You guessed it. I adjusted the float and it's all good. I rode it around a bit yesterday. Runs pretty damn good! I'm gonna drain the oil from the engine into a nice clean container and see if there is any more debris in it. And, it needs a new a battery. damnit! Freakin $90. 😧

Sonuvabitch it fired up! It ran for a few seconds and I shut it off. Started it up and it ran for 30-45 seconds (no water in the radiator) and shut it off. Sounds like it runs like it's supposed to. I got fuel coming out of the carb, so I gotta check that out and the battery craps out very quickly. Progress tho!

Frank, I had a bit of an erratic spark before I took the stator and flywheel off. Do you suppose that all the metal pcs that were flying around in there had anything to do with that? And, I might just put it back on and check the spark. Will not having any oil in it have any effect on the performance of the stator? And I don't think that cranking it over for a few seconds with no oil will hurt anything. IDK. I will put assembly lube on the camshafts and rockers tho.

I found the specs for a 2009 ltz 400. This one is a 2003. IDK if they're the same. I have a tester.

I got the cams back yesterday. But, before I put all this back together I want to check the ignition components" IE stator, coil, pick up coil. Any info on specs for that?

Yes. Toy hauler. I can fit 2 4x4 quads and 2 bikes in it. Barely! And dum-dum. LOL

Whatchoo ride? still a few patches of snow!

No,no,no, I'm riding tomorrow! I prefer 2 wheels, but, I do it on all 4 sometimes!

I had to order a new woodruff key yesterday........so, I'm stuck until tomorrow. Tomorrow is riding day!!!! So, it'll have to wait until saturday.

Welp, it's going back together. I did my best to flush out any remaining debris. I spoke to HotCams yesterday and the cams are on their way. Inspector Woof says my work is a bit ruff, but, he signed it off! Lol

So, the update.... The camshafts are old Stage 2 HotCams. I sent them off to H.C and they are going to put some marks on them so I can time them properly. In the old days. H.C's put paint marks on the camshafts for timing purposes. They wear off over time. They're doing this at no charge. Just shipping. I think it's $15 total. ANyway, the pcs of metal debris that came out of the engine is the starter sprague or starter clutch. Ya.Came out in many many pcs. Not good. However, I have removed the head and the valves look good and piston and cylinder look great. This thing right here is what is broken. https://www.ebay.com/itm/New-LTZ-400-Quadsport-Starter-Clutch-for-Suzuki-LT-Z400-03-14-LTZ-400Z/231436719164?hash=item35e2b4143c:g:gvoAAOSwwTlUnK5g This is what's left!

Most 4 strokes have a compression releif mechanism on the exhaust cam right? This doesn't have anything on the ex cam. Nothing. It looks exactly the same as the IN cam. ANd if there was a spring on the ex cam, how would it get to the stator? IDK. I'm about to light this thing on fire! LOL

Yes, exactly. That round pc was stuck on the drain plug. What kind of seals are in this engine? It doesn't have crank seals like a 2 stroke does it? Water pump seals come to mind, but, there's no water in the oil or oil inthe water. It hasn't leaked any oil either.

Heres the pcs that I found around the stator. There's parts of a spring that would be found on an oil/water seal. The drain plug.

I pulled the stator cover and stator off today. It looks like the key on the flywheel is ok. Is there a way to check the timing with a timing light? I really don't know. If it was an old car or truck, then.....LOL. I'll post up some pics of what I found inside the stator cover a bit later.

Oh, ya, the lobes. They seem to be in about the same location. If they are aftermarket cams, then, the keyway is probably irrelevant.

Didja look at the pics that I posted? Those 1 2 3 marks aint on there. That's the crux of the matter. 😉

I'm going to email hot cams inc. and ask them if these look like their stuff. These are definitley not OEM camshafts. IDK what else to do.

Hmmm IDK. If you look at the diagram that you put up, and also on the video, you will notice on the intake cam that the keyway is at about 1 oclock and 11 oclock on the exhaust. Now, look at the first pics I put up before I took it apart. On the intake the key is at about 11 and on the exhaust it's at about 3 oclock. Fuuuuuuuu... something smells here. LOL

Here's the back. It ain't on backwards

There are no marks on the sprockets other than the IN that you can see at about the 10 o'clock position in the first pic. There is an EX stamped opposite side. Same on both sprockets. You might be onto something about them being on backwards. I'm gonna pull them out.

So ,here is the cam sprockets. This is at TDC. I didn't do any of the paint. Notice those bolts? The white dots on the cam lobes denote the center of the lobe. I did those. Aren't those supposed to be 180 from each other at TDC?

Backwards?? that may be it. These cam sprockets have bolts in them that look out of place. Like someone "made it work" at some point. I'll put some pics up later. On this video there are no bolts on the cam sprockets. Weird

I may have to take a look at that. It did the same before I took it apart and checked the valves. Someone has had it apart before that, tho. Read my 2nd post. It doesn't have marks on the cam sprockets like described in the Y.T vids that I watched.

Thank you. It seems like the spark is ok with a new plug. But also when I crank it over it struggles when ever it hits the compression stroke. I thought it was a weak battery so I got new larger lawn equipment battery, fully charged, and I hook it up via jumper cables and it does the same thing. You think the starter is bad/weak? It pops and acts like it wants to start, but, it seems if it was spinning faster, it would. I wonder if I could bump start it with a truck or quad? That might answer that question.
