air leak somewhere in the rubber manifolds would be my guess...




i wish i had a pic of the old rd400, was kindof a rat bike, we called it the pickle... bet you can't guess why.   ;D
btw, rat bike doesn't mean it wasn't a screamer!!!

I found a place that has a few old rd's laying around.  From a 250 to a 79 DS.  Dont know how to deal with them and the bike as I am still trying to get a 650 from them.

You could have any one of several problems. Just a rich RD wont idle sometimes.

If you've done carb work there is a major pitfall many RD owners run into. This happened to me with pretty much the same issue your having. It involves your float bowls. Look at the float bowls. They look pretty much alike, but with very close inpection you will find they are not alike. One has a hole that the other doesn't have. If the bowls are reversed you will have problems. Now it's been a long time since I dealt with this, so I'm going from very old memory. So I may not even remember the details exactly.

On the bottom of you carbs, you have a long tube. When you put on the float bowls this long tube goes into the round hole in the float bowl. Look at each float bowl very very close. At the base of the float bowl where the tube goes. Look at the bottom. You will find one float bowl has a hole and one doesn't. Get these bowls reversed and in the wrong place and you got grief.

Thanks for  the heads up.I am a member of the U.S.A strokers forum.But just wanted another view or thought on my problem.I have checked the carb manifolds,they seem ok,i have another set i think i will swap with.I will also check the float deal mentions,Not sure on that thou cause even with the other carbs it did the same thing? All is stock except uni open end filters.

how rare are these bikes?  What about parts availability, etc?  I am loving the idea of having a two-stroke for whizzing around town.  are they rare or fairly common? 

I HATE to threadjack here...
