I have been restorying a 1973 Yamaha rd250 but am having trouble with the hoses to the carberator. there are two exit ports that i don't know where they connect. One is at mid level of the throttle body and the other is from the bowl. This is the last step before i crank it over!...can't wait.
Any light you can shine on this or photos would be appreciated.
