on my gs750 the 1-4 point is sparking. i know it is a bad condensor. question is: will this cause my problem with my full throttle bogging? i am 2 inches from parting this f/in bike out.

Possibly..but the main issue is the points sparking.. They will spark very faintly normally..but its kinda hard to notice. If your seeing a good big spark, then the main problem is burnt points and the gaps being WAY to big. Look at the flats on the points and i think you may see lots of pitting and maybe abit of a blackish color. Time for new points i think..I always replace the condensers too just to be sure everything is fresh. Properly gap the new points and while the cover is off check the timing as well.

Sparkey if you are going to get new points and condensers make sure you get the correct ones as there are two different types.
Kokusan and NipponDensi.
You need to get the points and condensers to suit your base plate. The contact points are not interchangeable. Also the advance/retard unit is a match with the base plate and contact points.
Don't mix and match.
KOKUSAN Contact points (above), note they are larger than the ND point set.
ND points set above are smaller than the KOKUSAN (top picture).

The 1-4 point is sparkin like a giant sparkplug. hopefully this is what the problem is. seriously thinking about the dyna ignition. the bike was running better but not perfect untill I opened the stator up and adjusted the points. gonna try to close them up a little while waitin for parts. It is timed correcly and advances as it should.
Thanks guys...
Thanks guys...
The gap should be .018 inches...no more. I usually shoot for .016
yep if the points are sparkin' the plugs a sure aint.
electricity follows the path of least resistance - and if the lazy little spark bugger can find a path back to ground waaaaaay before having to travel all the way up to the top of the engine and thru a resistor cap well it's just going to avoid the whole trip and just sit and spark his butt off down at the points plate and burn up the contacts.
bummer for igniting fuel in a pressurized chamber.
get a condenser. however from what I'm reading , I advise getting 2 new sets of points and 2 new condensers , and a set of NGK spark plugs.
, by the time you get a condenser you'll need points. and then hope the plugs are not fouled too badly. In my experience, try to patch up a points ignition system 1 part at a time--you'll have persistant problems.
you'll get it running again - setting points is an art. keep fiddling with gap and backing plate alignment.(0.12"~0.16") gap is a big window for timed igniton to be off. A timing light is handy to get perfect dwell for both pairs of cylinders.... as is a dwell meter. - but who has those anymore?
I like 0.014- maybe 15 in a pinch when all I have is a match book or business card, but the range is 0.012 ~ 0.016 and adjust the backing plate accordingly to your choice of gap.
I like dyna "S" easy simple clean and last for years.

Gapped the points today for .014 and timed it with a timing light. I have a cheapo set of feeler gauges from the ZONE, i have my doubts on how accurate they are. .018 was way to much gap. WOW!!! What a difference. No wonder all that carb adjusting wasnt having any effect! It now is ridable!! Cant wait to see what a new set of points and condensers do!!! I am gonna keep it stock and go with points and skip the dyna s setup.
Thank You Chuck, Don, and Trippivot!!!!

I was thinking .018 for some reason..but hey i havent been right for a long time so that doesnt surprise me..LOL. Glad its running better. Once the new points and condensers are in the carbs will be way easier to get set up. Good hot and consistant spark goes a long way.

You were right! The book says .018. I think its maybe the cheapo feelers i got or the points are so worn that 018 is too much.
PS: i aint right either so join the club:lol:
