View Full Version : What am I looking at?? XS650

05-14-2015, 12:52 AM
I recently bought this 1983 xs650 on Craigslist and thought I'd tune it up and set the timing and points.. When I opened it up I don't see any points or anything like my Haynes manual suggests can anyone tell me if this is the stock ignition system? Bike starts and runs fine as it is.

That would be the stock tci ignition. They switched to that sometime early 80's I think.

Yeah like Diesel said it's a TCI which started in 1980 with the deletion of points and moving everything to the rotor.
Do a bit a reading up on an alternator and ignition upgrade since the above is usually the weak point in our bikes, though I will say that looks really clean.

If the ignition and charging work, leave it alone. Mine is an '83, all stock, runs and charges great. Just changing to a PMA requires a diff ignition. That is an expensive ordeal.. Some riders have even fixed their faulty TCI by replacing blown transistors.

Thanks for the replys guys I was looking into upgrading the ignition but looks like I'd have to buy something like a pamco and a PMA (is that correct for an 83) which I don't want to put the money into at the moment.. The real reason why I wanted to adjust the timing is because it's kickstart only and bites me almost every time I start it so I was thinking adjusting it would help im getting full charge from the alternator and just replaced the battery so I'm thinking that's not the issue with it taking around 10 kicks to start it.

Starting difficulties and backfiring may as well be carb related, leaky intake rubbers or something.

I agree with it maybe being a carb issue. I've had a tci xs in the past and it was always a one kick bike. If it's charging then there's really no reason to swap over to the other stuff. As has been said you'd have to go with a Pamco with E-advancer or source an entire mechanical advance from somewhere. If you swap over to a pma, the ignition swap will be mandatory.

Sometimes it starts 2 kicks sometimes 10 when cold after it's been running always starts 1st kick from the store

Sounds like what mine did. Until I grenaded a piston due to a lean condition. Check your intake boots! Mine had tears on the bottom side that I never noticed until tearing the motor down for a rebuild.

Check intake boots, exhaust gaskets, and carb tuning. Good luck amigo. Looks like a clean bike from those engine pics.

@pendulem the guy I bought it from said the carbs had just been rebuilt buy you never know.. Seems to run fine when started clutch cable could use adjustment..
I just put some moto bars on it and grips to match the front brembo not bad for a 31 year old bike
