Bought a rat ds a while back and finnally have some time to get it sorted out. Has some type of mikuni flatslide carb in it. Jetted way fat. Had a 280 main from the start and was fouling plugs like mad. Dropped it to 250 and it made it better but still not right. Other posts ive read with those using mikunis are below 200.

Hope you can see the photos without registering. Couldnt figure out how to post photos here.
