R80g/s and r100gs shift lever.

These bikes could use some more room between
the footpeg and shift lever to prevent unwanted
shifting.  Not to mention the roller actions seems to
work nice.  Machined from quality 2024-t4 aluminum
and includes stainless steel mounting hardware.  
The shifter is mounted in the first hole in front of the
present rubber shift lever and requires that you
remove the old lever by cutting..  

Includes complete easy to understand instructions.

We're fortunate that NGK has stepped in and are
making plugs for our airheads, after Bosch crapped
out!!

The BP6ES and will work in the,  R60, R75 /5-6-7,  
R80, R80G/S, R90/6, R100/7 other r100's,
The BP7ES will work in the R50, r65's, , R100S and
R100RS 76-80 R100.

Also have some B8ES for a little cooler plugs.

My experience is the later r100's aren't too fussy with
plugs.

NGK has versions for other models, contact me if
interested.

I've one of those Harbor Freight tire changers.  Works
OK and is usually a big help but fails miserably at not
marring rims and won't hold the rims for my R100gs at
all.  So I came up with these blocks to hold the rims
more securely and without scratching.   These are
made from recycled deck material.  Seemed like a
perfect material and a good way to recycle the cutoffs.
Sold in sets of 3.

Seibenrock also has seats and solo seats and racks for you g/s

someone wants and can't afford to stock all. Easy to special
order though and glad to do it.  
Enduralast chargings system

If your bike has points you should be running a points
booster!  They only use the points as a trigger, this
means there are only 1/10 of a amp of voltage going
though your points instead of the whole charge from
your coil.  This means no pitted points and points can
last 3-4 times the usual.  That and if there is a issue
rearrange the wires and you are back to normal. The
only real wear item is the rubbing block so you should
make a effort to check it and keep it lubed.   A great
system!     $90.00
Dynatek electronic ignition

I'm a fan of points myself.  But lots of folks
like electronic ingitions.  Also if you have a
bent  cam tip or a bad points plate replacing
the points with a Dyna may be the best and
or cheapest option, easy to install.   

$225.00
Solid diode board mounts

The original rubber mounts are known to degrade and
let go which can allow wrecking the board.  These also
guarantee superior grounding!   For your r90s or r100.  

$20.00 for a set of four.

Some airhead models BMW built right, if you have a /5 or
/6 except the r90s or a 78-87 r65 or r80 you already have
solid mounts.

I've had numerous requests for plug wires.  These
are nice silicone jacketed wires with Beru resister
caps.  For $20 -$30 less than BMW gets.

Same price for 1k ohm and 5k ohm sets.  Generally
it's 1k ohm for points bikes and 5k ohm for electronic
ignition bikes.
$45.00 a set

"WHAT A DIFFERENCE that booster
makes!!
The R90 runs MUCH better at idle.
Didn't seem bad before but the
change now makes it seem sub
standard. On the road; NO
hesitation whatsoever. Prior; just a
slight pause compared to now.
Much stronger and consistent
overall, NO doubt about it,"

I do lots of Seibenrock special orders for seats, cylinder kits etc.  
Prices are generally the same as what Seibenrock would charge.  
Takes 2-3 weeks and shipping is relatively expensive and there
usually is a currency exchange charge.  Neat stuff, glad to do it,
just let me know what you want and we can see what the deal is.
