Subject: (dr350) DR Headpipes

John,
As far as headpipes go, Thumper Racing has a ceramic coated one, $150.
Big Gun or FMF may have them also. I have one from White Bros. but not
sure if it is still available, check their newest catalog. It looks just
like stock, no ceramic, was $60.
IMHO an oversize headpipe does not do very much, just look at the Dyno
readings for different pipes for the XR400 in Dirt Rider (or Dirt
Bike,not sure). With and without oversize headpipe about the same,
torque & horsepower.
                            Jim A.

Bryan;
Thanks for the info. I'd just gotten done looking at the Race Tech website
when your e-mail showed up. You came up with the same spring rate I did;
about a .430 is what I figured. I've heard some good stuff about the Kouba
link; sounds like a real easy mod to make and cheap too. How difficult is it
to install these emulators and what, if any, "special tools" did you need to
accomplish the job? After reading my shop manual, it seems like the fork
damper rod bolt would be the "tough nut" to crack in taking the forks apart.
What weight of fork oil are you using and at what level do you set it. The
Race-Tech fact sheet reccommends running a 15w oil which seems awfully
heavy......

Subject: (dr350) why no dr's?

OK,
Some of you racer types,  or former racer types might know this one.  I
went to the local hare scrambles this weekend at slades park in SE
Virginia,  which is a pretty cool place to ride by the way,  anyway I
was looking at the classes and saw 4 stroke A and B.  I did not see one
dr out there.  Why?  I think the bike would be fairly competetive with a
few mods.  Unless they are racing the yz400's and big xr's.  Then they
are kinda outclassed.  Is this biked doomed to a life of traildom. I
really dont mind,  I love mine,  and dont race it,  but it is kinda
unfortunate.  Any racers out there want to sell there dr REALLY cheap?
hehe
Thanks

Has anyone tried any of the European trips offered by Edelweiss, Lotus,
Beach, etc.?  What are the pros and cons of each?  I am planning on taking a
trip in September.
Thanks in advance.

Subject: (dr350) Re: R-T emulators

Bryan;

Thanks again for your input; I may take you up on your offer to buy the
springs. Please give me the particulars again; I cleaned out my mailbox and
dropped your initial response to my questions. I never would've realized this
bike is so popular; I wonder why more isn't written about it or hyped
elsewhere. Our local Suzuki dealer seems to stock only the RM's with maybe
one DR650SE on the floor. Heck, outside of oil filters and plugs, he doesn't
even stock parts for the bike; a clutch lever is a special order item. Honda
seems to have the lock on the medium to large, 4-stroke trail/enduro market
or so it would seem by all the press they get.

Let me know about the springs; if I decide to take you up on the offer, I
guess we'll have to work out some kind of monetary transaction.......

later

John,

I'd sure like to take you up on that offer to test ride your 441... i live in
Montrose,  maybe we could meet up at Texas Canyon after work as it's staying
light out longer or a weekend morning....still working out all the handling
bugs on my '91 DR and it would be great to hook up... Thanks

Hey,
I am thinking about driving up to the mill hall dual sport in PA.  I
have room for another bike in my truck,  I will leave from Southeast VA
friday evening.  My route will be through richmond VA and DC,  then up
to central PA.  If I need to make any short detours,  that would be OK.
Just go ahead and email me if you are interested.

Subject: Re: (dr350) Some basic and a dumb question

the "S" is the dual-sport model the "SE" the electric start version that
begins in '94.

Suspension improvements in order of cost:

1. Kouba links
2. Revalving and custom spring
3. Emulators and revalving and custom spring
4. Cartridge conversion and custom spring
5. RMX fork swap...
