Seemed to be fine..but went for a blast this morning and when getting to higher revs seems to be holding back a bit and seems a bit choked up after about 40 mph up until then very smooth and responsive.and starts first kick every time..warm or cold...?
Anyone any ideas on jetting maybe main up a bit.

Pull the choke on when it holds back and see if it helps. If it does then the main needs to increase.

If the choke don't change the situation (ll say that a bigger jet is needed), try to change the needle
I have read that a D29 needle + AQ 268 are recommanded ....
