Indawoods. Did you get the Rectifier/Regulator and battery to work?
From your .pdf link to Baja designs. I believe you wanted to
use the bottom schematic for wiring up the KDX?!?! True?
I am in the process of this myself and I am looking for information
and experience.
BTW. Im-a-NooB on this site and need to write up an introduction
and post it.
Thanks for any help you can provide.

SM KDX :supz:
I thought about getting some 17" wheels a while back but the track I could go is pretty far and is a bit expensive so I dropped the idea (got my DRZ anyway :supz: )

Hey, good to see ya. I'd like some more information on your 240 kit. I looked into it for a while. Seemed there were lots of complaints of lost power up top. I dug around some more and found that the CDI works in conjunction with the power valves. IE there is a different timing advance from the CDI for under 6k rpm and over 6k rpm when the valves would be open. I think a CDI from an earlier bike that did not have KIPS might work really well there?

Just a though. Anyway, I look forward to your introduction and some info on your bike!

some pics of your bike (even in the building process) would be cool. :supz:

MY bike is a 1990 KDX200-E2. It does not have any electrical
connection to the KIPS valves. They are not (power valves)
like on a DT200 or WR200.
That said. The one draw back to the 240 kit is you loose the
main flapper valve. With the new sleeve and the 72mm (I believe)
piston. The cylinder diameter is too large to fit the valve.
The two rotrary valves along the side remain and function.
Since I am kind of old and slow, (always was), I can not really
comment on the loss of top end power. My bike was a 240 when
I got it, but, I have ridden friends stock 1992 KDX200-E4 and
my bike is as fast as his in every way that I can tell. Where the
240 kit excells is in the low-mid rpm grunt. It is harder to stall
and will motor over the slick stuff better that a stock 200.
It does not have the "hit" when the KIPS system kicks in either.
Seems smoother all the way through.
If I had a choice. I would stick with the stock 200. Jet it right and
work on the suspension first. Maybe add a flywheel weight if they
make one.
just my 2 cents worth.
Here is a picture of the bike we are talking about

Juliend, sorry I did not read your post and fully understand your
question before my reply.
Yes, maybe a different CDI map would make a difference in the
way a 240cc kitted KDX responds. With the loss of the primary
KIPS valve, you will loose some of the bottom end that the KDX
is famous for. I believe that is made up with the added cc's.
One thing I read about when researching the 240 kit was that
some folks commented about over heating issues. Mostly
associated with the Iron sleeve that replaces the Nikasil
lined Aluminium cylinder. For me I did not notice any over heating
issues with my bike. I have, (more or less), 2,000 miles on the
bike as a 240cc and never replaced the piston until I did the
restoration a few years ago. At that time the underside of the
piston showed some over heating discoloration, but, I never had
any signs of a seizure or problems with ring wear or loss of
compression.
-------------
I guess my main reason to join this group is to learn about the
KDX from other folks with more experience than me. I am happy
to share anything I have learned in the last 18 years of my
ownership of this KDX200.
I would like to learn about the detail of the electrical system
and what I can do to convert the AC stator into a DC system
that can charge a battery and run a set of lights much like the
KDX200SR that was released to the rest of the world.
Since I plan to make this bike into a SuperMotrad and get a
street licence plate for it. (long range goal)
I am not a (total NUUUB) at this. I have converted a GasGas XC300 into
a Street legal bike with a floating ground stator and Rectifier/regulator
system that will charge a battery, etc..etc... The KDX is a bit different.
I also have a thread going over and ThumperTalk with some of the
same questions and pictures. It is in the "poor man's SuperMoto" thread.
Sorry I did not introduce myself before getting so deep in KDXrider.
There are some very smart and knowledge folks here and I would
like to learn from them.
Thanks for your time and insight.
Jeff, So Cal.

Dang that is a beautiful 90! I have an 89 and a 90 in the garage. The 89 is mine, and it's pretty sweet. The 90 we picked up in FL for my buddy and it's a bit of a rag. We need to do the bottom end, and the sleeved cylinder just doesn't seem to run right, not to mention it has some major carb issues that I can not seem to resolve as of yet. We put a 35mm mikuni I had on there but jetting it is proving to be a challenge.

Anyway, really nice bike and welcome to the forum!

I have had HID on my KDX SM since last summer and that is basically how I did it. I floated teh ground and ran a small battery in the airbox. I run a powerful little LED in my UFO Ghibli along with a Halogen/HID bulb in the H4 spot. Most riding I will run the led to allow the battery to top up. Then I will use the HID or halogen when needed. I bought the more powerful lighting coil from you but have not installed it yet. I am sure that after I install it I will be able to use the HID alot more as even as is with a topped up battery I can go a few hours before the HID flashes.

dubtruker: When you say, " I floated teh ground and ran a small battery"
I assume you used the the electrical schematic at the top of the .pdf
file you linked to. Is that correct?
I am hoping to use the schematic at the bottom, and to not have to
"float the ground" on my KDX. It would make things much simpler.
After doing some web research on lighting. I am leaning towards going
the LED lighting route myself. VisionX Solstice looks like a great light.
http://www.visionxusa.com/LED-Solstice/c1_48/index.html
I am also thinking about either keeping the stock head light bulb or
using a Halogen H6M to replace the stock PX15D bulb. My shell will not
accept the H4 bulb.
Thank you for taking the time to answer my post.

The second schematic shows a floated ground. The DC side of things does not have the negative attached to the frame, I geuss if I did a little more research then I could have ran it all grounded but with the reg/rec I had from Baja it was the only way I could see to use it and not effect my ingition system.

ummm....okay.......?!?!?!?
Not what I thought "floating ground" means, but, I'll accept your
solution to HID and getting DC supplied to the electronics.
Thanks, Jeff.

Sorry to thread jack this post. I need to start one of my own.
But some progress has been made on the KDX240SM project.
Taken last night. Got the new wheels installed.

And a new Speedometer.

I put a H6M Halogen bulb in the stock headlight shell. We will see how
it works before I proceed with either HID or LED accessory lighting.
