It lives on a metal tab on the left side of the battery box. The tab is at about a 45 deg angle toward the rear. It's squeezed in between the battery box and the frame. Dunno how you're got routed to the right side of the bike.


thanks Ladder! my battery box doesn't have that 45 deg tab (instead it's a vertical one under the rectifier) but at least now I know where it's supposed to go :tup:

I sandblasted all the rust off the battery box and have been repainting it:

I opted for "suzuki orange" because

(1) I have never liked the fact that bikes are usually just a hot mess of black paint & grime in the one place where being able to see small bits clearly counts

(2) eventually I'll return the bike to it's original white & orange - except with a white frame

(3) the paint was on sale :lol:

Did you buy enough paint to do the whole bike ?

when it comes time to strip and do the frame, I'll probably opt for powdercoat. I'm thinking white frame, orange engine & swingarm, white tank & oem orange beak.

as far as the wiring harness goes, have any of you ever built a new one from scratch, maybe just re-using the specialty connectors? I'm wondering how much voltage drop and increased liklihod of breakage I'm having from the 26 year old OEM harness. If I'm going to strip the bike down to the frame (next year...maybe) then I'd just as soon rebuuild it with all new wiring, or at least as much new wiring as possible.

I think the harness would be quite easy to reproduce as there is not much to it. The hardest part is sourcing all the correct terminals to fit the connectors.

White frame sounds good mate :tup:

The new Shorai battery (finally) arrived yesterday and here it is, ensconced in the sandblasted & repainted battery well:

The various wiring bits are attached where they are supposed to be and presto: still won't start!

The starter is going strong - so the new battery is doing what it should. I am noticing a distinct lack of fuel odour during my efforts, so perhaps it's the pump? Yes, tried the cock on both 'reserve' and 'on' and there is plenty of fuel aboard.




I can also now eliminate yelling "Start, Damn you!" as a solution...

Have you connected the vacuum pipe from pump to carbs?

hmmm...I never disconnected it, if that helps narrow things down :lol:

dropped the bike off with the mechanic today, so we shall see what he comes up with. There was definitely no spark, so I'm hoping it's a dead plug, broken plug wire or some other relatively minor issue 8-)

there's good news and bad news...


the good news is that the 26 year old wiring harness is fine



the bad news is that everything the wiring harness connects to is not :lol:





through the process of elimination, the mechanic isolated the ignition (inner contacts are loose from wear), the kill switch (corroded and now bypassed), the side-stand switch (corroded and also now bypassed) and ended up still unable to get a spark

Through additional testing, he found 2 components that are out of spec:

the charge coil within the stator

and the CDI

Which leads me to ask you guys the following:

1. Is this series of failures familiar to any of you?

2. is it likely a cascade failure due to one particular component?

3. can anyone confirm if the stator charge coil off the 1990-1995 DR650 is comparable?
