can i use another coil?

a friend of mine who used to race fj's 1000

says he has some coils he didnt use

and he is gonna give'em to me!

he says they are special race coils

would there be aproblem to put'em in my seca?

i wanna try them to see if it starts better. :!:

 

Got to make sure they have the same primary resistance as your original system or they may not fire or cause your TCI unit heartburn. Check spec's on your original and ohm out the new ones. If primary and secondary tolerances are the same, your in luck! Happy hunting and where can I find nice friends like yours?

 

ye thats what i was afraid of!!

frying my cdi!! :!:

anybody know the ohmnage of our coils?

ok i'll check'em out and tell u'all!!

 

At work right now, I'll post them when I get home.

 

the Yamaha manual for a xj650g states primary coil resistance at 2.5 ohms +/- 10% @ 20 C ( 68 F ) and the secondary coil resistance at 11k ohm +/- 20% @ 20 C ( 68 F )

 

Most replacements (Accel / Dyna) have the resistance for our bikes as 3 ohm, secondary somewhere around 11k ohm. Many have done the swap - no problems with the TCI / CDI

 

Thanks guys. Always nice to have a group consensus. Do your new coils meet these requirements xj650rjseca? Hope so! Check out your old ones too, they might be salvageable as well. Check the other links for tips on this possibility. Good luck to you!

 

hmm my "old" coils are fine

i mean the bike runs fine!

but im curious if the new ones would help

hoping it will satrt better in the mornings

i'll let u all know when i get'em!

 

hmm one more thing!!

which is the one before the spark plugs

the primary or the secondary?

 

xj650rjseca, primary means first or in this case the 12 volt side, and secondary is the high voltage going to the spark plugs.

By the way did you check back at the postings you were inquiring on your avitar? I've left a couple of choices there for you!

 

Do you have a USA spec bike? Believe me, they start a LOT easier when you can turn off the headlight, which a lot of US bikes wont let you do w/o a simple mod.....

 

thx for the pic nick!

and yes its the usa version,

i'll check into that light thing.
