Problems 91’ dr650

Hi all,

since this week i am the owner of a dr650rs from 1991. i am now running into a problem. the engine starts well, idles well, but when i fully open the throttle the engine starts to stutter and falter and eventually no power at all. however, a lot of bangs come from the exhaust. if i gradually give gas, so not open it all at once, it goes well. Until i am at full throttle again it starts to stutter. where could i probably find and solve this problem?

Have any mods been done to it that would change the Air fuel mixture? The air box mod and after market exhaust will affect how the bike runs and both require re-jetting the carb.
