guys / gals......

i've made posted so many topics and i'm sure you sick of me, but i'm really getting fed up with this dale......new motor as i'm sure everyone know's......broke it in yesterday for 45-60mins and had a stalling problem, but it would run fine for 10-20mins.....found out that there was a kink in the fuel return line.....fixed it today and now it will crank on with no problems, but stall very shortly after! WTF!!!

i've checked the fuel filter and the flow of gas returning to the tank.....it's a strong stream to the second it stalls......

what do i need to look for....the EFI thig is really bugging me....i've got alot of money and time in this quad and its really getting frustrating......i've only been on her for 1 1/2 hrs max with the old and new engine. This is a new symtom that jsut popped up out of no where. I also tried the key in both positions and opened it up and cleaned the contacts. My next step is probably to hard wire the on and off switch, but i doubt it is the problem.

oh, and right before it shuts off it slightly revs higher.....like its leaning up or no gas, but the return stream as noted is strong to the last milli-second

this just sucks.........

That wouldn't surprise me any. I could see it acting that way if it wasn't making good contact. I was thinking it was an electrical issue. Everytime I have something going on that I am just SURE must be fuel related, it always turns out to be electrical.

You think it woulda blown the fuse though if it wasn't making good contact...interested to see if it stays running right for a period of time longer than a minute...I just find it odd that with the vibration of these machines and if it wasnt making good contact that it would run at all...I hope this was the culprit though...keep us updated.

I've had a fuse tease me. Get to a RPM and it would die. Checking the fuse is one of the things I look for when hunting down a problem

I guess so...I've just never had a problem with mine unless it was blown.
