my 1987 TW200 is running perfect, but once at 60 she just turns off..... i am not sure how to adjust the carb and need help. Could it be anything else?

CDI?

I have a similar problem. I have changed the cdi and it didn't fix it. tested all the electrical with an ohm meter and found the stator coil to be way out of spec. Waiting for those parts. If that isn't it i am at a loss.

Can you let me know if that fixes the problem ? my E-mail is [email protected]

I had the same problem, see this thread:

Took two cleans to get the carb all good.



Reilly, read the carb cleaning sticky at the top of the page; it will help you.

I'm dealing with the same problem on my xt200...haven't been able to really ride it for years. It starts on the first kick, but after you let it warm up, It just cuts out and dies when you get into the upper revs. It won't restart until it cools and sits. I just put a brand new chinese carb on, but it does the exact same thing with the well cleaned TK on there as well. I think it's the CDI, so I'm trying that next, but I have the feeling it could be a bad pulsar coil, or even the main harness. I already swapped the ignition coil so I know it's not carb or coil. I'm thinking either CDI or the stator section at this point. Only dies when it fully heated up.

As I've been messing around with Ham Radio for some time now....If you think it's a thermal problem (when it gets hot) you can pinpoint items with circut board freeze spray or something like it. It will allow you to almost make parts "fail at will" if the parts problems are heat related. I've even made makeshift cold rooms and hit them with a tank of Co2 to prove out the problems. In a pinch a zip-loc with ice may get you by. OM

I know this is a long shot, but I've seen this happen on other engines. Have you checked your valve clearance? If it is out of spec, it can cause the engine to quit altogether when up to temp.



The next thing to do is to get a good spark tester, and watch how it behaves when things go wrong. It's a useful tool for more than just your bike(s).



I know your thinking "Valves? Really??" But it is a cheap & easy thing to eliminate from the list.



My two cents. I know the '87s are plagued with electronics problems, ouch! m.
