1990 Yamaha DT200R advice

what broke now said:
I'd sure be interested in a diagnostic flow chart or sequence for 2t. I have an old 200exc that sometimes makes me go nuts, and it acts up halfway through the ride when i'm 20 miles out.
I say go for it.

We could put the full force of the DSBC brain trust on it but need a bit more info on the fault

I was getting 80 k.m./tankful, til reserve. That put me at 10l/100k.m.! <snip>

I have a service manual, but chose to ignore it. I never followed ALL of the steps outlined. I figured the float height really couldn't be out of spec., as I had never ever changed it! Somehow, it did change though. Though I looked at the needle and seat and found them to be o.k., I was getting desperate, so I spent $40.00 for a new one from Yamaha!(Never knew the "blow" test!) Got a spare now, anyway! I do appreciate every one who posted. Got me thinking, then acting. Cheers!

Glad to hear you got your bike going. For reference, my DT200 consistently gets 4.7 l/100km primarily city street riding. Last ride I rode about 150 km and it took about 7 litres to refill the tank. For an old two smoke with short final drive that's not too bad.

Too bad about the snow. Hopefully you have set yourself up for some good spring riding then. Don't neglect to do some winterizing otherwise all your hard work on the carb will be undone. You don't have to do much to have a big impact. Either drain your gas tank entirely and swish some oil in there or top up the tank and put some fuel stabilizer in there (I like Seafoam). Drain the fuel from the carb float bowl. Remove the spark plug and fog the engine with some oil (again Seafoam is your friend). Put your battery on a trickle charger to keep the plate from sulphating together. Doesn't take long to do these few basic things.

You can do some other things too. For example, at the end of your last while the bike is still hot, drain the crankcase and coolant and refill. No point having old oil sit in there all winter. Take the opportunity to clean your chain with some kerosene. Maybe I'm preaching to the choir and you already know these things.

I've had a terrible time trying to find a manual for these old bikes. You wouldn't happen to have a PDF version of the manual would you?

I have a photocopied manual for my 96 DT200 someplace.. It was displaced when moving. If I find it I'll let you know.

After sitting for a few months, with fuel stabilizer, drained carb and a full tank, I turned on the fuel valve and gas was streaming out the float bowl vent. So I pulled off the carb, checked and cleaned it. No longer floods but will not idle unless the cold start lever is left on. After looking at the above posted flow chart, I'll guess it is the Slow jet or air passage clogged or restricted. Any comments before I pull off the carb once again?

If someone needs a DT200R manual I'd need to send it to you as it is too big. P.M. me with an email address.

Hi there gt750. I would like to get a copy of the dt200 service manual. I can't find one anywhere. Would you be able to make a copy for me. I will gladly pay you for your time and materials. Thanks
