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
