Already think i know the answer, just after a second opinion to confirm, or point out how wrong i am, either works. I recently bought a Cbf 600 which is carb restricted. As far as i'm aware these restrict the air that is added to the fuel mixture, this is causing the bike to run rich (as the carbon deposits on the exhaust show) and i believe also causing issues with starting when the bike is cold (auto choke adds more fuel so therefore needs more air) Planning on having the carbs balanced soon as possible, but is it worth it or would it make no difference with it being restricted?
shouldnt see why a restrictor would cause such issue as the restrictor is 1 after all the fuel and air mix or number 2 a throttle restrictor which just restricts throttle,
The way i had it explained to me was that the carb washer/rubber bung restricted the amount of air, to me that explains it running rough when cold, and running too rich......
the way i see it it doesnt exactly work like that cnt remeber exactly sure im wrong in explanation but yor intake valve is restricted it doesnt effect the air/fuel mix maybe they didnt connect properly or knocked something causing a vacum leak or something like that
I may have been informed incorrectly then, i was under the impression it just restricted airflow :thumbsup:
if you restrict the inlet tract then you limit the volume of air the engine will pull in and therefore less fuel.
