did you test the CDI yet? or even put up a question askign somebody if they would test it like I said to do?

im going to type this out again incase you forgot as i have 2 minutes while the bath fills up.

I still dont reckon they are broken, like I said before you most likely have a wiring fault, as highlighted by changing the cdi (and moving the wires) making the brake light work again.

It could be the switch or a related serach but it could be mny things, you need to FIND the problem instead of
trying to fix the symptoms.

If you goto the doctor he checks based upon your symptoms to FIND the problem and treat that, if you go in with stomache ache it could be anything from acid reflex, cancer, appendicits etc etc.

The doctos doesnt just whip out your apppendix becuase it might be the cuase, he / she will investigate.

If your cdi is not fucked then the bike isnt killing them, if the bike IS killing them you have a more serious problem than the bad wire.

If they are OK then you have something killing your spark right, this is EASIER to find as the spark circuit is small, look at the wiring diagram, something must be shorting out to earth to stop the spark so find that and fix it.

If the CDI is dying then something is much worse.

do the very simple things you are told nd it will become fixed, keep asking how people fixed similar problems and you will waste time money, more time, more peoples time, and maybe eventaully fix it.

Look at the hanyes or honda book, many totally differnet problems have similar symptoms.

bad idling.

-> electrical
-> carb jetting / slow circuti
-> air leak
-> fuel tank
-> vaccum tap
-> valve clearnaces
-> bad balance
-> bad fuel
-> worn plugs / filter.

Now you can see many issues can cause the same sypom, instead of mindlessly trying everything in some random order, identify alll the possible causes, sort them out in the most obvious / easy to check and check / test things one by one until you find the issues.

CDI testing is easy for you, put up a thread, post it to somebody kind enough with a return envelope / box and get it tested.

I've already explained to you my idea about the kill switch. The power for the ignition coils comes for a 10A fuse in the fusebox, to the handlebar kill switch, then to the coils and finally the CDI. If your tail half of the wiring loom is not secured, it's possible you've got damage somewhere on this circuit. Of course, you could have damaged something else, and this is leaving the CDI with no power. I don't know, but I would bet a penny to a Pound that the ignition being lost at random, the brake light working, not working then working again, and any other odd electrical issues are all related to the harness not being secured. Wires don't like flexing repeatedly, eventually the strands will start getting cracks from the process, and the more they crack, the easier they are to bend, and eventually all the strands that form the individual wires will break, and you'll have an intermittent connection that may or may not be affected by running the bike.

okay so ive been away for a few days, and ive quickly tried the new coils and the CDI, and the bike started, i rode around the block a few times, got the temp up quite high, and no cut outs, and no running on 2 cylinder issues etc. like i said i just got back from london, and i have not had any time to check the electrical connectors. which i will do tomorrow. ive got one other issue, and that is the bike running a little tooooo rich. this is strange because about a year ago i asked what jets i should get fr my tsr half system and i was told 118/120 which i did, and it ran like a beast, ive also increased the diaphram hole to 2.5mm and raised the needle by 0.5mm, now im not sure if ive asked this before, but could the air filter be a problem? if so il buy a new filter right away. or try that K&N air filter mod.

Drop the needle if you feel its to rich this will alter the fueling at midrange

Why do you think it's running rich?

because i can smell and see petrol squirting out from the exhaust. like little droplets etc. and also when riding the bike on 4-7k rpm it feels like its coughing up the revs, its not smooth. and i thought it would have something to do with too much fuel getting in and not igniting properly

Petrol coming out of the exhaust ?

Do you keep your bike outside by any chance ?

well, its outside usuall, but not for the past week. i have a small metal shed it was in there. im pretty sure its petrol coming out as i touched it and smelled it and it was heavy petrol smell. there is always a strong petrol smell even when im a meter away from the bike when its running.
i wish there was a dyno place for bike here but there isnt

That will be condensation, if you think its petrol get a lighter bellow the exhaust and see what happens?

I doubt it's fuel coming out of the exhaust, condensation, rain from being outside, and the condensation from being inside a metal box will be immense.

If the smell of fuel is that strong it's leaking it!

So you think it's too rich, what are your carb settings exhaust etc?
