running on 1 and 4

Switch the orange and gray primary wires at the coils and see if the spark stays with the orange and gray or with the coils.

RB i did switch wires, got spark on both coils.

thanks

ok took bottom of air box off filter a little dirt.
what i did find was gas in box, not alot it was wet on the sides.
will have to get new filter.

Hey again,

Okay, if you have FUEL in the airbox, then you have at least one carb float valve that isn't working and allowing the carb to flood, and possibly not just back into the airbox, but also possibly forward into the intake boot, into the head, past an open valve and down into the cylinders, then past the rings and into the OIL. You need to check your oi level and be sure it's not contaminated with FUEL.

Next, like you said, probably time to do a rebuild/THOROUGH cleaning of the carbs, that should fix the leaky float valve, and then you won't be flooding the engine trying to start it.

Don't try taking the circuit board OUT OF THE TCI BOX, just look closely at the pins and their solder joints to the board.

Going back to your early comments, you said you have spark on 1-4 coil, but not the 2-3. THen you swapped the harness coil connector wires, GRAY for ORANGE, and then you had spark on 2-3, but you possibly forgot to mention that you did or did NOT have spark on the now swapped 1-4 coil. Probably not, because if you didn't have spark on 2-3 coil UNTIL you swapped the harness wires, then the coils are NOT getting the trigger signals to fire.

That comes from both the PICKUP COILS, but the PU coils trigger the TCI, so you could still have problems with either PU coil or TCI.

As was stated the LOW OHMs of the 1 PU coil may be diagnostic of failure on that coil, and so should probably start there with replacing it. Keep at it.

TC, isn't high ohms the sign that a pickup coil has a faulty wire? (Not trying to get into a fist fight with an expert! :-D )

Normally, a fracture of the internal epoxy filler causes a short internally of the coil.....which results in a DROP of ohms of several tenths. For example, I've had the stock 3ohm coils showing partial failure at 2.4 and 2.6ohms, which I replaced with Honda VFR 1100 coils which checked out at 3ohms. These coils are also plug-n-play. Also resulted with bike running like it did when new.

Low ohms is a sign of a short in the pickup coil itself. Low ohms creates a very weak signal to the TCI.

[skids]

That make sense for a short to ground. I had a pickup wire that I knew was bad because it was stretchy in a spot yet there was no break in the insulation. So, I guess that is a possibility as well. I don’t know what is more common.

yes did not finish test went back pulled #3 wire off put new spark plug in ground on head and no spark then pulled #4 cap and ground plug got spark.
so the coils are good.
but still no spark on 2-3

will check oil will change before i start the bike

so trying to get carbs off.

looking for pick ups and black box.

thanks everybody for all this help

[earl G]

so far I got the carbs off bike. been cleaning outside of them. order parts coil pick-ups and black box tci. clean air box. looking at wire connectors, take a part and clean. to hot here so only work on the bike a little.

so waiting for parts
a break in the heat Saturday so will take carbs apart to clean

[earl G]

update

I got new used parts, pick up coils and black box. installed pick up coils.
still no spark on 2/3. so install new black box .and have spark on all four.

[earl G]

test test test

[earl G]

try to clean carbs could not get apart. so clean outside body. put new fuel lines and filter on. it cranked two times started right up.

[earl G]

changed oil and filter,checked for leaks, none
went for a ride, a short ride, pulled over to look bike over no head light or speedo,tach light.

[earl G]

ride back home. have a beer or two and think about it.
must have missed a connector by the coils.
so take it back apart.
