low spark on spark plugs

[ICEG]

well my katana was working fine when it started having idle issues (the choke spring was bad so i changed it )
after a while she seemed to run fine then one afternoon i tried to start her up all i heard was the motor turning over
so i checked the tank for fuel it was good since i have clear fuel lines i saw that the fuel was goinfg to the carbs
i then preceaded to check the spark plugs

the looked like crap so i went to a local motorcycle shop and got the oem spark plugs (22.33) for four of them here in canada
when i put them in and put the spark plug cables on and the tank on top all conected nicely i preceaded to charge the battery
next day i tried to start her up she wouldnt.


my guess was the spark plugs/the coils even though i havent tested the coils


im just looking for some imput from KR

Coils and wires are an easy fix, but probably not necessary... Can you pull a plug and see if you're getting any spark (better if you have a decent meter, but whatever you got).

I'd guess is it's more than likely a carb issue.

well i pulled out the sparkplugs and they have a week spark
but i dont know what could be wrong with the carbs

[arsenic]

how do you know it's a "weak" spark? I would try new plugs long before I EVER thought about the coils. If you are getting spark, the coils are working.

[ICEG]

i have new sparkplugs installed
i had one out of the block to inspect the spark as i turned the bike over a couple of times

[arsenic]

did you check the gap?

[ICEG]

yes its .65mm

[arsenic]

ok, good, now did you check the signal generator ohm resistance?

[ICEG]

no i dont know where it is
and what is the resistance that should be there

[arsenic]

crap, I gotta look stuff up, I'll post it later.

[elkat]

If you are getting spark, it is most likely dirty carbs. When was the last time they were cleaned? I know when my bike starts running like crap, a carb cleaning is in my future.

[ICEG]

well they havent beeen cleaned in a while but they shure look as if they are clean

ill look into it elcat

im surprised that arsenic doesnt know it off by hard
some times i wonder if he has a day job or does he just fiddle with his kat lol

[arsenic]

no, I don't have a day job, all I do is mess with the kat. I got hurt in a motorcycle accident in 05. I own a small business parting out bike on ebay, by small I mean just me So yeah, all day is spent around motorcycles
