Hey,
My brother got a 06 ltr450 a little while ago. The performance mods are a yoshimura pipe, pro design intake kit, and yoshimura programmer with a programmer. I picked it up for him and everything rode great with it. I took it out a few times and coming from a 450r, all I gotta say is this is a mean bike. Well anyways, I rode it around a little and everything felt awesome. A few weeks after I picked it up we headed and rode at bpg. My brother rode the bike around for a while with no problems. The tracks were pretty muddy cause we got some heavy rain the night before and in the morning it was a little difficult to hit the jumps hard. As the track started to clear up the bike was being jumped a lot farther. I took it for a spin and the bike booged out in mid air and it wants to nose dive. Throughout the rest of the day he noticed the same deal. It revs perfectly on the ground but, once you are airbourne it boggs. Just the other day I took it in the yard and hit the jump and felt it. Anybody experience this or have any tips? I am completely new the the fuel injection. I don't know if it has anything to do with the pump or what but, any info would be greatly appreciated.

Thanks a lot,
Andrew

the same thing happened to me after riding in the mud at bpg...since i have a inline filter i could see it wasnt that so i drained all the fuel and then refilled it and it work...guess there was some water in there from mud or the pressure washer

Its probably the fuel filter but could also be the tip over switch.. Tip over switch usually doesnt mess up unless your really G ing out

My money will be on the fuel filter.Dont bother buying a new one,just strip and clean it out and put it back.
