HI, so i had moved out to CA and left my Ruckus in AZ untill about 2weeks ago when i went to go get it, was sitting for about a year, but with a shot of starting fluid she started right up! and ran awesome so i brought her back with me to CA. before her maiden CA drive i cleaned it up and charged the battery with a car charger n still she started right up (now with a charged bat even better!) ran n drove awesome drove all around town parked it got back on started going up a hill n BAM started having problems... it was as if i let off the gas for a second then ried it again... it started off not so bad but has gotten worse!! IT DOESN'T DIE AND STILL STARTS RIGHT UP, idols awesome even when i rev it it sounds perfect takes off strong but every time now under load maybe around 8-10mph it just starts acting like i release the gas n get back on... almost as if its cutting out fr a second or misfiring but more like just bogging down.... I have already done usual stuff... first thing i did was clean out the carb real good... (didn't help) after alot of google search i thought i found the problem and i ordered a Chinese fuel pump made for the ruckus, and STILL its doing the same thing!! I have no idea what it could be! i need help! is my ruckus dead?? I dont have enough money to buy new parts that arnt the problem im so sad i wasted $15 on that new pump oh PS i did also already do the throttle reset where u short the wire to bat... didnt help..

 

ok so i got a new fuel pump just in case the one i got was bad... no luck... then i cleaned the carb out for the 3rd time just to make sure... still doin it... i dont see any messed up wires or anything. i even byassed the fuel filter and valve to see...how can i check if the ecu is the problem without spending $350? also if i just got a NCY CDI would that byppass the ecu fuel control??

 

clean the jets and carb. jumpstart it by hooking up to car if battery is dead. dont start the car

 

I’m having the exact same issues, did you ever get this resolved? Thanks
