My lower oil filter bolt threads gave up this weekend on my 06 YZ450; so now it is time to repair them. I am planning to do the Time-Sert repair. After watching the video the instructions show that the hole should be counter-bored to accommodate the little lip on the insert. Does the lip on the insert interfere since the threads are actually quite a bit inside the case? Is the counter bore even used for this application? Any advice/insights on this are appreciated!
