That's funny. I just got the Ti Powercore 2.1 yesterday and am doing the same thing! I removed both brackets and am going to rivet just the rear one back on in the proper location and put rivets back into the original holes. It has a 30mm inlet pipe vs the 32mm on the k5 (28 and 30mm id's  respectively). I cut the inlet pipe off 1" from the silencer and have a straight section of 32mm od pipe from my scalvini pipe which slips right over the silencer inlet. The people at FMF were totally useless and wouldn't bother to even give me the dimsions of the few that they carry for modern 2 strokes so it was trial and error to find one close. I tried the YZ250 one first but it was only a 28mm inlet pipe.

Be sure to document what you did.
I'm sure there are a few guys that might want to copy you  cool

The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

I'm putting the races back in the frame.
I don't have any special tooling  undecided
But, I do have a old 2" trailer hitch ball that is a nice fit  cheesy



Good old ACME  afro

Reduce the outer diameter of ur old bearing outer race{grind it } and use up side down to tap the new bearing race home /cool the bearing will also help

Excellent suggestion but..... I removed brand new races so there was no need to order more, and grind the old set down as I am reusing the new stock races that I removed.
Further, I should have taken a pic while I was doing it... I put a rag under the ball... Just one layer...
The pic I posted was after I had done the deed and then decided I should post it but I couldn't find what I did with my clean rag..
I knew if I put a dirty rag in there people would freak  cheesy
I have done this same procedure many times over the years with no issues.
Then again, I don't beat the race up.
If you look at that hammer, it's very small and light.
I'll take a pic of the bearing surface later, as you will see this method does not damage the bearing surface in any discernible way.
I have done this same procedure and ran the races and bearings for over 15 years in the past so I'm sure these will outlast me and my bike riding days.  shocked

The top clamp is being replaced as soon as I get it.
I put this top clamp on to hold it together.
Also, I'm replacing the bolts with Ti  cool
