possible jetting issue

[sheeapet]

I just installed a new piston 20 over in my blaster, I am trying to break it in! but for some reason as soon as shift to fourth it bogs. but let off the throttle and ease into it the speed gradually increases. I was thinking jetting or air leak any advice would be appreciated. "o" almost forgot the only mods are fmf pipe, v3 reeds, tors eliminator kit. Thanks in advance:-D

it sounds like a jetting issue but im not completely sure

I have another blaster and a banshee and never seemed to have a problem with loss of top end. I,m thinking maybe the main is off.

happened to mine, main jet was incorrect

Excellent, Just wanted a second opinion before i start assuming the worst.
