I have opened the high speed needle from 1 7/8 to 2 and then 2 1/4, then 2 1/2 then 2 3/4 and 3.....the low speed needle was even leaned out to 1 1/4....It seemed like the more I messed with it the half throttle area it won't transition right when the valve opens up for half or full throttle..

The idle speed was perfect no problems at all, its just the half throttle and full throttle area is where the problem lies...This is where I tried to tune it for 3 hours with no luck...I think I started from 7am until 11am then from there I gave up and just packed it up and sent it back to DA for engine service describing the problem above.

I also called DA before I decided to pack it up and they said clean the carb with carb cleaner which I did and that didn't do anything to the problem.

I was just originally curious if something like this happened to anyone or does it sound like the engine still needed to be broken in some more? Any thoughts?
