Great research and work! But I have to disagree on the stator. If the bike is running and has good spark I don’t think its breaking down. In my experience the stator is either good or bad. There should definitely be a reading on the ohms setting giving you exact numbers from phase to phase. Why your not getting that is a little baffling. You should buy an in line spark tester and plug it in and watch your spark as you rev the bike to see if there is a loss or brake down in the spark. It’s about a $15 dollar tool that’s a big help. Back to the carburetor: I would definitely drill out that plug covering the fuel air screw and pull it out. Check it out and clean the port well with cleaner and air. Before you remove the screw tighten it to a snug position and count the turns so you know where to set it when you put it back. My guess is it’s around 1-3/4 turns out from a snug spot. The fact that the bike sat, the carburetor was gummed up and that air/fuel screw was never taken out and cleaned leaves a question mark on the carburetor. I would start with the less invasive stuff right now and do some testing first so your not dumping money into it. Narrow down the problem so you don’t question weather it’s a fuel or electrical problem. Fuel tank and valve (petcock) clean and delivering enough fuel, carburetor rebuilt and good to go! No cracks or problems on the boot connecting the carburetor to the engine etc. if all that’s done then I rule out fuel or carburetor problems and move on to possibly an ignition issue. Oem/aftermarket: Carburetors: Chinese carburetors look great but don’t perform well at all. If you have the oem carburetor and it’s not cracked or damaged then it’s a good cleaning and rebuild. But it has to be properly done. One missed port or blockage will cause a lot of throttle issues. Floats set wrong, fuel air screw not right etc. Cdi: oem always. Used from eBay at the very least. Same with regulators Stators: I’ve used aftermarket RM and Caltric. No issues to date.

Just because a shop went through the carburetor dose not mean it’s going to be good ! We’ve all seen this. A guy who works in a bus depot as a mechanic can open an atv shop. Does that make him an atv mechanic? No! Sorry to be so blunt but that’s the way it is. Trust no one until you find the right guy and get to know him or her. My guess is the carburetor is not set right. It may have been cleaned and put back together right but If the air fuel screw is not set properly then it’s useless! I would get yourself set up right and locate the air fuel screw and turn it all the way back into a snug tight position. Then turn it out two full turns and start the bike. Then as the bike is running adjust the same screw turning it to where the engine revs higher, and that may be tight or looser until it reaches its best happy place and stop. And happy place means revs higher as you go, If it’s idling high after this then lower the idle screw. See what ya got after this.

No it should not be a problem or interfere with the cooling system. It should just expose the valves.

Have you checked the boot connecting the carburetor to the engine for any cracks or leaks ? If you have good spark then I’m leaning toward a fuel problem. It’s sounds like you did the right job on the carburetor but covering the intake starving the engine for air allows it to rev then it appears it’s within the carburetor. Is that bike gravity fed from the gas tank or a fuel pump ? The only other item I can take a guess at is the gap between the flywheel and pick up coil. Take a look and see if that gap is within speck. Double check the pick up coil is tight and all is ok inside that cover.

That’s a lot of miles! What’s your thoughts on the 450 as far as the top end smoke issue, just valve seals or are you going for the whole enchilada since its all going to be opened up? Or just wait to see what your mechanic recommends? Any good rides coming up ?

Hey Tahj you can take a look atv the timing mark on the fly wheel and pull the plug to see where the piston is in relation to the TDC mark but other then that I think your stuck pulling cam sprocket cover in order to see and make sure everything lines up. You don’t want to spin the engine and have the valves and piston hitting each other so be careful with the cranking too much.

Ok so the starter relay is clicking. That’s a good thing. Starter is not turning. Bad thing. So the starter relay could be bad making a shitty contact within. That’s my guess, however put a tester on the wire at the starter and see if you get 12v at the starter when you press the start button. You can also jump the relay quickly to see if the engine cranks. If so then put a new relay in and it should be done.

I see that in your picture. The stator on the bike in question has two yellow wires. It looks like a single phase stator which would only have two wires.

Hey Tahj. What’s the make model year ????

It should work or be close enough to see what’s what.

In order for me to properly see or say what’s going on is to find the diagram for that bike. After I have that it should be a breeze.

Starter clutch has nothing to do with it.

Wow blast from the past seeing that. This is a very addictive hobby. Especially once you hit a really cool trail ride with a ton of ppl. Enjoy it and most of all be careful. Ride safe brother.

Oem $79 ? My personal opinion not that it matters is I would rather a used oem then an aftermarket. That jumper pack is a great addition to the take alongs. It has a USB port for phones as well. There was a topic a while back about what we all keep on our bikes while we are out and about. You should look that topic up it’s super helpful.

That’s a great image @mikeexplorer I only see two yellow wires in his picture. So I’m wondering if it’s a single phase stator.

Bring a small jumper pack. I love mine and it’s saved me countless times. Finding a rectifier may be challenging. The aftermarket ones are not so good. I found one on eBay but you should make a move quickly based on the price. It’s oem as well https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.com%2Fulk%2Fitm%2F223522113944 Arteck Car Jump Starter Auto Battery Charger and 8000mAh External Battery Charger Car Jumper for 12V Automotive, Motorcycle, Tractor, Boat, Phone with Clamps, LED Flashlight, 300A Peak 2.5L Gas Max https://www.amazon.com/dp/B01DVSSCG6/ref=cm_sw_r_cp_api_i_UMcqDb0QB1Q33

So right now it starts with the electric starter no problem?

Nothing like riding in the dark. Have you checked your battery and gone over any wiring that could have shorted out? Check all the fuses as well. It could be your regulator or stator coil. But start with the basic stuff first and go from there.

I’m having a hard time locating a clear diagram for you brother. Maybe @Admin can help us out here. Not sure but let’s see.

Can you double check all the colors of the wires. I’m looking for two yellows and one brown ?

Ok the only wires you should be testing are the yellow to yellow and get a reading. Them each yellow to frame. Should get no reading. I have to look at the diagram for the pick up coil wires.

Looks like it’s all in tact. I have a similar problem here when I pick up old bikes are wasp and bees nests under the seat and plastics. Happens a lot. Double check that the float is not cracked and filled with fluid. It’s a bi*** to see but I just came across this problem. I put a flashlight on it and seen the gas inside. If it’s a black float shake it and you will hear it. Of just drop it in a bowl of water. It will barley float.

You shouldn’t get a reading from anyone of three wires coming from the stator to ground. What did you get from wire to wire?

It makes. A huge difference. The stator coil wires. Test all three. Each one to ground with a continuity tester ohms. You should not get a reading from each wire to ground. Second is to test each wire to wire with the tester on the same setting. You should get a similar reading from wire to wire. I will find the diagram and see if I can give you a hand in the mean time.

That’s a one piece cover as far as I knew. Can you post a pic I’m curious about the one on your bike.
