Taking a SEM second look...

FYI, I visited KRW sport cycles in Phillipsburg, Ohio today, a former Husaberg dealer, current KTM dealer. I talked to the owner Kirk about many things and found out he used to be a professional "wrench" for a Husaberg racing team. He had come up with a lot of tricks during that time to deal with the issues associated with the bikes of the 90's. The one I found most interesting was the venting of the ignition cover to keep the stator cooler. I have already performed this modification on my bike which I found out my bike was called "The Colorado 500". He told me the bike is rare and has different suspension settings and adjusters that differ from the regular 95 FE600E. He said there were other differences that he couldn't recall at that time. He went on to tell me that he had reason to believe that the SEM failure were due to 2 different problems, Heat and a bad grounding of the stator to the engine case as a result of the winding varnish under the screw heads. His fix was to scrape off the varnish under the screws and use a dielectric grease to prevent corrosion and then to vent the cover. This was done by drilling 2 holes at about 10 O'clock and 2 O'clock and run the later mentioned to a independant filter next to the side-frame-filter by way of elbows and rubber tubing and then to attach the other to the frame box or to atmosphere. He used a temperature strip to check temperatures before and after. He noted a 40 deg.F difference. I know that I found pictures of this mod on the web but dont remember if it was here or there. If anyone knows, please advise. Hey said SEM failure was majorly reduced.
On another subject...he has a 2005 KTM 525 supermotard with second set of off-road wheels/tires and fender. Bike has one race on it and was for sale for $4999.00. I know it's not a Burg, but my mouth was watering anyhow.

Hope this helps someone,

The Urethane coating on most ML wire
should take continuous 225 F with no
problem.Any higher and it gets soft
and about 325 F it will melt.It can get
brittle after continued heat cycles and
extreme vibration can make it fail.
Good metal to metal contact with
the aluminum cover will act as a slight
heatsink also.(just don't heat sink the wire) :lol:
 
This topic seems to go on for ages yet never changes all that much. We all recognize the inevetitable, the SEM rotor will fail sooner or later. However whilst i was searching ebay (today) i found a Berg owner trying to sell a long range tank for a pre 99 Berg. Nothing strange here except i noted a weird thing bolted to the side of the motor where the SEM rotor should be. Anyone got any clues?

Hi Bahnsy,
It is a Billet cover possibly from some of my earlier inventory.
A couple of others also jumped on the band wagon when Husaberg replaced their OE cast covers with that of plastic junk.

Hope all is well.
Best Regards,
Dale
 
Maybe they were just ahead of the times.
In the last few years new strides have been
made in the plastics industry.I am suprised
some of the plastic/carbon fibre composites
have not made there way to motorcycles.
Aluminum was tried in the 1920s or 1930s
on motorcycles and deemed unsuitable
do to it's poor durability at the time.

The original items were cast Aluminum.
The second generation were that of plastic "junk". :D

No strength and prone to leaking.
 
What I ment was there are plastics now that are stronger than
cast aluminum,and that Husaberg had a good idea.It just was
not developed properly before utilizing,of course they did that
way too often.

Hi Tim,
No argument here as I do indeed know what you meant, however, the plastic used was that of a toy soldier and an obvious cost cutting measure as opposed to any leap forward regarding advanced technology.

Personally, I hated the plastic ignition cover and valve caps hence my early line of billet replacements. :D

Sincerely,
Dale
