  1. I would like to be your guest that weekend.
  2. I wrestled the carb out of the bike and inspected it. The slide was in correctly and operated fine. One of the velocity stack screws had backed out though. I will get some carb cleaner and squirt in the pilot jet opening tonight. Is there any thing else to check while the carb is on the bench?
  3. No since the carb was brand new. I will though when I remove it to check the slide.
  4. Thanks your help on this. That web paged is blocked so I will have to check it when I get home tonight.
  5. The carb came from with: 185 main jet 200 main air jet emm needle-4th clip 55 pilot 60 starter jet I didn't record the settings of the pilot air screw or the fuel screw. I just turned them all the way in and then set them to the recommendations you gave me last fall along with changing the main to 150 and the pilot to 38. Yes I did have the slide out to check the needle and clip position.
  6. Eric, I bought a used bike that was totally stock with less than 2000 miles, all street. I rode it twice around the parking lot and then started taking it apart for this project. All the mods including the carb are brand new parts that have not been on the bike before and it was all done in one stage. THis weekend was the first time it ran since I started the project. Thanks
  7. This weekend I fired up my 2003 KLX400SR for the first time since rebuilding/modifying the motor, breaking it in per mototuneusa.com method. The first 6-7 attempts to start it failed. Then I tried pumping the throttle about half way or more and it coughed twice and fired up. When I let the throttle go it stalled. Got it started again and kept the engine running a little faster than a fast idle to get it warmed up. Then I blasted around the parking lot to test it out and start breaking in the motor. It ran great. Awesome power and throttle response. It pulls very hard and smooth with no hesitations or faltering. In third gear it felt like the throttle was an altitude control for the front end. The more I turned the throttle the higher the front end came up. It didn’t feel like a wheelie because I wasn’t trying to loft the front end and it was so gradual. Very cool and the Muzzy exhaust really sounded great. I stopped and tried to adjust the idle speed and it stalled again. It took multiple times to start again. Then I headed out to a nearby power line to continue the break-in procedure. It ran perfectly as long as I was at 1/3 throttle or more but it stalled more off-road when I slowed too much or tried to lug it in situations like coming out of a ditch. Bottom line, it is still hard to start (I ended up killing my brand new battery) and it absolutely will not idle. By the way it is not the vacuum line to fuel petcock. What’s wrong, where do I start? Thanks to 10guy, Burned and the DRZ-400 forum for all the guidance in this project. Motor mods: Millinium Technologies bore/plate 94mm big bore kit, Hot Cams stage 2 (int + ex), HD clutch springs/friction plates, Sudco FCR39 kit, NGK CR8EK, TT MCCT, Muzzy full exhaust system, 3x3 mod with backfire screen removed. Also sent the head out for complete valve rebuild/inspection using new 1-piece stainless steel valves, stock springs and shimmed for new cams. Burned recommend jetting: 150 main jet 200 main air jet emm needle 4th clip 38 pilot jet 60 starter jet 5/8 turn pilot air screw 2 turns fuel screw. Boysen AP cover Taffy mod AP duration = 2 seconds
  8. I finished my KLX400SR project with the big bore, hot cams, one piece SS valves, Muzzy exhaust, FCR and air box mod. It is jetted per Burned's previous recommendations. I wish I could to take to Colorado and have Eric break it in for me on the Dyno (I haven't fired it up yet) but I live in North Carolina near Greensboro. Anyone have any recommendations of where I could take it in NC or Southern VA? What questions should I ask?
  9. So much good info on how to fix. I don't think mine is leaking yet, but what/where should I be checking to make sure I catch it if it starts to leak?
  10. On my S model, I just installed a Muzzy S model Ti oval slip-on silencer onto my FMF Powerbomb header which is the same for all models (large diameter). It fit perfectly with no modifications. Thats because the stock S-model silencer uses a reducing bushing/gasket in the clamp joint that would need to be reused if I had the stock headpipe. The cool part is that the Muzzy silencer used the stock foot peg exhaust mount, and like I said, it all fit perfectly.
  11. The SM event at Birch Creek near Danville, VA is supposed to have a freestlye exhibition also. Any TTers racing there?
  12. I just got an FCR kit (with choke) for my 03 KLX400SR from Sudco. I came with everything needed. It fits in the stock intake tube and aircleaner outlet and uses all the stock clamps. It even came with a throttle and new cables. They will pre-jet the carb to your specifications also. I am very pleased. I'm not done installing the big bore kit and Muzzy exhaust so I haven't started it yet.
  13. Just curious; how does the CDI know which stroke is the compression stroke?
  14. Thanks for responding 10Guy. The elevation should be between 400-2200 ft.
  15. I am about to install my Millinium Technologies bore/plate 94mm big bore kit, Hot Cams stage 2 (int + ex), HD clutch springs/friction plates, Sudco FCR39 kit, NGK CR8EK, and Muzzy full system on my 03KLX400SR (3x3 mod with backfire screen removed). Also sent the head out for complete valve rebuild/inspection using new 1 piece stainless steel valves, stock springs and shimmed for new cams. Planning on the new TTMCCT when available. Any advice/tips on the installation beyond what the shop manual says would be appreciated including reliability issues. Also looking for brake performance upgrade suggestions. Jetting: 150 main jet 200 main air jet emm needle 4th clip 38 pilot jet 60 starter jet 5/8 turn pilot air screw 2 turns fuel screw. Thanks in advance.
