tp engineering 107
i have a 107 tp engineering motor with a oil belching problem if it sits.normally, a easy fix.i first send the oil pump to tp to check the ball and seat that prevents this from happening.i get it back ,same problem.send it back,re install,still happens.they ask if i used any terflon tape that could be in oil,no.do i have an evo filter not a twin cam,yes.is my oil level correct,yes.i have now changed the oil and filter 4 times.frustrated i order a new pump,oil tank,replace the oil lines,install a crank case breather.have a bike shop install another piece in the motor they suspected to be the problem.checked gaskets to make sure thier right.problem still there.after five consecutive oil changes,new oil pump,lines ,tank,on a 6000 mile engine tp says my problem is debris in my oil.this is the cleanest oil,no metal,no gunk,its so clean you can see the floor perfect when it shoots it out the breather.i can re seat the ball with air pressure.i think i will install a ss pump.the problem is with the oil pump ball and spring.has anyone else experienced this problem thanks

I've had this with a very early 100" RT motor and a 113" TP. Both were resolved with an updated oil pump assembly.
Just for grins make certain the return line to the oil tank is the return port. I had a 124" TP here that was spewing oil from the head brathers. I eventually (after checking everything else) traced it to a bad return line in the tank. The internal line had broken off in the tank not allowing the oil to return to the tank.

This is a possibility. You diagnosis is wrong, I suspect. If the standpipe in the tank broken off, Oil can back flow from the return line to the motor. Simple check. Remove the oil return line from oil tank. After a short while oil dribbling out of the tanks should stop.

TP engines did not have a history of that, as far as I know.
On most any gravity drain oil tank, the crankcase will build with oil after even 2 weeks, +/-, w/o being in operation.
We have many calls in the spring of each year regarding oil spitting from the breathers.
A dirty trick would be to have them bring it in, just to run up a work order on them, but we instead, we explain, and they appreciate the honesty, which has been a cornerstone of our 30 plus years in business.
