Hey guys
This question is for my kids Z250 but I am confident in the advice I recieve from this forum. After our last trip to Oregon I returned and re-jetted back to the jet we always used at our altitude. But since we've got back my son's quad just cuts out momentarily at high revs in 2nd and 3rd gear usually. It only seems to occur at full throttle and at high revs. I have cleaned the carb, double checked the jetting, changed plugs. I am stumped...any ideas?
Thanx

 

my ds did the same thing try a new battie or charge the battie

 

sounds like you need to go one size down on your main jet.
