The title pretty much explains it all. When using the starter I can hear it spinning but not engaging the engine. The wheels also do not engage with the wheels when the clutch is out. The motor has compression if that helps.

I am new to engine work and repair and I bought this quad with the idea of fixing it up (not knowing the full extent of the damage). The previous owner said it ran but sat for a year (I don’t believe that for a second after opening it up) and had bought a few new plugs and a starter motor, none of which fixed the issue.

Any help would be greatly appreciated!

I have attached a few pics of what I think could be wrong.

So when in gear and you let go of the clutch its like its in neutral and noting happens? Are you using the pull start to crank it? Aren't those semi auto or do they actually have a clutch?

Posted

Yes. When I push the quad with or without the clutch there is no engine resistance. This type of quad has a CVT so there might be something I am missing. There is no pull start (only electric). Thanks for the reply.

Oh and I am cranking it with a wrench.

As long as it’s in neutral it should not have resistance with or without the clutch.  So if you put it in first gear or any gear for that matter the engine should resist with the clutch out and very little resistance with it pulled in.  So first I would go through all the gears one by one and see that it’s changing gears properly. After that I would look at the clutch actuator that expands the clutch. It’s the lever on the side of the engine where the clutch cable connects to.  There is a shaft back there and that rolls the clutch out. Based on the metal chunks it sounds like you maybe blew a gear.

As I stated previously the quad is equipped with a CVT and does not have gears to run through. Also the starter is not connected and when I crank the engine the large gear on the crankshaft that is connected to the starter gears slips past the shaft. Is that normal?

The quad has a clutch and a CVT. The clutch does not appear to do anything as the engine does not seem to be connected to the wheels regardless of whether the clutch is pulled in or not.

The clutch is only for starting and stopping, not for running through any gears.

How does the lever feel when you pull it in? There should be a spring loaded type pressure.   If so and you can see the clutch expands on pulling the lever then it’s working. It’s most likely something internal. Maybe a shaft or gear and will involve pulling the flywheel and exposing as much as you can without splitting the engine.  If not then your going to have to yank the engine. 

But before you do all that. Have you checked the drivetrain to see that any of the drive shafts and yolks are not broken including the rear differential? 

Start with the simple stuff first before you go deep.

As I said before I am new to this kind of stuff and completely failed to notice the clutch cylinder. Would this result in the clutch not disengaging?

Thank you for your reply.

I am totally confused now. If the quad does not have a clutch then why do the wheels not connect to the engine? And how could I bump start it?

Back to the starter not engaging I believe the thing that I took a picture of in the second to last image is shearing off (if not completely gone already). Could that be the cause of my issues?

Thanks a lot for your help.

You can’t bump start a centrifugal clutch.  It works on expansion and revolutions. The faster it spins the weights in the clutch expand grabbing the housing and the wheels spin.   

Im not 100% familiar with your engine without looking at a manual as well as the angle of the pics you sent but if you removed the clutch off of that shaft and your seeing shear marks I would guess that’s your problem.

So based on the pics it looks like something was taken off of the shaft in the pic? Is that correct.

On the other side of the engine, is there a cover that’s much different ? the clutch assembly is generally bigger and it’s a  larger size cover. Like I said I’m not familiar with that engine but the premise is pretty much the same as other engines.  

I’m just wondering if you have taken anything off.   

Is that the left side of the engine your showing ?

I did take off a gear and the flywheel from the shaft in the pictures above. The left side is very different from the right side in appearance and size. Thank you for all of your help today but it is getting quite late where I am and it is difficult to see with my dim garage lights. I will continue working tomorrow.

Here is a picture of the left side of the quad. I believe it hosts the CVT as the end of the cover leads to the chain that turns the wheels.

So when you get back to work on the bike you can test a few things.  

1. Bump the starter button and see if that gear coming from the starter spins.  If so then you may have just lost the keyway that holds the flywheel and starter gear on the shaft  or the nut came loose holding the flywheel. Not likely but possibly.

2. That break lever your referring to when you say you need it to start the bike has a pin that’s sticking up to lock the brake. The reason you thought it was a clutch I’m assuming is because you cant start the bike without pulling it in.  That’s just a safety in place so god forbid the throttle got stuck and the bike started it would take off. This brake safety stops that from happening.  

The side cover with the clutch inside can be taken off and inspected and we will help you walk through the process.  Just take care of the starter problem first.

I don’t know what happens when I use the electric starter but when I crank the engine with a wrench the gear on the crankshaft connected to the gear on the starter slips and does not engage the crank. Are you sure that using the electric starter when the cover is off and without oil will not damage the engine.

You don’t want to continually crank the starter over and over and for long periods of time.  I would pull the starter out and see what’s going on. It may be a busted shaft or whatever but pull the starter out and see what’s happening.

Sorry brother I was working.  I would have to look at the repair manual to see exactly what’s going on but my guess is that your going to have to pull the starter out and see if everything is in tact and not broken. If that all checks out good then your starter clutch/bendix is bad.  eBay prob would have one.

      Hello all! I’m new to the 4 wheeler world, but not new to the mechanic world. I was a diesel mechanic for many years and last year got into jet skis. I just bought a 1987 Yamaha moto 4 350 and now learning the ins and outs of 2 stroke engines. Looking forward to learning all the things.

      Hi could someone please help me, not to sure what engine this is

      Question for you guys. I have a 98 bayou 220 that I picked up cheap cause it's wasn't running. So it's has very low compression. It is getting spark and fuel. 
      What should my next course of action be? Any other tests I should perform or where to start looking?
      Thanks in advance.

      First post here need some help/advice. I bought a 2001 king quad 300, vin number JSAAK43A212111871. I have been trying to do some basic maintenance as it runs but doesn't idle all that well . I want to take out and clean/repair the  carb but when looking for parts it ask for model X Y K1 K2. How do I know which model I have? I have tried some vin decoders but they haven't told me. If anyone could recommend a carb rebuild kit for my quad Id appreciate it. Also any tips on tracking down an owners manual?
