Wiring/Starting Help - Suzuki GSX750 1980-81 ish

[Guest]

Hi everyone.

I need some help with the bike named in subject if anyone owns one, has worked on them or has a wiring diagram I would appreciate

it very much.

Just picked up a chop project with the engine fitted as mentioned, GSX750 not sure exaclty the age but about 1980-81.

Not much present in the way of wiring loom, but there is a regulator/rectifier, and CDI/igniter.

I'd like to atleast get a spark before blundering on with anything else.

There are HT coils present and a starter relay.

I can get the engine turing over and it will kick out the required voltage from the regulator.

None of the boxes have the plugs on still just cut ends

If anyone knows for definite if any other parts/black boxes are required to complete the igniton/starter circuit, and if not, how to wire up what I have present I would really appreciate the help.

I'm not a novice with bikes or mechanics, but when you don't know if all the parts are present and you can't even find a manual/diagram on the web, it's a bit more tricky.

I have the Starter and relay,

Regulator (3x Yellow, 1 black, 1 green, 1 red) ,

CDI/igniter (1 blue, 1 green as a pair, 1 O/Wh, 1 Blk/Wh, 1 Blk/Y, 1 Wh as a grp of 4)

A Blue and a Green emerge from the R/H/S from the igniton timing pickups off the crank, and I'm tempted to think they might connect to the Blue and Green pair off the Igniter/CDI.... but not sure.

There is output of 14v on the Red of the Regulator when engine turns over.

Just not sure how to connect up the Coils, Reg, CDI, and Pickups, and/or if there is anything missing.

I politely refer back to my first sentence. I'm not looking for generic basic fault finding here, I'm ok with that. It's specific info on the Subject bike that I would really appreciate.

Feel free to contact by PM.

thanks in anticipation.

your reg rec

the 3 yellow are the input from the stator

the others are probably positive negative and charge light

Welcome to TMBF mate.....pop over to the Newbies section and say hello to the guys when you can.....

UK190 has a chop based on a gsx750 engine.....he don't get on here much these days....but may respond to a PM if you send him one. He rewired his and fitted it with a remote starter.....so he may have the info you're looking for...

PM Megawatt too.....he knows a lot about those aircooled Suzukis and used to race one at santa pod back in the early 80's.....shame that the aircooled Suzuki website folded a while back....you would have got your answers for sure on there.....but Megawatt still has contacts from there if he doesn't have the answers.....
