XS650: MikesXS   Leave a comment

MikesXS have never been my friends. Poor product quality control. Marginal materials. But, they were there. Many XSes simply wouldn’t be running without the passion Mike Lalonde brought to his business.

Time doesn’t stop (in a ‘normal’ world). When our universe ceases to exist in the ‘reality’ we experience, time, as we (mis)understand it, wont. We get older. Our priorities change. We move on.

This has happened to MikesXS. Mike had other plans for his life. As it should be. The business was sold. And we, as consumers had high hopes. Of improved quality control. Of better customer service. Of continued access to parts.

And what have we got?

I don’t know about you but I have heard no end of owners grumbling. My order hasn’t been filled. Or only partially filled. Parts on backorder. Mikes are ‘awaiting a large order currently on the docks’. The list of unavailable parts seems to get longer, not shorter.

In the 70’s I was interested in a career in finance. Economics was, and still is , a fascination. What eventually soured me was a takeover (of the company I worked for) by Asset Strippers. They sought private and public companies with market or share values lower than their toal asset value and simply stripped them. Sold the existing stock. Sold the assets. Split what was left into smaller Business Units and laid everyone else off. Fortunes were made by the few. Families and whole communities were destroyed. Real progress! And it hasn’t stopped. Wont, until blood starts to flow. :79:    BildBild

What does this mean for us?

I was taking a quick look at the German forum over the weekend and found this from Rüdiger, owner of the XSShop Kiel in Germany:

Hallo XS Freunde,
die neuen Besitzer von MikesXS in Florida haben leider die Ersatzteillieferungen an mich eingestellt :( , es zeichnete sich schon kurz nach der Übernahme des Geschäftes eine Verschlechterung ab, teilweise bekam ich nur knapp 50% der bestellten Teile geliefert.
Bei Nachfrage in Florida wurde mir mitgeteilt das MikesXS keine Teile mehr von dem Hauptlieferanten aus Taiwan bekommt ( keine Ahnung warum ) und sie somit die Lieferungen an Ihre Vertriebspartner in Japan und Europa einstellen :( :( .
Ich werde nun zusammen mit Heidentuning die benötigten Teile in Eigenregie importieren. :D
Das ein oder andere Ersatzteil wird somit sicherlich kurzfristig ausverkauft sein aber es kommt wieder rein. :D


Basically translated as:

The new owners of mikexs have stopped delivering to me … soon after taking over the service deteriorated and they started only supplying part orders … on enquiry they said that they were not dealing with their taiwanese suppliers anymore and in future would not be supplying their business contacts in japan and europe …

Jerry Heiden and myself are now planning on importing our own supplies (from taiwan??) and expect to be short stocked in the meantime … this will not last

Sounds like some underhanded dealing happening behind the scenes somewhere … ??bills not being paid by the new owners?? … ??setting the scene for massive price hikes?? … ??deliberate minimal shelf stocking?? … ??cashing in on existing stock to pay their own bills?? … cant at all imagine Rüdiger or Jerry not paying their bills-be like shooting themselves in the foot.

Asset Strippers at work here? Locusts? An attempt to cut Jerry and Rüdiger out of the profit chain?

I don’t know. I do however have a distinct sense of déjà vu.


or are all of mikesxs_ awaited containers here

or are all of mikesxs_ awaited containers here


Guess we will have to wait and see.

Happy riding.

XS650: Model, Year, Model code, Engine Number   Leave a comment

I made this list up some years ago. This version is arranged in Model Code numeric sequence. This code is found on the steering stem ID/VIN plate and Registration Papers. This is not necessarily the same as the first 3 places of the Engine Number.


XS-B            75-76                 533                        447-500101

I’m sure it’s not complete. May include errors. If you have a machine with a model code not listed here let me know.


… by model code – page 01


… model codes – page 02


Or here listed by Engine Number.

… by engine number – page 01


by engine number – page 02


As you can see, there are questions. (???)

… my original tables included these model code/engine number combinations … they are not however confirmed by Yamaha … if you have a machine covered by one of these please let me know and I will reinclude it in the above tables


Have a Model Code that’s not listed here? Let me know.

I wish to get an idea of production runs. The engine numbers in the above tables are arranged so … 447-300101 to (400000). I have the start number for each model. Yamaha have given the absolute end number-these are in brackets. Not necessarily the real end number. Where I know this I have entered it without brackets … 2F0-000101 to 006141. The information is from Yamaha Publication #12100-100E1.

