i just got a DR big bore kit for my 1982 honda urban express, and i installed it. but i have some questions seeing as i am a newbie here. do i need to upjet my carb? or change the carb? on the installation instructions it didn't say anything about upjetting or anything. in fact it recommended sticking with stock exhaust and carb/intake. i have only ridden the kit 3-4 miles since it was installed. but i wasn't sure why it would need to be upjetted, if it is possibly gonna cause a seize i want to wait for you guys to tell me whats up. thanks.
