as far as carburetion don't ask for help if you are running pods
That's great!
I'm not running pods, just the K&N style filters. Does that picture of the spark plugs give any indication of what's going on?

Well I've been having a hard time keeping the idle even, it gets kinda eratic when it wants to.. what do you mean by "run plug chop"?
Joey
as far as the idle is your ignition all tuned up ?
plug readings are only really gonna tell you jetting is correct at high throttle run preferably wide open for at least a couple hundred yards on a hot engine then you kill the motor quick clutch in preferably rolling up to a place, take yer time,you can pull a wrench out and check the plug for a reading, thats a plug chop
once you let the motor idle it will get darker sometimes just plain black

No I am waiting on a new set of points to come in, and then I'm going to set the timing with the timing light I have.I wanted to make sure I did that first before I upgrade.
Is the electronic ignition worth getting on these bikes? I do that on all my aircooled VW's because its a worthy upgrade.
well i had the pamco and it worked, until it didn't ???left me stranded...i sent it in for repair a year ago no word back :-[
.i switched back to points(get nos honda well worth the $40+ they cost,do not get cheep china points )
new points set correctly work great and you don't need to touch them for thousands of miles

Ok awesome I'll stick with them then. Like I said I really want to get the bike running smoothly then I will tear down and redo the bike right!

Any one had a good reliable video for adjusting points and timing?

Hahaha no I got that down! If the CB had a distributor I'd be all set on it too! I like to make sure I completely understand how to do stuff before I dive in :-[crazypj said:
if the bike runs now,do not mess with the backing plate position and or mark where it is
swap out the points, gap them at .014" there is a tiny hash mark on the points cam where to set the points
then as long as the bike will start up,and run, hook up the timing light number 1 left
set full advance(run engine up to 3500 rpm when doing so) between the marks by moving points backing late
then hook up timing light to number 2 right cylinder and check full advance if it is off it is changed by adjusting points gap a bit,wider gap advances smaller gap retards
when swapping out points it is pointless and a waste of time to set static timing, just move on to the full advance setting,this is givin that the advancer works smoothly and has spring tension to smoothly return

Hello again! Got the bike fired up and running ok. When I hook up the timing light to 1 "LF & LT" is right at the top. Is that right? Or should " F&T" be at top?
Thanks,
Joey

Very true I will look into it more the idle surges big time going from 1500-4000 sometimes lolxb33bsa said:
