New to this 2006 Burgman650 with only 3400 miles. Took it for a almost 100 mile ride yesterday and was really happy about all of the scooter. But I did not like was the sensitivity of the throttle and the engine brake. Is there some kind of adjustment for the throttle. Seem too loose or the return spring too strong. I don't like that. Can something be done or take it back to the Suzuki dealer and have him do something to it? What about the engine brake, That seems way too strong also. I'm not new to motorcyle riding by any means but this Burg is giving me a fit with those two problems. What do you all recomend?
