metallstick Posted December 19, 2004 I have made some changes to the carb on my bike and am having a bit of trouble getting it running right on the bottom end. DRZ400E 02 supertrapp IDS2 pipe coast enricher removed operate mostly around 300 ft msl 158 main 48 pilot Pilot airscrew set at 7/8 open Fuel screw set at 2 1/2 turns open bike starts and warms up with choke out. When I push choke in it continues to run at high idle for about 10 sec. It then idles down and about 10 sec later shuts down. It will restart with choke in and when I blip the throttle is stays at high idle again but then settles and will shut down. Ideas wanted on how to tame the beast.

Wayward Son Posted December 19, 2004 check for air leaks,plugged pilot jet,mistaken pilot jet size or mistake pilot air screw setting. removed the CE?capped the holes? Share this post Link to post Share on other sites

Thanks, Mike c 48 pilot and 7/8 turn should give you rich idle. You describe lean symptoms. I would look for a problem as burned said. This is not just a jetting issue. Is the carb on (in the rubber boot) all the way? Share this post Link to post Share on other sites
metallstick Posted December 19, 2004 I will go back and start over. I am going to blow out the jets and reinstall them and see what happens. When I pulled the coast enricher I sealed the connection with ATV sealer and a vacuum plug. I agree it sounds lean but if these things are all fine I am not sure where else to make an adjustment.

Mike c When you removed the CE you had 3 nipples to plug. 1 on the head, 1 near the center of the carb and 1 close to where the air cleaner boot attaches. All 3 are important to seal. The center 1 is the most important that will affect idle. I think you are looking for "what did I do wrong". Normally for a 48 jet you would set the PAS at 1 turn. What is ATV sealer? Do you mean RTV? RTV is not for gasoline applications. Use tight fitting cap plugs. Share this post Link to post Share on other sites
metallstick Posted December 19, 2004 I used RTV sealer. I will go back and correct that. At the same time ensure they are seal good. I thought they were good when I did them. I hope I made an error that resealing will correct. Thanks Share this post Link to post Share on other sites
