Couple items I am having trouble with. Have an 01 with 190,000. 50hp injectors and a newish DTT Assassin lift pump. Original VP as far as I know. I do run 2-stroke at 1oz/gallon. Ever since I installed the assassin lift pump I have been having trouble with consistent fuel pressure. For those that don't know the DTT is a mechanical fuel pump that drives off the harmonic balancer, so in theory, as rpms increase so does fuel pressure. I have yet to see this happen. Right now I will idle at 17psi and drop to 10psi when I get into the pedal. I changed out the fuel filter a couple times and when I do the problem goes away for a day or so, then returns. I was curious if anyone else running 2-stroke had seen any issues with pressure drop across their stock filter? I am thinking about trying a Wix filter, but I hate to keep dumping $20 into filters. I have been through 2 or 3 already this summer trying to troubleshoot and only put on about 5,000 miles. 2nd item: The other day I was cruzing down the road about 50mph and the tranny seemed to shift into neutral for a second, then back into OD. I was able to get it to repeat sporadically, but it seemed to be when I was under a very slight acceleration. It also happened this weekend when I was pulling the camper out, but I'm pretty sure it was in 3rd gear. It seems to shift to neutral for a second, then back into gear. Tranny was flushed within last 20,000. Fluid level is ok, but I will check again. I adjusted transmission bands last summer for the first time. Any thoughts? Thanks.
