Xj650 maxim help please

hi everyone I have a xj650 which I believe is a maxim ? Well the igniter cdi has packed up ,no spark, but I'm really unsure which bike it is as it's now a trike, no frame numbers as these are from donner car , anyway the igniter as 2 plug ins . 4 pins in each . I have another cdi but that is possibly of a seca engine (don't know if either spelled correctly lol ) this as 5 pins in left plug and 4in the other, when plugged in it will start engine but sounds lumpy and not happy to rev. So can it be a case of moveing the wires to make it work .

 

What serial number is on the motor and what numbers on CDI boxes

what year xj 650 motor? is it a yics motor or non yics this will make a big differance for the TCI box

you need to use the proper pickup coils with the proper TCI box. because of the harness.

 

look at motor shorty vin

When there's no spark, first test the coils, then the plug caps, then the plugs. While TCI failure is a possibility, it's uncommon.

 

On the igniter it as type tid 14-02. 4-17-10 and in a silver bit it as 004 . I have had it running on this but had a loose connection and wile trying to fined it with ingnition on . And hasn't fire on this one since , has I said I have another one but think is of s seca.havent got the numbers of that one but it does fire and start on it . That why I think iv blown the original one .

 

which type motor do you have ? the wiring harness from the pick up coils is different on the ycis version as compared to the non ycis and the tci will not swap.

tdi 14-02 4H7-10 1981 xj650 should have 4 tabs in each port

 

Note up garage till Saturday will get it then being thick what do you mean by 4tabs .?

 

would be the equilivant of the male quick disconnect. flat blade that slips into the connector.
as Kmoe suggested you should ohm out your Ignition coils and pick up coils as well as the spark plug caps to make sure they are in spec.


see the flat "tab"

 

checked and all ok there.

 

have egn no now 5v2-000959 and correct ignitor no tid 14-02 4h7-10.

 

motor is from
1982 XJ650 Seca USA : 5V2

your ignnitor is from an 81 .

can you discribe the wires and how they are in the connector from the pickup coils that plug into the connector of the tci

the wiring diagram shows a 6 position connector with with 2 black wires in position 1 and 4 then orange and gray wires in position 2 and 5 for a 1981 tci unit and pickup coils.

what are the numbers on your other tci unit?

 

the numbers on ic ignitor = tid 14-08 5v2-10 .and wires go 6pin side from left 1 blank 2 orange 3 black . Bottom row from left 1 black with white 2 grey with blue . empty but there is a connection in there. and 4 pin connector on right of tid top 1 red/white 2 orange.bottom left 1 black 2 grey.

 

the wiring you discribe indicates that your harness is from an 1982
your motor is an 82 xj650 rj Seca

you want to use the tid 14-08 5v2-10 unit with it
the other tci unit is wired differently

to recap you made a trike from an 82 seca motor what did you use to wire it up, original harness?

what do you know about the motor history?
are you using yamaha oem ignition coils ?

 

NO i didn't build myself i bought it as is. [ project ] and can't ask last owner [ hes past on ] dont really no much as never had a none running yam before .this trike was in bits but nr completed now . as i said it was running and sounding great using tid 14-02 4h7-10 .this no longer works at all . but really hard to start and runs terrible with tid 14-08 5v2-10 .

 

ok then what we do know is that you have an 82 seca 650 motor which has to use the tci for an 82 seca because of how the tci is wired to the pick up coils.

you have to treat this as a new to you non runner.
IS YOUR MOTOR AN YICS OR NOT???????????

have the carbs been cleaned?
valves checked and inspec?
is the charging system working properly?
battery age?

look at the ignition coils see if you can ID them and ohm them out and the plug caps (the caps unscrew)
ohm out your pickup coils as well.

