drz400s aft rack and bags


ebrabaek

Just finished making the aft rack from 3/8 id stainless. Bags I sowed from 18 guage polyurethane coated fabric.

Here is the full rundown of what i did.

The only thing so far that i did was the airbox mod with the sewer hose to block the sound. That restored the bike from running rich to normal mayby a bit lean at 4000 feet and 90-100 degr. I felt that there was more to be done. In went the k&n su-4000 filter.

Dynojet kit for the drz400s. From the kit i installed the following parts: Big spring, needle, clip for the needle. I changed the pilot jet to a 25 from stock 22,5. Installed the kientech fuel screw, and put in kientech stainles screws for the bowl. I decided to leave the stock main jet 142,5 i think. I really like the results. When i pull up the highway 5% grade to 5500 feet the bike for sure pulls stronger at a lesser throttle setting. 0 to1/4 throttle good response and pickup with only little backfire closing the throttle. 1/4 to 3/4 throttle very strong pickup especially from 1/2 to 3/4 throttle. Maby a bit room for improvement about 1/4 throttle. when the needle circuit picks up at 1/4 throttle there is a tiny hesitation, maybe so little not worth mentioning. I think i have to run it a bit more to home in on it. And then figure out what to change...maybe try lowering the needle 1/2 step with the suplied spacer. From 3/4 to 1/1 throttle the bike pulls strong. So i believe the choice of main jet is fine. In the next day or so i will do a spark plug test. I left the fuel mixture screw at 1 1/2 turn.as per kientech recommend. It needed a bit more fuel from idle to 1/4 throttle so I ended up with fuel screw 2 turns out.....nice.

I am in the process of taking all the covers and make a negative fiberglass mold, in which I will produce a carbon fiber replica of the original plastic cover. Have one done so far....looks nice. The pdf slide show is of the rack and bags. I welcome any questions at: ebrabaek@sbcglobal.net enjoy

      So I thought I should create a new thread to dump my vlogs into for the few that do watch them.  If you didn't catch my vlogs from last year for 2017, check them out here -> 2017 NMA Series
      Season 2 is well underway for 2018.  This year I'll be racing the Open A class competing in both the NORCS and NMA off-road series as well as the Desert 100 and maybe some other races throughout the year.  If you got any questions or recommendations, lets hear them.  Enjoy!

      I bought a used 2009 DRZ400S that came with an extra Corbin seat that is extremely comfortable. Unfortunately as a tall rider the seat sits too low for me vs the stock seat. It is in excellent condition with a few wear marks shown in the pictures. Small holes on the back right side where I believe the fender rack might have rubbed it. A wear mark on the front left side that is just discoloration. Make an offer. Thanks!
