JUST GOT A BLASTER AND I HAD TO PLAY WITH THE THROTTLE TO GET THE RPM UP BUT THEN IT WENT FINE. ABOUT 10 MINUTES OF RIDING IT BOGGED OUT COMPLETELY. IT STARTS FINE AND IDLES FINE, BUT BOGGS WHEN I GIVE IT GAS. iT WILL SOMETIMES GO GOOD FOR A COUPLE MINUTES THEN BOGG AGAIN. SO FAR IVE -PUT NEW REEDS IN, -STRIPPED THE CARB AND CLEANED IT ALL, -REPLACED THE NEEDLE VALVE, -REPLACED SPARK PLUG, -CHECKED IF THE OILER WASN'T WORKING PROPERLY, -LOOKED OVER THE WIRES, -CHECKED THE FUEL FILTER AND AIR FILTER, -EXHAUST ISN'T CLOGGED........................IF ANYBODY HAS SEEN THIS PROBLEM BEFORE PLEASE HELP ME

 

Check and make sure your throttle cable isnt getting pinched somewhere. Also mess with your idle and it might be your pilot jet, it should be 1-2 turns out if its stock.
Done a compression test lately?
List your mods.
Welcome to the forums.

 

Yeah do a compression check, or even better a leak down test. You could have a leak. The base gasket on my blaster blew out. It would run good for awhile. then would run erratic.

 

By leak test he means let it warm up then while its idleing spraay the outside of the carb with carb cleaner, if it revs up you have an air leak somewhere, and need to replace your carb gasket more than likely.
