Hi there, yes if you run LED headlights the AC lighting coil won't light them up. But in theory that doesn't stop you running everything (all LEDs) off the battery and simple charge the battery from the charging coil.
Back in 2011 I wrote a detailed write up about converting my DTMX from 6v to 12v long before it was available in kit form. You might find it of some interest. Give you some idea of what's involved.
However, as Mark points out, worthwhile speaking to RexSpeed for sure.
It's in the Workshop section.

Well done Albert, we should sticky this as it often comes up.

Are we the only two about these days?

Better get your arse out there then Snake!

Happy New Year to you all, here's hoping 23 is somewhat better than 22. !!
As I continue to renovate our house my bikes sit in the garage drained and under covers but otherwise neglected!
hopefully this year all my efforts will complete my project and i can get out and about again on my bikes...here's to 23.
Cheers

Welcome mate, and a Happy Christmas to you.
Nice lot of old bikes there, I've got the 175MX and my 400/4 (as listed on the left there)
Hope you enjoy your time here, it's a lot quieter here these days with little being added so do make use of the search facility at the top to find older posts.
All the best, and a Happy new Year to come.

Merry Christmas to you ALL too. Quiet day down here on the South Coast, took a walk along the beach after dinner and only saw a handful of people.!

You're welcome Stuart
However, I'm slightly intrigued by your name!....have you more than one bike?
Your name is RS100 Dave....not RS200 Stuart?
-
Have a gander at this Stuart, you may have already seen it. A bit on the RS200

You're welcome stuart,
I've got a couple of eye loupes one is 20x and 16x and I think the other x2, but I must confess I've no idea where the 20x one is!!!, I've just looked and its not where I thought it was!
None of them are big, hopefully I won't have a buy a magnifying glass to find it
Although I have both my BIkes on Microfiche, I also bought the parts books when I found them, so the microfiche is just of historical interest and forms part of small collection of literature I've collected over the years on my bikes.
I've also given you a few thanks and now you've got a Gold place on the Leaderboard!

Just been browsing the net for the past hour or so for you.
indeed 3L2 is the RS200 dating from 1980, can't find an online parts catalogue for it or pdf parts manual.( takes someone who has a copy and interest to have uploaded it in the past and still be sitting on a server somewhere!! )
Looked on ebay of course, including the 'sold and completed' items and didn't find anything either. Occasionally a microfiche becomes available (i've bought some in the past) these were often the only source of information for all products as it was a very popular format back in the 70's 80's. You don't need the official microfiche station to view them, I remember having one at work, but you can read them with an eye loupe and bright background light. Sometimes you have to get these sort of things if you run an older vehicle. So if a microfiche becomes available it might be worth buying one.
The picture of the 3NA gasket shows a compressible cone gasket, these fit into a cup like structure on the silencer or just inside, and the castlelated lock nut compresses the gasket around the downpipe.
If the downpipe and silencer are similar size then the gasket might be a ring one, Often a soft asbestos like ring which fits down inside the silencer onto an inside lip, the downpipe slides in and is pushed into the soft material making a gastight fit. I've seen bikes in the past that used this arrangement.
An acceptable alternative (and may be a solution for you) is exhaust paste: smeared onto the lip inside the silencer and the downpipe pushed into it. The exhaust heat cures it and it goes rock hard. Seals the joint but it can be difficult to remove.
Having said that, sometimes it's not as good as it sounds and always cracks up and starts blowing again and you end up repeating the process on a weekly basis!!!....which is why they invented exhaust joint tape!! and you'd wrap this unsightly silver bandage/tape around the joint, it would cure with the heat, go rock hard, enough to get it through the MOT and then fail a few days later!!
But by far the best solution, would be to use the proper gasket, like I said earlier, you may end up using something for another model or indeed another make of bike. It's all down to knowing what it looks like and how big it is. The part number will really help you.
-
What sizes did you get when you meaured the downpipe and silencer Stuart?
Ive looked up this part number 3NA-14714-01 and its OD 1 1/2" ID 1 1/4" 5/16" wide. (39mm x 31mm x 8mm wide and found that it supersedes the following part numbers :
132-14714-00, 132-14714-01, 3NA-14714-00, 3T5-14714-00, 4YYE-4714-00 and fits many bikes but the RS200 is not listed amongst them. ....but if the size is right??

Stuart, most 70's and 80's bikes had sleeve gaskets that fit over the downpipe and they are not very thick, and the silencer then fits over the whole lot, clamped into position. I'd venture to say that theres a good chance they used the same gasket for many of these similar bikes. It wouldn't surprise me if you said the RD200 gasket and RS200 are the same , and it wouldn't come as surprise to learn it was the 3NA-14714-01 !!
if you click on that link above/below
.https://www.ebay.com/p/1737220622?iid=372598027432
clicking on the picture gives a nice exploded view.
For the price bud, I'd buy one anyway just to see if it fits!
-
you're welcome,
YB100 models theres an exhaust gasket for sale on ebay now, might be worth looking at,(gives the part numbers ) ask the seller for the size of it?
this link
https://www.ebay.com/p/1737220622?iid=372598027432
is the same part number which is compatible with the RD200.
have a look at the picture.
Also....If for example it's the same size as a Honda one but the Honda is too long, a fine hacksaw could make two from one!!!

