It sounds like you had a lemon, Gryph. The sensor on mine works reliably. Never use mine on expressways, mostly for oncoming, close quarters.

finished up the LED wiring, then put tank back on and started her up.  yuck!  when you mess with everything, it runs like crap!  went through full set up process with choke set, fuel pressure check TB balance and idle adjust.  much better.

all brick'd up and ready for the snow to melt..

Marshall I really love your seat never seen one in OZ. 16years and 120,000K's ago I was warned by a BMW expert and others, to replace my NGK leads with OEM leads otherwise my computer would blow. If you insist in using those leads, you will forever live in fear and your bike will be damned. Any day now might computer is going to blow and send me to hell.

The dress of the plug leads doesn't look right.  The lead for the #3 cylinder is too sharply bent.  It should enter the space across the top along with the other leads, and then curve down to approach the plug from the bottom.

DOOMED Marshall you and I will now end up in purgatory, along with our bikes for using NGK leads. So whoever gets there first can check the joint out, and work out a good ride.
See you in HELL a DOOMED & TERRIFIED Martin I'll be waiting. :musicboohoo:

OMG!!!  :mbird  I bought a set of NGK leads for my RS.  Thought I smelled a bit of sulfur when I opened the bag.  I think it's gonna be crowded down there.

time for the headlight circuit upgrade.  got the Eastern Beaver  "hardwire" version.  very nice quality, shipped from Japan.


unplug and remove the stock bulb socket. 


cut off the connectors, strip back the yellow and white (the hardest part of this whole job since the wires are short) and connect to the EB harness with the twist locks. notice the shrink tube already on the EB harness.  used heat gun to shrink it after making the connections.


I hated to cut off the very nice power wires on the EB harness with mini fuse holder, but i had already run fused power from the battery when i had the bike apart.




SNIP!  then used some connectors to join the stub of the EB harness with my power wires.


tucked the wires up into the fairing, tie wrapped them in there and turned the key.  Light!  all works fine.  will get a higher wattage bulb at future date.

 Marshall after sixteen years of going to fit relays. I finally fitted them while my fairing was off undergoing repair. I managed to do it without cutting into the original wires, and I bought a new ceramic H4  plug. After checking the light output in the garage, and thinking great improvement, it was a disappointment on the road. I will now chase up better globes.

lesson for today...just because an old part looks ok does not mean it IS ok...

been chasing the tuning on the bike since I did the rehab.  clearly running lean.  did the propane test.  definitely an air leak around the base of #3. hmm.  only parts i did not replace were the lower "gaskets" between the TB's and the head.  i had taken one of them off and it looked good.  oh well, ordered three new ones...and...took the whole top of the engine apart again.



sure enough, the old ones were original and although soft, there is a raised built in "o-ring" on the bottom of these things.  20 years of being snugged against the hot head had resulted in them being flattened.  no seal.



new ones


will test run and retune later this week.

project #2...when i went to put a 100/55w bulb in the head light, the old bulb just fell out.  some prior owner had broken the metal locking lever off the lens.  argh!  bought new one.  OUCH!

broken one.  you can see where an attempt to glue was done at some point.


old and new


had to take half the fairing off to get to the headlight lens.  many thanks to the instructions for this process on the motobrick site.


reassembly commences


but wait...while i was in there..bought a larger hella horn to replace the anemic stock one.  ez replacement, much louder!


all back together.

Bummer on that air leak - you were sooooo close to it before. Glad you found it though.

I've learned a lot from this thread, thanks.  :2thumbup:

Marshall locking ring is common to all Hella H4 lights including cars, you can get them from the wreckers. A couple of weeks ago I was in getting other bits for a mates car and asked for one, they didn't even charge for it.

will pick one up and repair the lens i have as a spare.  heck, i have a few old round H4 bulbs in a bin somewhere....

as soon as i got the lens out of the bike where i could see it, i saw that you could probably just bend the tabs up and take the lock ring off.  oh well, already had a pretty new lens!

after the RTE this morning, got inspired to install the Fox spring/shock.  pretty easy.  hydraulic line was just barely long enough to go through battery area and get the reservoir past the Z bracket.

a bit of difference in size (and weight!) from stock..




did not have the right size hose clamps, so temporarily used some heavy duty zip ties to secure to frame rail


then set sag...no idea what spring rate came on this shock, but it works out to be pretty good for my weight.

The shock cleaned up well - and I hope it serves you well. It should be a nice upgrade from stock, especially if that was the original shock.

I have one of those shocks on my K100RS, and would really like to know how to go about tuning the damping adjustments on it.  So far I have them pretty much at the lower end of the settings(I think) and will be riding the bike to see what they do.   Right now, the ride on the 100 feels better than either of my 75's which have Works Performance shocks.  The compression damping on the Works shocks is not adjustable and is a lot harsher on the crap pavement I do a lot of my riding on.

Has anyone here set up a Fox Twin Clicker on their brick?
