Running rich?
Posted: Mon Jan 18, 2016 12:15 pm
My bike seem to have very rich smelling exhaust, especially when i start it cold and let it idle few minutes. Few guys that i ride with also told me that riding behind me my bike smells very rich.
Everything is stock, jets, paper filter, spark plugs look grayish white which i think means lean. Bike starts easily when cold as long as fuel bowls are full.
I do not have high idle when choke is applied as i adjusted the choke idle level fork on the carb wrong. Bike runs fine, no issues what so ever other than that rich exhaust smell.
Originally when i cleaned carbs i had fuel mixture screws out at 1 1/4 but when i did a valve adjustment i opened them to 2 turns out and i did not have that rich smell.
Another thing that i noticed is that after a ride break, i need to twist a throttle few times for bike to start when before with 1 1/4 turn out, bike would start with just a push of a button. Second thing is that before that change, bike could of gone a full week before i needed to blow into the vacuum line to fill the fuel bowls, now only few days.
I'm do for a valve adjustment and i'm planning on doing that beginning of next month and i could pull the carbs out again at the same time and check on things only not sure what exactly.
