Yamaha 200 worth it?

[78z2+2]

I will look in to wet sanding before I paint them, thanks for that info. I was actually going to try to make another gasket to fit inbetween the rubber and the head, and also add some silicon gasket maker to see if that would fix the problem. Cheap, and worth the try. @ MonroeMike yeah that little rubber part under the metal intake is the part I need. I already emailed the seller to see if he would just sell me that part, but have yet to hear from him. Again, thanks for all the help guys. This website is top notch

Nice job man! Put some pics up so we can guide you better on what to do. As stated, painting plastics is not a very good idea.

[78z2+2]

I'll be sure to do the wet sanding before I paint them over the summer. I trust your guy's word. I also had a plastic fender on my old dirtbike that I repainted a couple years back and the paint held up really well. It was a special paint made for plastics, so i'll probably use the same kind. As for pictures, my phones camera isn't working currently, so I'll do my best to try to get some up through a camera. Went out today to start it up, and it started on the first pull. Think I found me a nice one.

Well maybe i jinxed myself and talked to early. Two days ago I took off the carb and intake to make a gasket for in-between where it was leaking. Did that, put silicon gasket sealer on both sides and put it all back together the way it came apart. was very excited to see if this would fix the leak and make this thing run perfect. Well its the complete opposite. It took a lot of pulls to finally get it started. When it did start, it would run good for about ten seconds then just die. It acted like it was running out of gas, when it has plenty in it. I decided to change the spark plug, it was very black and didn't look good. That helped a little the first time i started it up, but still after about twenty seconds of running at idle it stalls out and dies. It acts like the carb is filling up with gas initially, then burning that off and dyeing. We even changed the fuel line in between the tank and the carb, but this didn't help either. Tried messing with the adjustments on the carb, but still same problem persists. What else could be causing this? Before i put in the gasket, the petcock would not work very well, and it would continue to feed gas in to the carb even after it was shut off. The gas would run through the carb and leak out the drain line on the bottom of the bowl of the carb. It now barley does this. Any help would be greatly appreciated. I have no idea where to look next.

Don't get deterred grasshopper.

These machines are antiques now and what initially seems like a simple issue can quickly turn into a project as you have learned. Just have patience and start from the beginning.

Is the inside of the tank rusty? If so, is it clogging the screen on the petcock?

Have you cleaned the carb?

Have you checked the valve lash?

Is the choke working properly?

Just start from the beginning and work one problem at a time. You already know it has the potential to run well so you'll do OK once you go through it.

Inside of tank is really clean for being as old as it is. Took the line off of the petcock to the carb and it is getting gas down to the carb. We believe the float is sticking on the carb. Going to take it off tonight and clean the carb tomorrow.

Got the carb off today. Was pretty dirty. Let it soak in some carb cleaner for a while. Also pretty sure i found my problem. The float had a repair done on it at one point. It had some putty over what was probably a crack at one time. I looked at it closer and found another crack in it. Shook it, and sure enough gas was inside the float. So figure I'm going to need a rebuild kit, or just a new carb. Rebuild kit cost about 22 bucks on ebay and a new carb cost 30. Probably will go with the new carb. But, said why not and put some of the good ole trusty gasket sealer over the crack in the float. Let it dry up for about two hours and put it all back together and on the kaw. Put some gas in, adjusted the choke, pulled it once and it started right up. Ran like a champ. So I'm positive my problem is that float. I will eventually buy a new carb, but for now going to enjoy it while the sealer holds up. It was snowing here in ohio today, so got it out and did some donuts out in the yard. Glad i found the problem. One little thing I was wondering about though. When I started it after putting the carb back on I let it idle for a while and occasionally revved it a little. After I turned it off, and ran inside to grab some coats and gloves, i came back and there was a small, but still noticeable puddle of oil under it. It came from the breather hose that runs from the left side of the engine, just under the top end. What is causing oil to come out of the breather? Is my mixture wrong, or is this something to expect with an old three wheeler?

[fabiodriven]

It could be caused by blow-by or worn rings but if the machine doesn't smoke then that may not be the case.

Was it over-filled with oil maybe? Are you checking the oil level right?

I'm glad it was a simple fix for ya!

[78z2+2]

Thats what i was thinking, that it was over filled with oil. I actually don't know how to check the level. It has the little glass at the bottom of the crankcase like our four wheeler, but it doesn't look clear enough to see. Any other way to check it?

[muthey]

isn't there a dipstick that is attached to the oil plug cover?if not maybe pull the oil cap and put a flashlight over it to light up the crank case so you can see the oil level, I remember that my ninja was supposed to have the oil reaching the center of the sight glass when it was full. Either way couldn't hurt to change the oil as you don't know what was put into it before you bought it.

[78z2+2]

It doesn't have the dipstick. I will check it tomorrow using a flashlight. Thanks for the help

[78z2+2]

Just went out and checked quick. The entire sight glass was black with oil. There was a very small bubble at the top but i'd say it probably has too much oil in it. How do I drain the excess oil?

[fabiodriven]

Change it and fill it right. Find out if it has an oil filter. If it does, get a new one. If it has a screen, clean it.

Make sure you get the right viscosity oil and it is usable with a wet clutch. Motorcycle oil is what you want. I use synthetic, but you don't have to. Oil is not something to cheap out on. Expect to spend 6-10 bucks a quart, it's well worth it.

That should be the first thing you do when you buy a used machine, change the oil.

[78z2+2]

Alright, thanks for the help again! I'll try to get at that tomorrow...wish i didn't leave in two days, want more time to ride it.

It could be a dirty plug or you might have low compression
