Feuling Pump / Cam Plate
I've run 2 of the 2000 to 06 pumps and after some mileage the both exhibit the same no pressure for a few seconds.. Not having pressure is not much of an issue on the early TCs but I'd worry on the later ones where the outer cam journals run in a plain bearing. Probably good to get pressure up as soon as possible on those..
I swapped out one of the Fuelings with a SnS pump and the pressure issues are much better. Gerotors are bigger so the pump recovers from any leakage quicker (still new tho) .
Picture of Fueling rotor on top of SnS.
The duel scavenge rotors fix my sumping problem that I had with my FXR twincam where the single scavenge rotor of the Fueling couldn't handle constant RPMs above about 3000 for extended periods of time when the ambient temps were high (over 100). Motor would drag down and heat up until allowed to idle for a while.. Then it would recover quickly and run normal.
So I might have missed it but what did you do to resolve your low oil pressure?
Thanks for your time.
Also do you remember any of the oil pressure values you had with the bad plate and the good plate?
Pressure
Oil temp
I really appreciate you answering my questions!
I didn't ride the Bike with "the bad plate",, the Tech and the General Manager didn't want to release the Bike with a malfunctioning Oil System ('Don't blame them,,, I wouldn't either...)
After 25k miles Dakota Digital Oil Pressure and Temperature Gauges were installed,,, Oil Temp stays < the low 240s in almost all conditions,,, Oil Pressure 38 PSI at extended 100 MPH running,,, 10 PSI at heat soaked idle ambient temps in the 90s...

2 problems. Jim Fueling died in 2002.. You don't need a special cam plate. If you were going high lift cams and heavy springs, maybe..

So I just wanted more info on your experience to compare notes. Weve used 3 different oil pressure gauges, OEM dash gauge, VDO mechanical gauge with 5 pound increments and a OTC mechanics oil pressure gauge test set we bought for testing purposes. We also have a laser temp gun for temp accuracy, on my bike I put in an oil temp gauge to replace the air temp gauge, ironically the oil temp gauge is close to the temp taken off the oil pan next to the oil temp sending unit.
The OTC test gauge netted the best pressure of the three.
My test details:
I did a cold start pressure,
At 2 min took another pressure
At 5 min another pressure, one at idle, one at 2000 rpm and one at 3500
At 10 min pressure at the three rpms and started noting oil temp
At 20 min, idle, 2000 and 3000 and temp
And last the same as above at 25 min
To some degree Im starting to think we are chasing our tail.
I have the stock cam plate in with stock tensioners, the Feuling OE+ oil pump and an LMR 002 oil pressure spring. I have acceptable oil pressure at all rpms and oil temps now.
Im in Minnesota and right now its kinda hard to do real life testing. The best I can do is a static heat/pressure test in my shop.
Im fortunate enough to be able to do all the work myself.
Like I said, short story. Lol!
Anyway I cant attributed the pressure issues to any one thing at this time, so thats why I asked you about your experience so I had some ideas on what your issues where. Im in the process of elimination at this point.
Thanks again for explaining your experience, I didnt have fluctuating oil pressure issues, just lower than I had anticipated at temperature.
Thank you sir, I appreciate your time!

Also a big fan of the Dakota Digital Gauges, very accurate, easy to read, it's nice to correlate the readings in real time going down the road...
