Just so you guys know, I'm taking everyone into consideration but I'm not going to dig into things that I don't want to at the end of the day. Whether one person or everyone thinks a pump or the valves or whatever is the issue. I'll check it out. But I'd appreciate it if this didn't turn into who knows more. I'd rather people be able to follow the thread and hopefully fix their issues as well

Exhaust valve

I have left the bike for the night I've been on it for four hours but I'm going to get the intake cap off tomorrow and we will see if opening it up a bit helps So a feeler gauge would be more useful just checking the valves for wear or setting them new but it is better to go by ear when adjusting them?

I may just do that, I have to get into the intake valve to check it out first. And I also want to get some feeler gauges as well so I can make sure they are set properly and if that doesn't fix the issue I will take the head off to get the valves replaced. If I have to spend a grand or so getting the bike running for 20 or more years I will. It's a fun bike and they're fairly easy to work on lol

I broke the ratchet trying to get one of the damn lugs off the tire so I could swap it lol it was a cheap mastercraft I'm gonna get a better set eventually but for now I just buy what I need, Im a carpenter by trade so I have a decent assortment of tools to do what I need. For most jobs just not much for mechanics work I guess my hand tools are gonna have to get upgraded I'm gonna tell my girlfriend you guys said I needed them though lol she thinks I have more than enough tools

I also think you guys were right about him knowing something's off (maybe) because the intake valve screw cap is stripped, lucky I have one on my parts bike but I don't want to leave the engine outside without one so I want to put the stripped one on the parts bike. Any ideas to get that guy off there? Also I broke my half inch ratchet lol I will have to grab one somewhere.

By that I mean do I have to take the engine out I do, but if you think the valves are going to cause an issue down the road anyway I might as well know how to replace them if not do it now. Also I'm a dumbass. I was looking at the exhaust end. (As I said before it's my first time digging into an engine lol)

Okay well if I'm gonna mess around this much how do I go about replacing them?

I will double check but I believe that's what it was set to when I last touched it

So I took it out a couple turn and it bogged worse, then I turned it in a few and it got slightly better but I still think maybe worse than before. But it runs better with no movement? I'm gonna keep playing with it a little bit It wiggles a bit now and I can hear a light clicking now, I'll get it back together and fire it up. Stay tuned After

It wiggles a bit now and I can hear a light clicking now, I'll get it back together and fire it up. Stay tuned

That was actually a very helpful video for me. Thank you lol I'm gonna watch a few more to help with my tuning skills, And for the valves am I able to access both from the same side of the engine or is the rubber plug on the opposite side of my engine also supposed to come out?

I'll check that next, I'm checking the valves right now and I don't have a feeler gauge but the valve on the spark plug side (I assume the intake) seems pretty tight. I feel a slight wiggle but not much at all and I know the spec is 1-3 mm so I think the intake valve is okay, (I will go back with feeler gauges when I can get a set) But from what I can tell intake is good, now I just have to get at the exhaust

Eventually I'd like to take it up a notch but for the time being I am more focused on getting it running right and knowing that everything is 100% before I jump into adding other things or upgrading multiple parts, I am going to check the valves now if I can get to it. I'll keep everyone posted. I'm checking this thread often through the day as this damn bike is on my mind all day lol I just can't get over it running better without the airbox cover. It doesn't make sense to me, Maybe the exhaust valve is stuck open so I don't build any back pressure? Idk. But I'm gonna check and I'll post some pics Also kinda flattered me when I read that lol thanks

Ok I'll check it out tonight

As far as I can tell yes it is OEM. Everything matches up to OEM diagrams

So what do you suggest I do? I plan to keep the bike for a while if not indefinitely. So if I am going to get it running right I feel I might as well fix everything along the way. The CV carb is that a different style or is it a part? I'm not too inclined when it comes to mechanics but I'm not a loss either I've never touched a bike up until I tore into this and my ltf250 so any advice or input is appreciated. Also thanks for all the help this far. It has been a big help (especially getting comfortable with taking out my carb and the small components) I feel pretty confident with everything but the internal engine now

I will try this when I'm off work. But I am just puzzled. I don't think it is a fuel issue because it runs better with more air so wouldn't that mean there is enough fuel? The bike runs fine at idle it's only when the rpm start to climb

I'm thinking the intake valve as well. In going to try adjusting it tonight. The stator is charging (sometimes overcharging) I've replaced the resistor and coil, plug and air filter, eventually I'll have gone through the whole bike. But a fues issue doesn't make sense to me because it runs like it's deprived of air not fuel Lol me too

Well lol I took the coil off and the rectifier from the parts bike thinking maybe. Because I tested with a voltmeter and it was low and would drop below 5 at times then back up around 12v But it made no difference so I guess next is this lol Maybe I'll see if I can snag the one off of my parts bike and see if that helps

No I haven't messed with the valves yet, I am pretty good at figuring stuff out but engines have always been hard for me because I can't see the actually process happening. I just recently got into figuring it all out with a small motor and now I'm trying with the quad. If any of you have some experience checking/setting valves can you give me a briefing? I intend on doing everything I possibly can myself before I take it to someone else. You don't learn what you don't try eh. I'm pretty sure I have to replace my stator as well but can't find any videos on a sazuki king quad 300 stator replacement (although many people say they've had to) I'm trying to check as many of the things I come across as I can, I have a lt-f4wd and three parts bikes for it as well as my king quad and almost a full parts bike for it. And I know many parts are interchangeable but any part that is not working if I don't have it I will buy. I'd like to make this quad a fairly reliable fun trail bike if I can. Because the thing was awesome when I got it running the first time. I fell in love I think

Can I test the lead to the spark plug?

I have replaced the spark plug with a new one twice to be sure. It fires up pretty easy. First pull or two or with estart

It changes the way it Boggs a bit but I seen no difference in the rpms unless the airbox cover is off

But it was running great without one shortly before all this. And now when I remove the airbox cover it runs pretty well but backfires here and there
