Default 107 tp motor

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
