Due to the popularity of the DRZ-400SM and the amount of people riding, buying and modding them, I decided to merge a few good informative threads into this "DRZ-400SM Ultimate Thread". I hope this helps many and if you have new info, please post it here! Thanks and ride safe!

Tumper talk- more DRZ400 info than you'll ever need!!! http://www.thumpertalk.com/forum/forumdisplay.php?f=25

Here's a cool list of upgrades, parts and stores that some recommend.

Lowering your DRZ? - http://www.koubalink.com/drzinstall.html

Wheeling cycle supply, home of the Zeta Levers, http://www.wheelingcyclesupply.com/s...gory&cat_id=72, and so many more cool bits for the DRZ SM. http://www.wheelingcyclesupply.com

Tires- most of us really enjoy the Avon Distanzias, they are SM specific with plenty of grip in the twisties and decent off road traction too.

Hi All,

I just picked up another DRZ400SM (3rd one!) and this one is bone stock...

I actually bought this bike to race next year in the AFM 250P class, but I would still like to be able to ride it on the street. The bike is an '05 Yellow/Red model and has 800-miles. It's practically brand new. I specifically choose the '05 model as current rules allow unlimited motor mods, but no big bore, and stock carb/airbox)

Here are the current mods:

Renthal Fat bar kit
Acerbis hand guards
Yoshimura RS-2 full exhaust system
FMF Jet kit
Goodridge SS brake lines
EBC HH pads

-

My next step is to remove the front forks and have them revalved/resprung, but other than that, i'm not sure what else to do. Cams? E-model base gasket? Ceramic bearings? Lighter flywheel? Anyone know how to make a 'good' looking belly pan for this bike?

I got the bike for a song, so I have a bunch of cash left over to do some motor mods. What do ya'll suggest?

Mortifer · 11-27-2007, 03:11 PM

lol, congrats!!!

Cams and e gasket are a good start i guess.
Cermamic bearings requires a full engine tear down.

Just get a pipe, jet it and enjoy!!!

Papi-C · 11-27-2007, 03:26 PM

anything else special about the 05 besides this rules thing?

FrigginChi · 11-27-2007, 03:41 PM

daddy will take care of u.

stan23 · 11-27-2007, 03:48 PM

Other than the rule exception, I like the yellow. More specifically, I like the yellow/red combo. You saw how many blacks there were at the techday?

FrigginChi · 11-27-2007, 03:50 PM

Hooli won't like that!

FrigginChi · 11-27-2007, 04:03 PM

no big bore for 250 afm class though right?

stan23 · 11-27-2007, 04:11 PM

As I stated above; you can't change the carb, or even modify the airbox. Internal engine mods are ok -- except for big bore.

If I could do the carb, it would be on the bike already!

Russell - many thanks for the link! :-)

My finger is hovering by the buy it now button, but I realize that the bike came with a similar belly pan. However, mine has a hole cut out for the drain plug, and i'm sure that is definitely not legal. Can I just cover up the hole?

1kneedown · 11-27-2007, 04:31 PM

mine definately does not have a hole for the drain plug. I double checked the photo and it looks the same. The four holes in the bottom are all mounting points.

Oh, what I meant was mine came with a similiar belly pan made by a different manufacturer. The only real difference I can see is that mine has a hole cut out for the drain plug, and the one on the ebay link doesn't.

I'm wondering instead of buying a new one, if I can just re-use my old one by covering up the hole?
