johnny87banshee Posted July 9, 2012 Report Share Posted July 9, 2012 my 87 is running but seem like a jetting problem , no tors , there holes in the air box lid , runs exellent on idle , but when im running its not like it suposed too. i went ridind and it was running like a champ no bogs always on the powerband when i needed it like a real banshee should run, until i realized i was running on the choke! take the choke off and it back fires once in a while when i let go the gas , and it dosent run really good . this is a jetting problem for sure? too lean? shee is stock im at 803ft of elevation , and temperature arounf here are between 20 - 30 degrees. what size of jet should i use and could it be somthing else?. i was riding with my buddy he has a 250sx three wheeler and i had it on 5th gear to follow him, i would need to regear the beast, what kinda gearing whould i use i mostly ride i the pits , and trails. i need more top end without loosing too much accelaration. thanks in advance Quote Link to comment Share on other sites More sharing options...
johnny87banshee Posted July 9, 2012 Author Report Share Posted July 9, 2012 stock gearing should be plenty... open up your carbs and make sure their spotless clean out the jets make sure your floats are within specs... make sure the slides open and close at the same time. if you got stock jetting but are running no airbox lid and have holes in the airbox id slap in a 220-240 main... alright bud will try it thanks!
