Hey Installed a big bore kit. on a gy6 139qmb. 50mm bore with 23mm intake, 20mm exhaust valves. Also installed 6.5 gram roller weights..

Installed it, turned it over and started after good 7-10 pulls. Left it on in idle for 10 min turned it off, turned it back on started right away and took it for a spin, did not full throttle it, went half way and got to about 30 mph where it started like spitting (wouldn't go any faster) I have a unrestricted cdi. Got it back to my house shut it off looked at everything again and try to turn it over.. nothing..

help please!

First things first, did you check for spark and if you have that then checking to see if you're getting fuel is next.
