Hi all, 
I'm Al from Southport,  had my 03 fazer for about 2 months and loving every minute,,,  I Need some advice please.. I've put a delkevic system on the bike but now I've noticed a flat spot between 1 - 2k revs,  almost as if it's struggling with the power then it will kick in,  also in low gear/slow riding in traffic it jerks and splutters.    Will I have to purchase a dyno jet kit or power commander to solve this issue.
Thanks in advance for anyone who can help.....

Have you just fitted an end can or have you changed the entire system and removed the exup valve ?
