Extra TCI uniits

I have 4 Tested tci units that I wil part with if someone needs one.

 

Post up the models that they are from and the part numbers printed on them. You'll likely get more responses that way.

TCI units are different between the different models in terms of spark advance, which I'm pretty sure is a function of displacement, and also might be different between maxims and secas.

 

It is for some Secas and Maxims anyway.

 

Ill try to get around to it tomorrow and post some pictures.

 

Little unsure of the model these match up with the red ones "5G2-10" are labeled for '82 XJ750's.....The yellow are actually red TCI unit's just faded from the sun. The side covers were missing.

The 4H7-10 has writing on it that says 650 but in the manual in a picture under the 750 electrical section it has this tci type in the illustration...which doesn't really mean anything..

They all work but in need of an XJ wizard to clarify which is for what!

 

where is a wizard when you want one??

 

I 'think' the first one -4H7 is for a 650, all the rest -5G2 are for 750, same as mine.

 

That's my assumption too. Taking offers and I'll ship anywhere for $10 flat rate. Individual or the lot.

 

This may assist with the ID process

Doing a part number comparison. This is what I have come up with.

Non-YICS
The 4H7 was originally used on the 80-81 non-YICS 650, and then replaced by the 5V2.

YICS
The 5G2 was used for all the 82-83 650/750 YICS

curious......I wonder what it was that made them change the units?

 

My guess would be a timing advance change in the YICS engines.

Thinking of puchasing a spare tci 5G2 as a back up. Can u PM me with an idea of the approx price your looking for. That and standard mail to UK

 

I THINK, though I'm not positive, that the 4 stands for 4 wires in the connector, the 5 for 5 wires. I believe the 5th wire is the kickstand switch, which started in 82. Yes, I have a 4H7 in my 81 xj650.

I changed mine last year to solve a tip-in stumble, which it did solve.

 

Permissionto land, Thanks unit arrived in UK earlier this week. Only down side is UK customs slapped an import tax on it! Currently arguing with them but had to pay to get it released.

At least I now have a spare TCI unit which should keep my bike going if my original fails!

many thanks

I've had that problem with the bastards, so what i do now is to get the seller to write on the export form as a gift and to make out the price as low as possible.
The last item i bought from USA was an XJ1100 TCI unit which cost me £130 plus the p&p. I asked the seller if he could do something about the export form and he said yes.
It came as a $10 gift with the postage more than the make believe price but at least the Customs and Excise were non the wiser.
I've been stung on carbs imported and allsorts. Bastards. It's secondhand and already had VAT paid and those fookers still want more.

 

I'm a little bit confused as for what would be the correct TCI for an '83 Maxim 750cc...can anyone tell me for sure, because it doesn't run properly and I wonder if it could be the problem (or one of the problems)?

 

fj111200, Next time I will ensure that cost price is below tax threshold £15.00 GBP.

And as you say 2nd hand, 30 odd year old is and still accruing import tax is a joke. Rip off Britain!

 

Quebecois59, Not exactly sure for definite, but I'm sure the gurus will confirm. prety sure that your looking for the same TCI unit as being offered by permissiontoland.

Has your tci not got the reference numbers/ data plate attached?

 

I don't have it next to me, neither even close to my place (bike is stored 40 minutes from home).

 

A 5G2 - 10 would be the right TCI unit for your bike.

 

OK I gave myself a kick in the butt (sometimes I'm lazy on saturday mornings)and had a look at the parts diagram. It seems that the proper TCI unit for my '83 Maxim 750 is the 5G2.

Actually, the 5G2 unit is shared by the following models and years:

'82-84 Maxim 650
'81 to '83 Seca 750
'82-83 Maxim 750

As for the 4H7 TCI unit, it is shared by these:

'80-81 Maxim 650
'82 Seca 650

They also list a 5V2 TCI unit for these last models and years, don't know why.

Hope this would help.

Nice. Leave it to Len to give the nitty-gritty.

I'm printing this one out.....

