearings. Also it's the microscopic layer of oil on a bushing type bearing that is the bearing 😊 . I'm also curious what type of bearing you feel they should use? It's a pressurized oil system and needs tight clearances fpr proper oil pressure. That's why 2 stroke utilize roller bearings for the crank as they do not have a high pressure oil system. In my humble opinion

[@piquat1]

"That's why 2 stroke utilize roller bearings for the crank as they do not have a high pressure oil system." I was with you until there. A two stroke uses the crank case as an intake tract. When the piston comes down it decreases the size of the crank case, pushing air/fuel into the combustion chamber via ports in the cylinder walls. A common reason for a no start is the loss of seal, ie. not being able to pressurize the crank case. They use roller bearings yes, but having a crank case that won't hold pressure is not a result of that. Two strokes still need to be able to pressurize the crank case, roller bearings or not. While a 4 stroke will run with a leaky crank case, a two stroke won't even start.

[@bruceh3786]

I'm new to the CFMoto world and SxS so I found this video very informative. Thanks! I have been wanting to see what a V belt drive looked like so this video was a great help. It would be great if you could show the split case and explain how a wet and dry clutch differ and the advantages and disadvantages of each. I have a 2022 ZForce 800EX made in August 2022 and was told it has a dry clutch. My understanding is that engine was always a wet clutch until mid 2022 production. I have not found an explanation for the change.

[@R.N.GPerformance]

Yes CFMOTO changed it. Your unit now resembles this block.

[@swedishpsychopath8795]

I've bought a CFMOTO zforce 800 ex engine as a spare engine for my zfore 800 ex UTV. It is supposed to have a broken drive shaft and would need to be rebuilt with new rod bearings and stuff (I guess). I have't picked it up yet but for 60 US dollars (yes SIXTY for an entire engine) I couldn't let it pass. Will pick it up myself in about 4 weeks time to reduce the risk for further damages. My plan was to pick parts from it if ever needed - but would it be possible to rebuild it to working condition? How much will I have to invest in parts? Would I be able to do it myself?

[@seamonsterco7570]

I really don't think that bearing is going to suffer from a little boost. Make sure everything is balanced to avoid any deflection and give her 5psi. Fuel and tuning would be the critical factors. Possibly have to borrow a map sensor capable of providing a positive pressure reading. It's a basic 5v sensor signal at the end of the day. I have been pondering the idea. My problem is that I only have 16 miles on my overland. Do I want to light my warranty on fire? Maybe. 😀

[@R.N.GPerformance]

Lol. I’m sure it would take 5psi but 5psi isn’t fun lol

[@seamonsterco7570]

@R.N.G Performance 5 psi would be an additional real world 24hp. That's like strapping a cforce 500 on the back! I'm honestly thinking of going electric. TorqAmp possibly. Would easily make 5 psi on demand with our small displacement engines. Would be relatively safe as well. No oil lines. Less heat. TPS activated. You should see if they would donate one to the channel! I think alot of ppl would donate to design a kit. I would.

[@R.N.GPerformance]

@@seamonsterco7570 those things are cool. But we don’t have the charging system to keep up with it.

[@seamonsterco7570]

@R.N.G Performance It has a standalone lithium power supply. 48v. You could charge it with as little as 1 amp. Obviously the more current available, the faster it would charge.

[@backwoods_utv83]

With the motor being v twin can you get more power then the same size on a inline motor. By keep up the videos love watching them!!!

[@R.N.GPerformance]

I doubt it but we’re going to see what’s possible for sure.

Hello, I like your videos very much. Thank you. I have a CF 625 engine, but it is very difficult to shift gears. What should I do? Can you give me some advice?

[@jjmaynard76]

If you're doing just a top end on one of these 1000cc engines from CF Moto, how do you keep the timing chains in place on the crank so is not to mess up the timing when you're putting it back together?. I have a 22 C-Force overland that I'm going to have to re-ring due to dust intrusion. Thanks! Thanks for the great content!

[@R.N.GPerformance]

Thank you 🙏. You will have to re time it. Your going to want a book because timing these engines are a little different.

[@jjmaynard76]

I have the CFMoto service manual. So I take it from your reply I need to plan to remove the covers on both sides for crank access to retime it when I go back together?

[@102Montana]

In MT, and don’t trust the local dealer. Have a MC / ATV mechanic shop here in town. So, I planned on using them - although they aren’t CFMOTO gurus. MY QUESTION: Should I buy a specific CFMOTO book to make life easier for them (in the event I have an issue). If so, what do I buy for a 22 Overland?

[@R.N.GPerformance]

You would just need the repair manual

[@dustindiller4592]

do you know if the 950/1000 motors fit on the 2020 zforce 800 trail?

[@andreiionut95]

Hello old friend! I own a zforce 1000, 1st gen. Due to plain shaft bearing being worn, i had to crack open the engine! Replaced everything, put the engine back on, it starts, but it starts in only one piston, the one from the back of the. The front piston, from the cabin, blows unburnt fuel out of the exhaust, and i can feel a lot of gas smell. While pulling the spark plug out of the engine, i saw that it sparks only when the engine starts, then it stops. I have no error on the tester. I changed the spark plugs to each other, but the problem remains on that piston. I really don't know what can i do anymore...it got me out of my mind...

[@jjmaynard76]

Can the top end be done with the engine in the frame? I have a overland 1000 needs rings. Thanks!

Oil pump. These gears don’t fail very often and if they do and your oil light comes on shut down your motor and it will love to see another day. Broken pump gears don’t trash motors. People who don’t pay attention to their dash warning lights trash engines. Plastic gears are used in many many engines and for the most part out last steel counterparts.

@@R.N.GPerformance Thank you for the reply. I am not sure if I have a bad gasket or not. I thought I had coolant in the oil. Now it appears to be gone. I did four oil changes and ran it about 45 minutes after each change. The real watery oil is now gone. I did use 10w 30 and not 15w 40 like the owners manual said. Long story short after four changes with 15w 40 I ran it for an hour last night and did one more oil change. It's looking normal again. So is it possible that the 10w 30 that I used became real runny? I probably ran that oil for at least two maybe three months. Lots of real short runs and a lot over the cold weather. My neighbors thinks I got condensation in there.

Is a engine that's had all the coolant and then some ran through it until it stalled worth rebuilding?or buy a used one for3k? My cousin's I think water pump seal went out and the rad it packed with oil and the engine drained coolant then milk shake after. It's a2020uforce 1000.
