XT600E motor in TT600 chassis

I've bought a 84 TT600 which has been fitted with 1990 e/start XT600E motor, nothing has been connected.
what I need to know is can I use the TT cdi or do I have to get the XTE one, also what capacity battery should I use ?
Does anybody have an Acerbis 20l tank for a TT ?
Cheers John

no, you can't use the tt600 cdi.
xt600e has battery ignition, so you need the xt600e (not xt600k!) cdi unit, ignition coil and switches.
wiring is very different, so you better get also the complete wiring from xt600e.
wiring diagrams you can get here:

not possible to use the old alternator because crankshaft left side is longer.
battery should have 8A minimum.

hell of a work, good luck,
klaus

Thanks Klaus, I read in one bike mag that the ignition on the XTE is transistorised, what is the difference between this and the Tenere cdi ? The motor is fitted with a k/start as well so in theory even if I have a flat battery it will start, it this right ? any idea why they went from cdi to this type of ignition ? John

to understand this, you have to remember the 'roots' of the tenere: she was designed to win the paris-dakar rallye. the ignition is capacative discharge type, the ignition voltage is produced by a seperate coil in the alternator (cables red and brown).
advantage: ignition is independend from battery, so you can start and ride even with flat battery or you can substitude the battery against a capacitor (as yamaha still does in the latest TT600R).
but long run experience has shown that the isolation of alternator coils wasn't very good in those first years. it is a very common fault in xt600 up to '89 that ignition problems occur because of burned coils.
the cdi unit was build from relativly 'primitive' electronic components, lots of resistors, diodes, capacitors etc. again, sensitve to alternator malfunction and also a source of ignition problems.
so, in 1990 when the 3TB was introduced, yamaha changed the ignition system to an more advanced battery type ignition with tcdi unit. it works perfect, but now a good battery is must. only in xt600k (kickstart version from '91 to '94) the old ignition system was still in use.
isolation of alternator coils is much better since then.
although it is possible to fit a kickstarter in a XT600E you might find it very difficult to kickstart the cold engine. reason is the primary ratio (gears on crankshaft / gearbox axle) which is different from before. yamaha has changed this '88 in tenere 3AJ which was the first tenere without kickstart. you simply cannot revolve the crankshaft fast enough with the kickstarter to start the cold engine. but a perfect carb setting might help, try it.
there are also other differences between the ignition systems, i have pointet out only the main things. in '96 cdi unit and wiring system had been changed again.

check also the chain alignment, gearbox axle of e-start engines is 10 mm longer then those of old k-start engines.

Once again I must bow down to a man who knows so much about Yam's.
I can sort the electrics, I'll just have to make sure I don't let the battery to get to drained out but thanks for the tip about the mainshaft, wouldn't have thought to check that, what did you do to yours ? did you space the rear wheel to suit? or will it be ok with such a difference?
I've been to the XT website and I see you have already done this conversion managed to understand some of it but mein deutsche ist nicht gut.

Klaus, I've got the TT motor, could I change the primary drive gears over or is it not worth it? John

to ride with false chain alignment will cause dramatic chain wear. in the worst case the chain will cut the frame.
you have to turn the sprocket and modify it so that you can mount the nut.
gears:
yamaha changed the primary gear ratio in order to change also the ratios in the gear box. another known trouble-maker is the fith gear (pitting). in new gearbox, gears turn faster (for this reason 2ndary ratio is 15/45 since '88). this helps to prevent pitting.
therefore you cannot just change primary gears. if you want to do this you have to use primary gear, clutch and gearbox of tenere 1VJ (only xt with both kick- and e-start). but then i would advice to use the shaft of a 3AJ of later e-start xt because of the fine toothing (is this the right english word?) for the sprocket.

I will try machining the back of the sprocket to fit, failing that, When I bought the bike,the deal was for the TT plus a 87 Tenere, so I could use that motor, will the XTE battery have the ampage to start the tenere motor. John

No, I used the complete cover as well, so I've got a silver motor with a black generator cover.
You said it would be hard to k/start, it doesn't seem that hard, I also own a XT550 and its no harder than starting that!

XT600E motor in ttr600 frame

Hi Klaus
I am from Namibia , can you please give me some advise ,
we have fitted a tte 600 electric start motor into a TTR frame. All wiring and
cdi is TTR . We get the bike to start with the newly fitted kick starter , but will idle for a few secs. with choke on and then dies. Can not rev the motor up at all . whont start without the choke . Im sure it has something to do with the cdi of the ttr. I will backfire or kick back sometime. please can you give some advice , regARDS Eben

That's how a carburetor should be working!
It should only start the bike when you actually pull the choke on!

Keep the choke on until the RPM start go up and than you can turn it off!

If it won't idle after that you have to adjust the Mixture screw and might even need to adjust the throttle stop screw!


Plus, you will probably need to fit all the TTrE electrics instead of the TTr!


Good luck!
