2008 dr650 carb issue

I have 800 miles on the bike, I loosened and turned the carb on its side, drilled the cap on the fuel air mix screw, pulled it off so I can adjust it, I turned the screw in the whole way, then I turned it out 2 full turns. I took it for a ride and now at full throttle it backfires and boggs out. What should I look for, or Where should I set the screw?:smirk:

thats strange, the mixture screw should have no impact beyond about 1/8th throttle. Go back and check everythings tight and seated, theres a hose on the top right hand side of the carb that can fall off make sure thats still on there and not kinked

I called the local cycle shop and he said turning the carb side ways caused dirt to possably enter the main jet! Does any body agree? I guess i'll pull the carb and clean it.

Well from your operational issue mentioned above it certainly sounds like your main circuit is leaned out for some reason. I have a hard time believing an 08 DR650 has that much crapola in the carb though.... it's got petcock filters and an inline filter in the fuel inlet tube on the carb. :thumbsup:

I just installed a Stage 2 Dynajet on my 650. I drilled out the plug and installed an extended fuel screw in place of the original.The fuel screw setting was 3/4 turns out. Hope that helps.

Check the choke cable at the carb, make sure it's ok.

WOW!!!!!!!!!!!! I took the carb off and it still looked new. I put everything back together and still cuts out when I ride it. I was coming back up the street and I hit a pot hole and it cut in and out??? what the heck???? I got back and studied my bike for awile and holy cow the side stand was barely pushing up on the kill switch!!!! I put a zip tie on the switch and went for a ride and it ran awsome!!!:thumbsup: I didnt ride it since October 07. The bike set for 5 months and the kick stand springs are stretched out????? I bought it new in august 07. Does any one know of better springs??

Are you sure your pivot just doesn't need a bit og lube? Either that or you can jump out the switch....

The kickstand springs are defenetly stretched out! They have a 1/4" gap in both of them when they are off the bike. weired? Maybe hit by a rock?
