1)Airbox lid removed
2)Throttle stop trimmed
4)White Brothers"E" series Pipe w/ stock header and 12 disks.
7)Needle-OBDRR clip in #3 slot
8)Fuel Screw-2 turns out
Bike just RIPPS all through the power band, @ 3000', but when I get to about 5000' it runs great until I shut it down and it cools off, start it up, take off and it pops and back fires @ 1/4-3/4 thottle? The bike starts fine,(never had a problem starting)Seems to run great @ WOT .I feel it has something to do w/ the needle, but I just don't know for sure..I thought about moving the clip up a notch thinking it was running rich do to my exhaust disks turning darker@ the higher elev. rides. I just don't know?I also thought the jets were fine due to the higher elevation..I have a buddy that runs the "DTM"needle in his wr400, same kind of situation, w/ a MJ-175/pj-45..So the only thing different is the "DTM"needle..I've been reading alot on this site trying to learn more about those needles, but it gets kind of confusing..Any help would be greatly appreciated!!! I think I'm really close!...Thanks........TIM

The DTM is a richer needle from 0-1/4 throttle. It depends on what clip it is set at whether jetting is the problem. #3 is usually a good setting.

I use a Moose multi-bit screw driver made to go in a fanny pack (4 tips in it). The smallest flat blade tip on it without the handle is short enough to fit. I can count the flats to check the turns out. Hot is difficult as it is tight to reach and gloves make it harder to turn, easy to get burned knuckles bare handed.
