XS650: 650 Central Sump Extensions   Leave a comment

650 Central has started producing a sump extension kit. MCEN40-2750. You wont find it listed yet.  A serious performance modification. 2 3/4″ deep (69.85mm).
Lowers the oil level freeing up the flywheels and clutch basket. Less flywheel drag implies better dyno numbers and lower oil temps.

Kit price … $135.

  • extension-(cast for better heat dissipation),
  • SS bolts
  • 2 gaskets

The name I refuse to repeat sells brass versions.

Steffi, from Switzerland, dedicated XSler, wrote a post on the german forum. Provided the following picture …

Offered a 1 off opportunity to get some. He has been making these for over 10 years now, Tried and true! Stainless steel. Innen chamfered. Sealed with an o-ring.

Was intrigued. So bought a few sets. Have no doubt they work. My personal experiences with his XS products have been nothing but positive.

XS650: Engine Nuts n Bolts   Leave a comment

Been thinking about tarting one of the old girls up a little. Nuts n Bolts. But which?

  • Alu?
  • Stainless Steel?
  • Titanium?
  • Phillips Screw type?
  • Hex socket(Allen key)?
  • Hex Head?
  • Race Spec?

Not racing so I dont need them drilled. Weight isn’t really a factor so I can’t justify the expense of Titanium. Aluminium? Stainless steel?

Pro Bolt has an interesting selection. Outlets in the UK, USA, Australia, Germany, Denmark, France, South Africa.

 

aluminium, hex socket – allen key … gold, silver, red, purple, orange, grey, black, blue

 

stainless steel … hex socket – tapered head (allen key)

 

stainless steel … flanged head hex bolt

 

Titanium … race spec – drilled … flanged head hex bolt … silver, purple, gold, blue

 

aluminium … race spec – drilled … hex bolt

 

titanium banjo bolt – single … 10mm – hex socket (allen key)

Next problem. List of required items. Went through an old engine. Put this list together…Haven’t checked it right through so may not be 100% correct. XS650E.

XS650: XS1B Motor Schematic   Leave a comment

It’s a better machine. The way it should be. When you know how they’re built. Traditional and tough.

Simply the best!

XS650: Buying Heads or How to Throw Away Your Cash   Leave a comment

Our beloved XS650s have become pretty popular these last few years. They look good. Sound great. Ride well. Classics.

This has driven prices up. And created a market hungry for parts. A market of often inexperienced buyers. Unfamiliar with these machines. Unfamiliar with their idiosyncracies.

Slowly, backyard and enthusiast businesses are beginning to cater for this market. See for example, the Australian XS650 Club here, and JBM Industries. One of the main reasons I started this blog was to promote such endeavours. I have personal experience using most of what you find written about here. The other reason was to provide options to those useless crap new parts as sold by the supplier whose name rarely passes my lips.

Ebay has also provided a ready venue for bike dismantlers (often these bikes are worth a lot more as used parts than as complete machines). Many of these online sellers are straight-up. Others NOT.

One of my pet hates are assholes that sell Heads and Rocker Covers as separate items. If you buy these you are literally wasting your cash. You would do better going downtown and buying some homeless person a meal. Karma rules!

You need to be aware that Heads and Rocker Covers were machined by Yamaha as a matching pair. And stamped with matching numbers.

matching numbers…6198…found behind the oil feed pipe

mismatched cam bearing mount

mismatched numbers… J1954/9450

surfaces dont match

valve inspection port misalignment

single head … €85 wasted … and no cam

single rocker cover … $72.99 thrown down the toilet … at least it has the rockers and inspection covers

These sellers know very well that these should be sold as matching sets. How do I know? I have made it a point to let them know. Does it make a difference? Obviously not!

The current Ebay Hall of Shame:

Took me 5 minutes to find these ………

  • thebikebarn … head only, valves and springs, no cam … £60 wasted
  • Impala66k … cover only, no rockers etc … $72.99 blown
  • Impala66k … head only, valves, springs, no cam … $149.99 down the toilet
  • wilto54 … head only, no cam … $125 you may as well have given to a thieving banker
  • independent-cycle … cover only, rockers … C$44.95 don’t you need snow boots?
  • elkhntr6x6 … head only, no cam … $99.95 you should have given to the homeless
  • juan.fernandez … head only, valves, springs, no cam … $99.95 throw a party instead
  • motorcyclesalvation … cover only, no rockers etc … $25.49 you should have spent on new oil
  • bigfootedalien … XS2 cover only, rockers etc … $100 ??wtf??
  • bigfootedalien … cover only, rockers … $57 your ex could have done with
  • bigfootedalien … head only, springs, valves, no cam … $95 do you need a tyre?
  • thecyclebarn1 … head only, no cam … $79.99 worth of BC Buds you missed out on
  • thecyclebarn1 … cover only … $49.99 you paid for scrap metal
  • yourtrashmytreasure … head only, springs, valves, no cam … $195.99 better spent at a brothel
  • yourtrashmytreasure … cover only, rockers … $79.99 worth of condom insurance

Be aware that Engine Cases are likewise machined as a pair. And also stamped.

matching case numbers … 3062 … found behind the clutch pack

look here … 9426

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

Rüdiger

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?

 

Guess we will have to wait and see.

Happy riding.
