Well, in a fit of delerium I took the carb apart from my 92DR350S.  First
I drilled off the air pilot screw plug (one thick mother) and backed it 2
1/2 turns from the seated position.  I put a 1mm washer on the needle so
it stayed backed out of the main jet nozzle just a bit.  I put it all
back together again (after stripping the pilot jet - how the hell do you
get that thing out of there? and tearing the float seat o-ring - dammit!)
 I was amazed that the bike started after such a nasty assault.  I rode
down the street and did a wheelie (my version of a wheelie) in 1st but
couldn't do one in 2nd.  I figured this was the best way to test the new
awesome results of my carb mods but the bike failed the test.  However,
this simple adjustment did give me quicker throttle response and the bike
doesn't seem to run so lean anymore (my expert opinion).  I'll be
interested to see if the Thumper racing JX needle does anything more.  I
wonder if Thumper is just selling parts from another carb like the DR350
dirt version.  Anyway  - I guess things went OK with my mod and the
washer on the needle thing seems to work well.

I have set up three DRs dirt models and they are still going including mine
I believe the Thumper is the best way to go due to the Nascar wrist pin
which seems to hold up better. I bore the carbs out to 35.175mm ,do the
magic air box , white bros oversize header & megamax silencer and megacycle
mild cam with R&D springs.
these are 1990 year model bikes and have been in service about four and a
half years. I am semi-retired and have a small shop in Grants Pass OR. I
used to be a Suzuki dealer in Montana. [e-mail] hope this gives you
something to think about. Incidently these bikes do haul A---

 Well since I made the midget comment let me explain that I was just pulling
gino's leg a little. Believe me when I say that this is not the place that I
get confrontational. I save all of my hostility for my local authorized
Suzuki dealer. As to getting a little silly, all I can say is man I gotta be

Chuck, don't be so sensitive.  This good natured discussion has been going
on for some time now.  However, if you are under 4'10" tall, please forgive

On the silly side.

Are you pulling Ginos leg because the only exercise it gets is when he walks
back into the house for his second cup of coffee after pushing his magic
button??

I personally enjoy my kick start DR for several reasons. On cold Michigan
mornings kicking the thing to life is an opportunity to warm up before
blasting down the trails.

Secondly, if the bike is tempermental about starting (a rare occurence) , it
inspires me to ride cleaner at the start of a loop as I know I won't have
the energy to pick the bike up if I go down. Crashing early would  require
that I wait for my riding partners to catch up to help. On several ocasions
they have miss interpeted me laying under the bike. I do     this to let
them know  I need asistence. They think its my way of letting them pass
without hurting their youngblooded ring-a-ding egos. Usually the smell of
2-stroke oil as they roost past is enough to rejuvinate me. I have no
trouble restarting when there is fire in my eyes.
Sorry, too much coffee this morning and the wife has a silly rule about
starting work in the garage before sunrise. I sign off as the sun peeks over
the eastern horizion. Its supposed to be 60 and sunny in Detroit today after
a week of rain. Looks like a good day to ride.

  Uuhh, not exactly.  Let's just say I bounced off of it, but I didn't
go down.  If I don't go down, then I figure I win :-)  The only guy I
know that knocked over a tree was Merf.  And it sounds like the tree
got revenge because when it came down, it landed on him and flattened
him pretty good (he did eventually get up).

I just went riding this morning to try out my new carb mods.  To recap, I
put a 1mm washer on the needle of my 92dr350s and have cut holes in the
top of the airbox.  I have a stock muffler, airbox,  filter - I have a
135 main jet, stock pilot jet and 2 1/2 turns from seated position for
the air pilot screw.  I haven't installed the JX needle/ spring yet.  The
results are as follows:  There is definitely more responsiveness in mid
range.  On the trails, there was a noticeable improvement in 1st through
4th gear all the way through to  wide open throttle.  I had to watch
myself because the bike lurched forward a little  in 1st and 2nd because
of what seemed like an increase in power compared to what I am used to.
The bike also seemed to run a little quieter but that might be my
imagination.  Wide open in 6th on the road  to the trails wasn't changed
noticeably - neither was top end speed or rpms at top speed.  The bike
idled and coasted fine.  It doesn't seem to be running lean anymore.  I
am very pleased!  I don't think I will use a bigger main jet for fear of
causing the bike to run too rich.

Subject: (dr350) bryan's carb saga...

I know you guys cant wait to know how I'm coming along with my carb,
so here it is:

I'd put in a Thumper JX needle & spring, a 130 main (stock 127.5), and
a 40 pilot (stock 37.5).  Ran great at mid & high rpm, but was rough
at idle....too rich.  Put the stock pilot back in, drilled out the
brass plug, backed out the pilot adj (fuel mix?) screw 1 full turn,
put it back together & it ran great everywhere & iddled smooth.  Good
throttle response.  A few of you had warned me that I may have screwed
up the float level when I had it apart, but I guess I didnt.

With all that being said, I just got back from the MX playground,
doing about 30 min of small jumps, woops, etc.  After 30 minutes, bike
started running really rough.  Got back on the hiway heading home, &
it smoothed out at full throttle & eventualy ran well again.  Right by
my house there is a 45 degree long high dirt hill that I rode up &
down about 5 times, & sure enough, the bogging/cutting out started
again.  Went away on my way home after some full throttle street time.
 When I looked at it in my garage, there was some gas dripping off of
my idle adjustment screw, & gas was all around the bowl.  I dont know
what the deal is....after I wiped it off, it wasnt still coming
out...no leaks or anything.  I guess the hill made it happen.  Whats
going on here?  Are these carbs on the SE's not tough enough to do the
wild stuff in the dirt (not that what I was doing was wild)?  Are the
dirt only carbs not CV?  Does that make them alot better?

Subject: (dr350) Change your stock fuel lines!

Forgot to mention in my last carb update post..

I ran about 50 miles between recent carb tear-downs.  Time before, I
completely cleaned the bowl, float, everything.  There was alot of
fine black powder all in there.  This morning when I tore it up,,,er,
open, the black powder crap was back!  This is the deteriorating cheap
lousy fuel line that Suz put on!!  I put it back together w/ some neat
looking super thick transparent blue LeMans urethane fuel line, and
stuck a high-flow steel screen filter in line for good measure.  Next
time I tear it open, I bet I dont see the black powder crap.