I’m looking for approximate end numbers. If you want you could leave me your model and engine number. No Name. No address. When left in the comment box below no one will see it.

XS650: Patches   Leave a comment

My wife reckons I’m entering my second childhood. Secretly I know I never left the first. Life has been one endless playtime. Maybe I’ve just been lucky. I’ve been paid to travel the world and work in many different places and countries. Until I got married (at over 40 years old) I’d never stayed in one place for more than 2 years since I was 17.

I belong to the Australian XS650 Club. When you join you are given a club t-shirt and a small sew on patch.


1 .. sew on club patch ca 85mm dia and t-shirt front logo

2 .. club t-shirt rear logo

If you’re caught on a club outing or as a club representative without one of these you have the choice, beers all round or the naked dash.

To cut a short story long, I went to the 40th birthday celebration of our beloved XS650 a couple of years ago. Of course, I wore my t-shirt and made the effort of sewing the patch onto one of my vests.

I had found one of these on ebay too. So it got sewn on as well.


3 .. engine patch ca 100mm dia

At the event I was kindly given one of these from the Wuppertal/Ruhr Stammtisch, the event organisers.



4 .. Wupper Ruhr Stammtisch patch ca 90mm wide

Since then I have gathered several others.

And of course this take-off.

And this oldie from way back.



11 .. rather large.. ca 200 x 120mm … apparently also available in a smaller size too

12 .. from the heady 70′s … there is also a bigger one – around 7″

I have some other XS650 related patches somewhere. No photo yet.

Also some other generic Yamaha patches etc that I have sewn onto my vest as well.



13 .. vest – front

vest – front



14 .. vest – rear

vest – rear



This project isn’t finished yet. As you can probably see. Funny thing is, since I started sewing these things on after the XS650 40th Birthday Bash I’ve never worn it. My son does. Under my protest.

If anyone is interested the vest is from Carhartt. US brand work clothing I was using in the Yukon. Pretty warm.

If you know of any other patches let me know. Or send me one.

XS650: Why?   Leave a comment

Consumer Warning: This is going to be a short personal burble. If you’re not interested click further.

Several people have asked me lately why I’m doing this. Good question. I have no real answer.

I guess it started with me contributing on forums. A great learning curve. For me. In my way.

I’ve had a very successful career in the exploration sciences. Involving systems analysis where the origination and degradation phases become super important. Means reading and researching. Multidisciplinary. Then channeling that understanding through cat-time to various pasts and futures. Allows you an insight into what to look for in real time. Not everyone is as successful.

I like questions. They’re starting points. The ultimate answer is often only indirectly related. Not everyone does. They don’t really have the answer.

This is what I like, and dislike, about forums. If you have a question you can sometimes generate enough intelligent discourse to get a clearer direction. If it becomes too big, without personal contact, mostly it’s simply lazy people not interested in learning for themselves. Looking for the quick fix. Not really learning. Same things. All the time. Or you have a language problem.

Brings me back here. Why? For me. I never really expected anyone to read this. Surprises me that you do. It started because I had charging, oil and clutch problems. So I went looking for answers. Kalles’ external filter, the PMA, and Peters’ 8 plate modification write up made sense to me as did the billet basket and vescanite blocks. So I went there. With results. Not to mention the rephase.

My 650 had a totally new lease on life. Still, there had to be more. Inexpensively. I had done a lot of porting experimentation on my XT500 heads. With some successes and some failures. And when I get hold of 650 heads I do the same. Playtime.

I read several languages. English German Dutch French. Some are easier than others. I write english quite well. German very badly. There are lots of things happening out there in the XS world. But little communication between them. In my curve I’ve touched all these worlds.

This. Is really for me. A way of organising my information in a way I can find it. In a way that makes sense. To me. There is no particular order. No real beginning. No end. If you can make sense from it I’m happy for you. If you can’t you can always formulate a question.

As I say, it really does surprise me you’re reading this. It’s kind of flattering really. I have not advertised the site. Not made a big noise. You’ve found your own way here. If you come back it’s your choice. If you have a problem with it all you should contact me. I can’t promise you satisfaction but I will listen and take you seriously. What I write is pretty much only my opinion.
