problem with starting the bike, relay?

[hellogrish]

hello there,

I have some problems with starting the bike, when turning the key on - all the light turn on
but when to press "start" button the engine doesnt start.
it helped when I kept holding the "start" button and hitting a little bit relay (the thing that have 2
wide cables - one from battery, and another from elsewhere )
but now it doesnt help. to start the bike I have to make "short-circuit" (by connecting these 2 cables
for a second)

the only way out is to replace relay?
any idea where to get this?

cheers
greg

your dealer or ebay ?
if you need to change it anyway you could try to open it.
I found the following instruction longer time ago and translated it from german. I never did try it myself.

The relais on later Ducs is a Toshiba which can be used too, but it requires a mounting bracket. You could also adapt a relais from a jap bike if necessary. (then it would be good to know the max. required currect capacity though)

Does it crank over if you flip the KILL switch to off and then hit the starter button?? These starting problems are common on the paso and if you look in the FAQ you will find posts aboout this and how to fix it.

In the USA we call that BIG relay a "starter Solenoid" .

Sorry, its Hitachi unit

I have added to my 750 Paso such Hitachi and U have to make only bracket for it (easy) and little harder is to make those primary wires connection to relay, as they need suitable connector, what is hard to find..... You can use surely Your imagination, as i also use quite often with Pasos...

ok, thank guys, eventually there was problem with small cable that goes to the "starter Solenoid"
and after replacing everything work fine..

but... another problem I have noticed that my Paso, how to say, starts (mean move away)a little bit
slowly (from the 1st gear), its ok, but some days ago when to starting from crossing, when I get on 1st gear
and release the clutch lever - the bike almost didnt move, and it was quite strange noise from the clutch.
(not this lovely sound of dry clutch ), then when I moved bike away from the street, get on neutral gear
and hold the clutch lever - the noise was really terrible. but just waited some minutes, and came back home
without any problems...

I am going to have my Paso serviced (as I am not good enough yet ; ) but anyway - what could be that?

[paso750]

Antti, you`re right. I just remebered it was something japanese

Greg, at this point it would be just wild guessing what happened to your clutch. It`s just so much it could be. (from worn clutch discs to other worn or broken parts)

[nilaus]

I am guessing that it is most likely the bearing in the slave cylinder which is going going going and eventually will be gone. You can get an replacement kit. which will include: bearing, piston and o ring. But the first thing I would do, is to take the clutch lid of and inspect. Happy paso working

Can You post some details about kit ? Ordering number and price?..availibility? , Duc dealer? EU, or USA? It can help many here!

[hellogrish]

hello,

got the clutch open, and what I saw was a very thin "driving discs"
even some parts of material (they are built from) was missing, and some falled apart
when taking out discs..

yep, that means that I have to replace them, but anyway is this a reason that my Paso
have problem with fast starting? the clutch is slithering because of old driving discs?

cheers

nilaus, so what about that replacement kit? any details?

I`ve got some leakage from this part of clutch so need to do sth with it...

guys, is it easy to be done?

Check the FAQ for the 750, page 1 and you will see a discussioni on how to rebuild the clutch slave.

[hellogrish]

thanks a lot, and do you know sth about driving discs (friction plates) from any other bike?
will it fit?
as I cannot find for Paso...

[streetsurfer]

For the start problem, look for voltage drops between the different points in the circuit. I found my largest drops were at the on/off and start switch in my bike. I had replaced the solenoid previously, with no improvement. Cleaning the switches out and their contacts solved the problem.

I picked up my solenoid at a yamaha dealer, btw.

[hellogrish]

I used a search tool found out more and...
anybody used friction plates from Suzuki GSF400?

[hellogrish]

guys, sorry for being so boring with my problem buy anyway it`s only way to learn sth more...

can you take a look at these pictures?

I just take clutch cover out, pressed the piston with my hands, got the clutch level hold,
and got sth like that: (i cut out my dirty fingers )





dont you think that piston should come out more?

and here how it all looks:





what do you think about it?

cheers