Excellent wrap-up, indeed.

I don't understand at all what all of these advance numbers could mean, though. Could it be enough to make a '83 Maxim 750 run very rough if you put a 4H7 unit while a 5G2 is the right one?

I can't remember exactly which one I put in, only thing I remember is that I was told it would run ok, but it didn't. This said, there are plenty of things that could be wrong except the TCI (compression not tested, valves not set, carbs not balanced), but it would be a good start to put the right TCI in.

 

The advance is telling you when the spark fires in degrees of crank rotation before TDC. Having the wrong advance curve will definitely affect how well the engine runs as spark advance is dependent on the valve timing of the engine. While it is possible to run with spark timing that is different than stock (sometimes it's preferable, depending on the engine), if you get too far off the engine will run very poorly. If it were my bike I'd get the mechanicals done first before trying another TCI. Fix the things that you know are not set correctly before messing with anything else; eliminate the known variables.

 

Lol thread bumped from 2012?

 

Wow hadn't checked this thread in awhile. Thanks for all the advice.

 

Due to a purchase made in 2013. Makes sense to me.

 

K-moe, Your right permissiontoland advertised and I purchased, as he has more units others may wish to contact him? If he can send it to the UK then and it is as described. I will bump the thread for him.

One good turn deserves another!

 

Thanks CapnReadbeard

 

I'm having an issue with my XJ750, my CDI it's working fine but accidental I cut the two wired sockets and I don't know how to connect the línea with the pins on the CDI, can someone heló me with this?

 

this thread has the correct locations
https://www.xjbikes.com/forums/thre...j750-simple-wiring-with-a-cdi-question.35298/


you can use this connector if needed

 

I have an 82 xj550 t seca and im told woll interchange with the 650. Correct me if in wrong but id like to have 1 on my bike at a reasonable price or possible trade.. the one i had was stolen so ive wired HEI modules and no advance is still my issue. Thanks and please let me know

 

the tci for the 550 650 and 750 will start any of the xjs 80 to 83 but your bike will not run properly without the correct tci
you need a tci for a 550 ? what do you consider a reasonable price?

 

Im coming to find out how hard they are to come by and so i honestly dont want to offend u and low ball you. Im a biker and really just love the ride, the freedom and on this bike the balls she has for being a 550. If u dont think my 550 would run right with a 650 TCI can u explain your reasoning? Cause you have 650 TCI right?

 

I have the 550 tci and a few 650/750 tcis
the timing is different on the 550 than the 650/750. we had a member using a 900 tci for his 550 and switched to 550 his problems were solved.
the 550 parts in general are becoming harder to find on ebay even new parts needed parts

ebay selling tci for 80$ my near by parts yard 160$

place an ad in our wanted forum you will get some decent replies

Yep that sounds like the one that was in this bike. The blue is what i know. Now that seem like a pretty huge advance considering my knowledge on the HEI im trying which i believe only has a 17 - 36 degree curve.

 

$80 sounds fair but i am skeptical purchasing used electronic on ebay. My whole purpose of joining this group is for knowledge and a bwtter sence of reliability in everything. See i would have felt dumb offering you $25. If you would sell me it i wouldnt have the money for a little while but if u hold on to it i will be buying it bfore too long

 

I'm using two CDIs from bajaj, and my XJ750 is doing even better than with the original CDI, low and high speed working properly. I just came for a 479km trip and it's still working

 

Cool. My bike runs a TCI ignition system.

 

there is a way to fix tci but sorry to say it may be a little more than you could do . it intimidates me too.

 

props to you. I am always impressed but the ingenuity of my neighbours from below our southern boarder in keeping motorcycles running

 

I just fixed mi TCI unit, but I'll keep using the 2 CDI from bajaj, but I'm having issues with the carburators, do any of you gusy know how to regulate them on the XJ750? I never did that before, and the problem is that I don't have the tools to do it properly... Veré is a pic of my baby, I'm creating a Cafe Racer
