I don’t think that’s going to work out on a weld. I would look for a new casing. It’s just so far worn even if you had it repaired finding the center point of the hole would be a tough one. And if it’s not perfectly centered then it’s going to wear and tear again.

That’s why you have members here to help us all make educated decisions!

Wow timing marks already for a 2019 what happened ? No warranty ? I was able to pull up few pages for a 2018 model. I hope it helps.

That’s a great post @scotty2hotty01 I am a big Honda fan. Yes CR was the initials. I hand my first cr80 and it was a great bike. Ran the heck out of it and quickly went up to a 125 then 250 and swapped over to the Kawasaki where I raced my as* off for a few years. Then off to ATV’S...... Still like Kawasaki but always loyal to my Honda and always looking to figure out the next brand and project which I’m hoping will be a Suzuki. It’s really the only atv I’ve yet to get my hands on. We will see what happens, right now I have this Kawasaki Mojave on the table and have had zero time to play with it. #Quadcrazy

I’ve had one of these bikes. Aside from the obvious things I pointed out in my previous post one thing I had to constantly do was change the plug. Or at least pull it and clean it. You jogged my memory on this. Try this. Go buy two spark plugs. Run the bike as it is and the next day see what happens when you go to start it. If it does not start right up swap the plug for a new one and see if it starts up. Next day right out of the gate put a new plug in again and see if it starts right up. If so the plug is getting fouled a bit lessening the spark. Why ??? Could only be a few reasons.... These engines are not really well built and oil gets into the head though valve seals or rings etc. Mine always blew a little blue smoke out of the exhaust. I was convinced oil was getting into the head. Also I leaned out the carburetor a little and it helped but not too much where the engine ran like crap. Maybe you can start there and see if the problem gets a little better with adjusting the fuel air screw first.

If your able to, what I do is find an old cheap screwdriver and cut the shaft from the flat tip down about an inch. Then reconnect them with a tight fitting piece of rubber hose. This makes the screwdriver flexible and can make a nice turn. If not they sell a small right angle flat tip screwdriver.

Thanks brother. You would not believe how many old tanks are still on the trails today. My oldest bike up until not too long ago was an 86. Sold it and it still runs great. I love the new bikes and the technology put into them today but to be honest if it were not for problem codes coming up on the screens pointing owners in the right direction we would all be screwed! Not a lot of people know what to do today when problems arise. On our older bikes we have the usual suspects. Carburetor, CDI, stator and ignition coils and general wire failures. Unless it’s mechanical like valves and timing issues. But either way it’s limited to these above listed items for the most part. Other than that with proper maintenance they will run for decades.

I would double check that the choke is working properly. Then I would assume that the carburetor is loosing its fuel. Where it’s going is the question. You could also have a crack in the rubber boot connecting the carburetor to the engine.

Your welcome but it’s no big deal. The smoke coming off of the engine on my bayou was the small valve access caps on the top of the engine. May not be your problem but this is what I did. First I bought a can of gunk engine cleaner. Follow the directions on how to use it and clean it good. This way you can see where the oil is coming from. Two caps have o rings and they flatten out over time. I took mine off left the o rings in place. Cleaned them from any grease and put high heat silicone and re installed. Again this may not be your problem but worth a look. You will get the hang how to do things on the bike just take your time and ask if your not sure. Put a piece of cardboard under the bike so you don’t stain the floor with the dripping oil. My son didn’t know much about atvs and two years into it it’s a great pass time hobby we have now. We find older neglected or garage buried bikes and fix them up and bring them back to life.

Could be a tired relay or bad brushes on the starter. I would start by loosening the connections up on the starter relay clean them and re tighten them good. Do the same thing on the starter wire on the starter. Then check the ground cable at the battery and where the black wire bolts to the frame. If this does not clear up the problem then go with a new relay and a set of brushes. Might as well buy both, they are cheap enough.

That’s your carburetor bowl overflow. It should run down to the bottom behind the engine. If fuel is coming out then the float in the carburetor is having an issue. It’s not raising up and pushing the pin that shuts fuel down. Maybe a quick carb rebuild may be in order. Oil issue, drain the oil out and might as well change it. There should be a sight glass on the side of the engine or a dip stick. Find it and fill it back up accordingly.

