Rebuilt the caps.

Should I bother replacing the wires on the 99 Bandit coils that I'm waiting to receive? Also, what does rebuilding the caps entail, and more specifically, uh.. what are caps? :oops: :?
 
As long as the wires are long enough to reach don't bother switching wires. Just cut them to length if they need shortening. The caps are the piece at the end of the plug wire that fits on the plug. The ones that come with the coils should be in good enough condition. If you have to shorten any wires be careful and just cut through the very outer layer of wire insulation. It's only about 1/16" thick. The plug caps thread on and off the wires. A little oil on the rubber seal on the caps makes them slide on and off the wires easier.
 
Went out to the wrecker to find some newer coils. He's got a set of '86 GSXR1100 coils coming in in about 3 weeks. I think I just may pick them up, along with the bike they're attached to. :twisted:

Put in the new plugs later that afternoon, and it's running fine. When I tested the resistance on the testy coil (1&4) it came up with 4.5 ohms on the low end, and 35,000 on the high side. Within specs, after a little cleaning of wires and the contacts. The bike just doesn't like a hotter plug, which only one dealer insisted was the plug for mine - DR8ES (UK plug) I put in the US plugs (D9EA) and it's purring like an angry cat.

Found out something interesting.

I found out something interesting. It seems 'if you can find them' you can get coils for old GS bikes that are dealer recomended replacements that come with wires long enough to fit our bikes.

You'll never guess what they are.

The same exact coils you can get off the GSX-r, Bandit, and katana.

Just one more good reason to take Mr Ricks idea and get some for your bike.
 
The more coil you have, the more power you'll have.

I hate to get technical here, but, transformers either amplify voltage or current, not power. The power remains the same - actually decreases due to losses that are unpreventable.

Ok, maybe that's too technical, but I hope it makes sense.
 
Does anyone know how many volts a stock GS coil produces compared to a late model Bandit coil?
I thought I read a new stock coil was like 10,000 volts (when new), so what about newer coils off a Bandit or Katana?
 
most factory coils are set around 10k-15k. the aftermarket can supply more since thats what they specialise in.
 
I've just purchased my first bike, a 1981 GS 450L. Cost me $170 and all that it has wrong with it is a bad front brake master cylinder, broken ignition lock that works with a screwdriver, and one of the coils drops when hot.

Please forgive my ignorance, as my mechanical knowledge is fledgling (actually one of the reasons I bought the bike, so I can learn,) but what coil should I look for that would be applicable for my bike?

Thanks,
Mike