hi there and welcome.
The trouble will always be finding new old stock of parts for bikes (and cars) which are not only nearly 40 years old but also of relatively low production models.
I assume you are referring to the silencer to downpipe sleeve gasket? have you got an idea what shape it is from the parts catalogue or is it a ring gasket?
If you have the yamaha part number, then the website Cmsnl.com have the facility to list which other bikes the part number shares, you could then look up parts for those bikes to see if you can find one which is available for another yamaha bike.
Having some measurements will help, the inside diameter of the silencer and the outside diameter of the inserting downpipe is a good start.
An alternative to consider is a universal graphite sleeve Silencer gasket that may be suitable? such as Ebay item number:204064690445 which has a 38mm ID 45mm OD.
Alternativley look up other makes of bike on Ebay which also have a graphite sleeve gasket for the rear silencer and look at the sizes to see if you can get one to fit.
My Honda 400/4 has one , and is readily available for example and a look on ebay shows its size 32 x 37.5. and that happens to be the same size as a Honda VFR700...and its cheaper!
Hopefully that info may help.

How did you find out what they were for? Did you scour ebay or something?

That's good news , at least you've got a spark. Did it start with new fuel?
You mention 'gas', are you across the other side of the pond?

Well done Graham, hope you get it sorted, let us know how you get on.
Got myself an "Enthusiast" badge with my post! decided to hand out a few "Likes" and thanks to get the rankings chart going as its been empty for weeks!

You might not think my reply is related...but bear with me!
I know nothing about modern motorcycle electronics! however i do own a Vauxhall Astra! it has OnBoard Diagnostics (OBD2) which I am familiar with!
Now there are a couple of things which may be of some help...with my Astra, if a Diagnostic Trouble Code (DTC) comes up, replacing the faulty part with a new one results in the code being cleared....but not always!!....sometimes the DTC is stored in a different part of the memory and you have to 'clear' the codes manually by resetting. In my case via my laptop software. if not the code remains on screen or is shown as a series of a flashing light on the dashboard as it's stored historically.
Your Yamaha is likely to have some version of OBD and the interface socket will be hidden somewhere. It may be the DTC 7000 is on display and waiting to be cleared/reset. Have another read of those threads, does it go on to say how the code is cleared or the procedure to clear it.
it's just a thought. I'm not saying yours is the same, but it may be useful information.

Thanks for the circuit diagram, that's certainly not an easy diagram to follow, they've come a long way with how there are presented today compared to 1964!!
Nonetheless, with a light bulb you can test quite a bit!
Firstly are you getting a voltage on the LT side of the coil ? (LT low tension)
The starter/dynamo has an orange wire going from it to the LT side of the coil, disconnect it at the coil and put a light bulb to earth, does it light up on turning the engine over?
-
Welcome Cdn,
Sounds like you've replaced ALL the key components, so assuming they are all wired correctly and compatible with your bike, I'd be looking at the "kill switch". Now I'm not familiar with the YA6 or have access to the circuit diagram, however, on many bikes of the 60's and 70's they had a dedicated switch to ground the coil and stop the spark, older bikes, the kill switch was wired through the ignition switch, turning the key to 'off' grounded the same wires. Just because the ignition switch "works", doesn't mean it can't be faulty!! Like I said the switch will 'ground' the circuit. To test it, you would need to disconnect this wire so the switch can't ground it. (The switch may be faulty and be grounding the wire in any position thereby killing the spark)

Welcome Jim
Hope you find things of interest within the webpages. I'm only a couple of years older than you (61). I've also got a DT175MX 78 model but registered in 79. I've restored mine and they are very easy to work on. I've got lots of photos of the engine/gearbox strip down which may be of help to you. Having said that, the best advice I can give is to take lots of photos with your phone/camera, I took hundreds as I worked on it, which were also invaluable on putting it back together months later. Its not like the old days of processed film, it doesn't take up any room on your SD card! and you can easily delete what you don't need.
The forum is very quiet these days, hardly anyone seems to post, me included . However, I do glance at the site most days to see whats going on. If you have any questions ask away, and if i can help out i will.
Start a new topic in the Workshop section if you have any questions.

Any Particular bike bud?

Hi there, It would be helpful to know what the typical 8 pin CDI was originally intended for and then read/view the circuit diagram for that bike to be sure. As your two photos supplied, one is for a pin out of a 125Z, and the other has different pin outs for a different fitting.
Having said that, you're confident you are getting a voltage/signal from your generator and pulse circuit without the CDI being connected?
If you are, then presumably you're having trouble getting the CDI to produce the spark, is that right?
your links don't work so well, so here they are...
You may have already seen it, but I found a useful video explaining about an 8 pin CDI which may be of use to you.

Hi Clive, Keith is what we call a One Hit Wonder! He only made one post (the number 1 above his current bikes indicates the number of posts he made) This was some three years ago ....never to be seen again.!
He may well have a valid reason for never posting again, but there are plenty of One Hit Wonders who we never see again.
Nonetheless , you rounded off this topic, so i think this topic can be closed off and locked to further posts.
You get a thanks from me for taking the time to write.
