After months of work, my CB500 is up and running.
Excited as I am about that, I still am nagged by some little problems. When I start the bike, after it warms up, I can open the choke completely, and it settles into an idle around 1150 rpm. last night, I took the bike out and got it up to about 40 mph in my neighborhood before the lack of plates gave me pause. Starting the bike today, I added four velocity stacks with small oiled foam elements. as soon as I did this, the bike bogged down and eventually stopped running. when I took the stacks off, the bike resumed its better running form, but still was backfiring every now and then, and the one and two pistons are putting out a little white smoke. I checked and the oil is not overfull, and the air/fuel screws are set per manual specs.
why would it run beter without air cleaners than with?