I’ve seen these arduous. Maybe it’s worth a shot ? Festnight Welding Rods Low Temperature No Need Solder Powder Welding Brazing Rods Welding Wire Flux Cored Welding Accessories https://www.amazon.com/dp/B07Q83FVJK/ref=cm_sw_r_cp_api_i_l5xeDbTBG6N3V

A good welder can take care of that. It’s a soft metal but I think a good heli arc welder can do it.

My answer was you can add a stand alone breather to the back of the carburetor only if you don’t have an existing oil breather line going to the old air box. If that’s the case then you need to keep the existing type air box. I did this on my Polaris 90 and it worked. I had to adjust the air fuel screw a little. This is the type I put on from amazon. 45mm Universal fit"Turbine" Air Filter - Motorcycle Scooter Pocket Bike ATVs - Blue (Model 10410-02) https://www.amazon.com/dp/B01DWGRL14/ref=cm_sw_r_cp_api_i_6YseDbM4GBSQ3

The other hoses most likely don’t connect to anything. They are breather and over flow hoses. They are supposed to run down the back of the engine and hang. If it spits oil out it really can only be from a few things. You over filled the engine with too much oil. The bike was tipped over and oil got into the over flow hoses. The engine breather line that goes to your air box is clogged.

I don’t think you will get back what you put into it. Your into the bike for about $500 right now give it take a few bucks. So tires, rocker arm, gas tank, starter battery l, brake cable etc. that’s another $500 minimum. So bam 💥 $1000. You would not get that much for it so now it becomes a personal/financial decision. Do I bring this bike back to good or do the basics like the brake cable, battery, gas tank and starter and move it along. Maybe the rocker so you don't sell it with a tick. Get $750 maybe $800 or more and you’ve learned a ton of knowledge and didn’t loose money only labor but you learned about this brand and how it all works on the next one and there will be a next one.

Thanks for the comments I appreciate it but im a small potato here compared to some of the other members. I was in need of some help on a problem I was having I came across Quadcrazy and got some really good help here. After that I was always checking in. So I think it’s about two years now I’ve been a member and countless bikes later I enjoy paying it forward and helping others as so many of our other fellow members do as well as having other members help me out on my problems.

No problem. Keep us posted.

Not too bad. I would say if you’ve kept it under $1800 your fine. That screw is located on the bottom of the carburetor in a very difficult spot. Some of the time they are covered by a brass plug that has to be drilled out. Your going to have to get a small/short screwdriver to get up in there to make adjustments.

That’s a shifter gear seal. You can try to get it out with a pick but that’s not very easy. You would have to pull the cover off and push it out from the back side. Hopefully you can press a new one right back in and you will be good to go. You will have to buy another side cover gasket. If the housing rim is dented and preventing the seal from coming out I would take a small dremil tool with a pencil grinder type tip and grind the dented edge instead of trying to tap on it with any sort of hammer etc. Post a pic of you can I’m sure some members here will have other ideas as well.

Considering the work you’ve done and the money you spent where are you currently at? Adjusting the carburetor is not hard at all. But make sure you are able to get to the air fuel mixture screw first and that it can be adjusted with the air box on and covered. All you should have to do is set the idle high enough so the bike stays running during this process. Then while the engine is running you turn the air/fuel screw in either direction. One way or the other the engine will start to rev higher. That’s the right direction. Keep turning the screw until the rev reaches its maximum and starts to decline. Stop there and go back a hair. Lower the idle to a good setting and you should be good to go.

What area of the bike did you find them ? There are breather hoses that do not go anywhere and just hang under the bike or go to the air box. Did you recently change the oil and maybe put too much in ? You will get oil out of these lines if that happens.

The best forum for ATV’S .

Are you sure the wires are correctly installed. The black bolted to the frame and the red going to a relay with two nuts on it ? And did someone possibly install the battery and put the wires the wrong way ?

Welcome to Quadcrazy! That’s a great bike to work on. There have been quite a few of these on the forum lately that have been project bikes. I’ve also had one that I overhauled and it came out great. So any questions you may have I’m sure we can help. Good luck.