1982 XJ650RJ Seca (non-yics engines): 700 ohms +/- 20% = 560 ohms to 840 ohms acceptable range
1982 XJ650RJC Seca (yics engine): 650 ohms +/- 20% = 520 ohms to 780 ohms acceptable range


Ignition Coils:

Primary side (input from main wiring harness):
2.5 ohms +/- 10% = 2.25 ohms - 2.75 ohms acceptable range

Secondary side (spark plug wires, without their end caps):
11K ohms +/- 20% = 8,800 ohms - 13,200 ohms acceptable range


Spark plug caps:
5K +/- 20% = 4,000 to 6,000 ohms per cap acceptable range

Spark plugs:
0 ohms per plug

 

its not the yics as does not have the extra port as per picture earlier post . and thank you guys for all your help .

 

Using the wrong TCI will allow the bike to idle, but the ignition advance is different and will make it run like crap otherwise.
My vote is to ship the tid 14-02 4h7-10 off to a member for testing (to confirm that it is faulty), and then expect that you'll need to either have it repaired or replaced.

All of the N.A. 650 Secas were non YICS. If the trike were built from parts (likely) then it's entirely possible that the TCI and wiring harness are from a non-YICS Maxim. That combination would allow the engine to run well.

 

This is incorrect k-moe. In Canada we got both, non YICS are silver, YICS are red with electronic tach and oil cooler. What you said I think maybe true for the US.

 

Oh Canada, our home and native land.
We got better bikes, directly from Japan!

Is that Cornwall, Ontario, @Pdross ? I'm within spitting distance of the st Lawrence.

 

Not so much anymore, Canada adopted the US DOT emission standards for motorcycles since about 99 I think.

 

Yes I have owned both, had a new silver one back in 82 and have a red one now.

 

no m8 cornwall uk cold and wet , but when the suns out you can't beat it .

 

Like cornwall ontario, only we're cold and icy. But when the sun is shining... and closer to our hemisphere.

 

So had another look today used the tid from the seca 14-08sv2-10 , it will fire up after a while but its not happy . it will tick over when warm but won't rev at all, sounds like timing well out . tried again with other tid 14-02 4h7-10 = turns over the same but , no spark .

 

Been back up garage today , put the tid back on 14-02 4h7 - 10 . Cleaned a few connections . And she fired up and sounds sweet . But if it's a seca why is it running on a tid for a maxim. The wires are a mess with open ends everywhere.

 

Pics pls, we like to see messes go through the process of becoming nice.

 

Get some close ups latter's .ha ha

 

The only difference between the two is the advance curve. If you have the wires all hooked up correctly it'll run at idle fine.

 

Runs fine at all revs k-moe , got to sort out a tank now but hopefully she stays running . Got loads to do to the rest of it but that's why I got it ,

 

It could be that the engine has had the cams swapped. In any case it's good that she's a runner now.

 

As you say all good now thanks to you boys . Thanks all . Next question what oil in the clutch and how much .

 

Any JSAO MA rated oil (read the second link in my signature for more info). The crankcase volume is cast into the clutch cover near the oil fill hole. If you're changing the filter just start with the 2500cc, run the engine for a minute to fill the filter housing, and then top it off after the oil has drained back into the sump. Having the oil level near the top line on the sightglass is preferred.

 

Glad you got her running. That is a interesting bike and I bet will turn lots of heads. Once you get into the tank and then a little TLC she will be a supper looking bike/trike.

 

Had to go with trike this time getting to old lol . Keep breaking bit of Me . Got ride of Honda goldwing as to big and very heavy at stand still . That one only broke my arm ha ha .

 

I am just glad that you are still riding. Besides my dirt bike days a 1978 Goldwing was my first road bike. They are a beast at stop signs with loose gravel or on a uphill stop.

 

Hey guys .I have xj650 4ko 1983 with TID14-02 4H7-10 module. Is this correct module for this bike? It runs smooth until it reaches 5000rpms and anything after that is no power. Regards from Poland

 

I quick google of the TDI number brought up this: https://www.hoopriderparts.com/product/1980-81-yamaha-xj650-maxim-cdi-ignitor-4h7-10-tid14-02 so maybe it's from a slightly older XJ650?

 

I have a TDI14-02 4H7-10 black lable in my hand . that tci comes from an 80 or 81 xj650
I belive that the black lable tci is from the 1980 midnight maxim non yics motor.
